21 Basic software Saving and restoring the window layout Overview What is saved? The STEP 7 applications allow you to save the current window layout and restoring it at a later time. If you save the window layout, the following information is recorded: position of the main window opened projects and the associated window positions sequence of windows which may be nested Save window layout Restore window layout Information regarding the object hierarchy To save the current window layout, select the menu command Window > Save setting. In order to restore a saved window layout, select the menu command Window > Restore setting. When restoring a window, only that part of the hierarchy is displayed in detail, in which the object lies which was selected when saving the window layout STEP 7 option packages for D7-SYS - SIMATIC D7-SYS

22 Basic software 1.3 STEP 7 projects and basic handling Overview Projects represent all of the data and programs associated with an automation solution. They are used to save all of the data and programs associated with the automation solution in an orderly fashion. The data associated with a project, include configuring data regarding the hardware structure and parameterizing data of the modules. programs for programmable modules. The main tasks when creating a project thus involve preparing this data and creating the programs. STEP 7 does not specify a fixed processing sequence. You can start with any partial task. Information when reading The first part of this Chapter describes, use an example, the essential project components Opening a project example You can display the properties of most of the objects using the menu command Edit > Object Properties. This gives you an impression of the information which is assigned to the object. Basic handling of objects associated with a project are described in the second part of this Chapter, for example, opening, copying and renaming. The systematic procedure when setting-up your own project is described in the Chapter "Setting-up and processing projects". Opening the project, displaying the contents Project window To select and open a project included in the scope of supply, please enter the menu command File > Open > user projects or project examples... Then select a project. The project window is then opened. The project window is sub-divided into two sections. The project structure is displayed in the lefthand half. The contents of the objects, marked in the lefthand side are displayed in the righthand side. To display the complete project structure, click on the box with a plus symbol in the lefthand section of the window. You will then obtain a screen similar to the following: STEP 7 option packages for D7-SYS - SIMATIC D7-SYS 1-11

23 Basic software Fig. 1-4 Project window Object_hierarchy Several objects in the real world have specific interrelationships with one another. These interrelationships from the real world are illustrated when displaying the components of a project in the project window using a logical hierarchy. In Fig. Project window, at the top of the object hierarchy, the "FIBEL_BSP" object is displayed as symbol for the complete project. It can be used to display the project properties and is used as container for networks (to configure networks), stations (to configure the hardware) as well as for programs (to generate software). The objects contained in it are displayed to the right in the project window if you highlight the project icon. The objects at the top of the hierarchy (this also include, in addition to projects, also SIMATIC libraries) allow you to go into the dialog boxes to select objects STEP 7 option packages for D7-SYS - SIMATIC D7-SYS

24 Basic software Components to configure the hardware Icons Icons of specific components: MPI network SIMATIC TDC/SYMADYN D Fig. 1-5 Specific components to configure the hardware MPI-network The symbol for the MPI network represents the central communications bus which fulfills the following functions: The CPUs of all stations of a project are loaded and are commissioned with the test functions of the CFC. Communications between stations and display units. Station The symbol for a station represents the hardware structure of a station. If you highlight a station in the lefthand section of the project window, you will see the objects it contains in the righthand section of the project window: Newly inserted stations only contain the "Hardware" object, which you can use to start the tool to configure the hardware. In already configured stations, the programmable modules (CPUs) are also displayed, which were inserted when configuring the station. In Fig. Project window, the configured SIMATIC TDC station is shown as an example; this involves a hardware structure (subrack with slots) which contains a CPU, designated "D01_P1". Hardware By double clicking on the "Hardware" object in a station, you can start the tool to configure the hardware. This procedure is described in detail in the Chapter "Configuring and parameterizing modules" Components to generate software Programs Contents of a program The programs are containers for the software of a CPU and serve as starting point when generating software. A program contains a "Charts" container. As many CFC/SFC charts as required are stored in this container. The CPU program is generated using these. A CFC chart is represented on 26 sub-charts - each with six pages. STEP 7 option packages for D7-SYS - SIMATIC D7-SYS 1-13

25 Basic software Fig. 1-6 Possible components in a program Read further... You were able to get to know the essential objects of a project up to this section of the Chapter. The next section provides you with information about some of the basic activities and handling in conjunction with objects Operator handling philosophy Goal: Simple handling The graphic user interface is intended to make all operator actions selfexplanatory. Thus, you will see objects which you know from your daily work, e. g. stations, modules, programs. The actions, which you execute when working with STEP 7, include the generation, selection and manipulation of objects such as these. Difference to tooloriented handling With conventional tool-oriented handling, you first have to consider which tool was required to solve a specific task, and then you had to call-up this tool. The basic procedure for object-oriented handling is to consider which object is to be edited, and then to open and edit this object. For object-oriented handling, it is no longer necessary to know a special command syntax. Objects are represented on the screen using graphic symbols, which can be opened using menu commands or the mouse. When opening an object, the suitable software components are automatically called which are then used to display or process the contents of the object. Read further... The basic actions when processing objects are now described in the following. Please get to know these, as they are often used STEP 7 option packages for D7-SYS - SIMATIC D7-SYS

26 Basic software Creating and manipulating objects Overview The usual object handling involves: creating an object, selecting an object, executing actions with the object (e. g. copying, deleting). Setting-up the save path for new projects Create objects Opening objects Before first setting-up a new project, you should set the save path for these objects. To realize this, select the menu command Options > Settings. You can then specify a path name under the tab " General " of the dialog box which is displayed, under which the newly-generated projects can be saved. C:\Siemens\STEP7\S7proj. is the default path. You can generate new projects using the menu command File > New > Project. Projects form the top of an object hierarchy tree. All additional objects of the hierarchy, if they are not automatically set-up, can be generated via commands in the Insert menu. The modules of a station are the exception, which are only set-up when configuring the hardware. There are several ways of opening an already generated object: click twice on the object symbol select the object and menu command Edit > Open object After an object has been opened, you can generate or change its contents. In this case, a differentiation must be made between containers, i. e. objects, which can themselves contain sub-objects (for example, a "Directory" object in Windows Explorer, which in turn can contain sub-directories and files), and objects which do not contain any sub-objects, (for example, a "File" object in Windows Explorer). If you open an object associated with the latter type, its contents are displayed in a new window for editing using a suitable software component. Objects, whose contents are being used elsewhere, cannot be changed. Create an object hierarchy After a container has been opened, the objects already contained in the container are displayed on the screen. You can now set-up additional sub-objects using the Insert menu, for example, other stations in a project. Only the commands to insert such objects can be called-up in this menu, which are permissible in the current container. STEP 7 option packages for D7-SYS - SIMATIC D7-SYS 1-15

27 Basic software Setting object properties Object properties are object data, which define the objects behavior. The dialog box to set the object properties is displayed automatically if you generate an object for the first time, and you must define its properties. However, the properties can be subsequently changed: A dialog box is called-up with the menu command Edit > Object properties, in which the properties of the selected object can be read or set. Cutting-out, copying, inserting You can cut-out, copy, insert or delete most of the objects just the same as under Windows. The associated menu commands are provided in the Edit menu. You can also shift or copy objects using drag & drop. The cursor is displayed as a prohibit symbol if you point to an illegal destination/target. If you copy an object, the complete hierarchy below it is also copied. This allows parts of an automation solution to be re-used. Printing First open the object to display the contents. The print command is located in the first window menu (e. g. in the "File" menu). The command displays a dialog box where you can set the printer, printer range and the number of copies to be printed. For several dialog boxes, it is possible to print-out part of its contents. These dialog boxes contain a "Print" button. Press the button to start printing. Re-naming objects You can directly edit or change object names which can be changed via the object properties. Direct editing: If you slowly click twice on the name of a marked object, a box appears around the text. You can now change the name from your keyboard. Changing the name via the object properties: Select the required object, and then enter the menu command Edit > Object properties. Change the name in the dialog box. After closing the properties dialog box, the object is re-named, and displayed with the new name. If it is not permissible to change the name of an object, the input field in the dialog box has a grey background, the actual name is displayed, and it is not possible to enter text STEP 7 option packages for D7-SYS - SIMATIC D7-SYS

28 Basic software Selecting objects in the dialog box Overview Calling-up the dialog box Dialog box structure Selecting objects in a dialog box is something which is done in various operating steps.

29 Basic software 1.4 Creating and handling projects Overview This Chapter describes how you create projects and set-up the project structure step-by-step Creating projects Project example You can simplify creating a new project by adapting the example included in the scope of supply (project example) to your particular requirements. Proceed as follows: 1. Open the project example (refer to STEP 7 projects and basic handling) 2. Save the project example under another name (menu command, File > Save under... ). 3. Now close the project example; open the copy. 4. Change the name of the sub-objects in this copy so that you can identify the names. 5. Open the objects in the copy and modify the contents. This is an extremely easy way to create a project structure. New project Alternative procedure If the project example is not suitable for you as the starting point, then you can create a new project in the SIMATIC Manager by entering the menu command File > New > Project... Now open the project so that you can create the project structure (project hierarchy). When selecting the processing sequence of a project, you have a high level of flexibility. After you have created a project, for example you can first configure the hardware (stations) and then generate the software for it (CFC charts), or Alternative 1: First configuring the hardware Alternative 2: First generating the software you can start to generate the software independently of a configured hardware. If you first wish to configure the hardware, proceed as described in Chapter "Creating and handling projects" > "Inserting and configuring stations". After configuring, the programs and chart containers which are required to generate the software are already inserted. You can then generate the software for the programmable modules. You can generate the software without first configuring the hardware which can then be realized later. The hardware structure of a particular station does not have to be defined before entering programs. Proceed as follows: 1-18 STEP 7 option packages for D7-SYS - SIMATIC D7-SYS

30 Basic software 1. Enter the required software container (programs) into your project (refer to the Chapter "Creating and handling projects" > "Programs with and without assigned hardware"). 2. Then generate the CFC charts in the chart containers of the programs. 3. Now configure your hardware. 4. Now allocate the program to a CPU after you have configured the hardware. NOTE You can call-up a dialog box using the menu command Options > Settings. Under the "General" tab, you can select, among other things, that when a project is opened, an archive of this project is generated as back-up copy. In this case, select the entry "Archiving automatically when opening project/library" (archiving is described in Chapter "Archiving user programs") Inserting and configuring stations Overview Inserting a station In a project, the stations represent the hardware structure and the associated data to configure and parameterize individual modules. In order to create a new station in a project, open the project so that the project window is displayed (if this already hasn t been done). 1. Select the object. 2. Generate the object for the required hardware using the menu command Insert > Station. The following items are displayed in the menu: SIMATIC TDC/SIMADYN D station SIMATIC 300 station SIMATIC 400 station SIMATIC H-Station SIMATIC PC-Station PC/PG SIMATIC S5 Other stations, i. e. not SIMATIC S7/M7, SIMATIC S5 3. Select the station 4. In the project window, click on the "+" in front of the project icon if it is still not displayed below the station. STEP 7 option packages for D7-SYS - SIMATIC D7-SYS 1-19

31 Basic software Configuring Configuring result Proceed as follows: 1. Open the station. It contains the "Hardware" object. 2. Open the "Hardware" object. The "HWConfig" window is displayed. In this window, you can define the hardware structure, and especially the slot assignment. 3. Define the station structure in the "HWConfig" window. A module catalog is available which you can display using the menu command View > Catalog if it hasn t already been displayed. First select a rack from the module catalog. You can then select the modules which you wish to insert in the rack slots. It is important to note that you must configure at least one CPU. Further information on configuring is provided in the Chapter "Configuring and parameterizing the hardware" of this Manual. A program is automatically created as software container for each CPU which you created when configuring. If this object is still not visible in the project window, click on the "+" in front of the station symbol in the project window to display the module, and in the box in front of the CPU to display the program. Continue with software generation Now generate the software. The basic procedure is explained in the Chapter "Principle procedure when generating software". If you wish to use software which was generated independently of your particular configuration, then first read the Chapter " programs with and without assigned hardware" and "Software generation without configured hardware" Programs with and without assigned hardware Overview The " program" object is used as container for the software of programmable modules from the SIMATIC TDC/SIMADYN D spectrum and the FM DP..

32 Basic software Program with assigned hardware Program without assigned hardware You can use the programs which were automatically created for preconfigured (assigned programs). Click on the "+" in front of the CPU icon in the project window if this was still not displayed below the program. You can create programs yourself independently of any special hardware configuration (non-assigned programs). After the hardware has been configured, you can, at a later date, assign a CPU Generating software without configured hardware Inserting the program independently of the hardware Assigning a program to a CPU The project must have been created and the project window opened. 1. Select the project symbol in the project window. 2. Call-up the menu command Insert > Program > D7-SYS Program The program is created below the project, i. e. it is not assigned to any special hardware. You can now generate software in this container, and assign it to a CPU, as subsequently described. Proceed as follows: 1. Highlight the project icon or click on the plus symbol in front of the project icon so that the assigned program is visible in the project window if this isn t already the case. 2. Cut-out the non-assigned program or copy it (menu command Edit > Cut-out or Edit > Copy). 3. Then highlight the CPU which you wish to assign to the program, and insert it (menu command Edit > Insert). If there is already a program located there, then it is overwritten after a message is acknowledged. Alternatively, you can highlight the nonassigned program, and transfer it to the programmable module. Buffering programs in the project If you erase a CPU, but you still wish to keep the associated program in the project, then before erasing the module, shift it directly under the project icon. It then remains there in the project without being assigned to a module. You can assign it as required at a later time. If you erase a station, whose CPUs are assigned to a program, a dialog box is displayed. You can now decide as to whether the program should also be erased (deleted), or whether it should be saved in the project (without assigned hardware).

33 Basic software Principle procedure when generating software NOTE Using the menu command Insert > Program > D7-SYS program, you can create a program directly under the project without having to first configure the hardware. You can later assign the program to a CPU. Procedure Generating the documentation Generate the software as follows: 1. Open the program. 2. Open the "Charts" container contained in it. 3. Insert a CFC chart. The menu command is as follows: Insert > S7 software > CFC 4. Open the chart, insert the blocks in this, interconnect and parameterize these. Information on this procedure is provided in the Manual: "STEP 7, Optionspakete für D7-SYS, Section CFC" as well as online help for CFC. To document a STEP 7 project, you can arrange all configured data, which was generated using STEP 7, in circuit manuals (menu command Insert > Project documentation). This function is only available if the DOCPRO option package is installed Saving projects Overview Saving under... To save a project, you can save a copy of the project under a different name, or archive the project. Proceed as follows: 1. Open the project. 2. Select the menu command File > Save under. The "Save project under" dialog box is then displayed. 3. At " Path " select the directory in which the project is to be saved. 4. In the "Name" box enter a file name. 5. Close the dialog box with "OK". Archiving NOTE It must be guaranteed that there is sufficient memory space still available on the selected drive. For instance, it is not practical to select a floppy disk drive to archive a project. To save projects on floppy disks, you must archive these. Archives can be distributed over several floppy disks. Individual projects can be saved in an archive file in a "zipped" form. It is possible to save "zipped" files on the hard disk or on other portable data mediums (floppy disks) STEP 7 option packages for D7-SYS - SIMATIC D7-SYS

34 Basic software In order to access components of an archived project, the project must first be de-archived. Archiving is described in detail in the Chapter "Archiving user programs". Automatic archiving You can set the system, so that when a project is opened, an archive of this project is generated as back-up copy. Proceed as follows: 1. In the SIMATIC Manager, select the menu command Options > Settings. A register dialog is now displayed. 2. Select the "General" tab. 3. Mark the "Archiving automatically when opening project/library" entry. 4. Close the dialog box with "OK". STEP 7 option packages for D7-SYS - SIMATIC D7-SYS 1-23

35 Basic software 1.5 Configuring and parameterizing modules Overview When configuring with STEP 7, you define which modules you will use for your system, independent of whether they actually exist for your particular system or not Creating a configuration You can copy the configuration as often as you like in other STEP 7 projects, and if required modify them. When a station runs-up, the CPUs compare the reference configuration, generated using STEP 7, with the actual configuration of the system. If errors or problems are present, they are immediately identified and signaled. When parameterizing, you set the characteristics of the modules. You do not have to actuate a switch on the module, but just simply enter the parameter using STEP 7. The parameters are loaded into the CPU, and transferred from the CPU to the appropriate modules. Modules can be very simply replaced, as the parameters, generated using STEP 7, are automatically loaded in the new module at run-up. Introduction Configuring Parameterization The following provides you with an overview how you configure the structure of a station, and how to parameterize the modules within this structure. "Configuring" involves locating racks and modules in a station window. Racks are represented using a configuration table, which permits a fixed number of plug-in modules just like the "real" racks. "Parameterization" is the following: Setting parameters for modules which can be parameterized, e. g. a CPU is a module which can be parameterized. The base sampling time is a parameter which you can set. Procedure Proceed as follows when configuring and parameterizing a system structure: 1-24 STEP 7 option packages for D7-SYS - SIMATIC D7-SYS

36 Basic software Select the rack Select the modules Parameterize the modules Check the consistency of the configuration Save the configuration Fig. 1-9 Procedure when configuring and parameterizing Before entering a new configuration... Before you enter a new configuration, you must: create a project, generated in the project the object to be configured, i. e. a station, and you must have selected this station. The procedure is described in the Chapter "Creating projects". Calling-up the application To call-up the application to configure a station, proceed as follows: 1. Select the "station" object in the project window. 2. Select the menu command Edit > Open Object. The HWConfig user interface is displayed on the screen to configure the hardware. As an alternative to steps 1. and 2. you can also click twice on the "Hardware" object in the station General handling Main components of the user interface You have two dialog windows available to configure an automation system. With the station window, in which you locate the rack for the station configuration. With the "Hardware Catalog" window, from which you can select the necessary hardware components, e. g. racks, modules and submodules. STEP 7 option packages for D7-SYS - SIMATIC D7-SYS 1-25

37 Basic software General handling If the "Hardware Catalog" window is not displayed, select the menu command View > Catalog. You can now display or cancel the Hardware Catalog using this menu command. Independent of a particular station structure, you always configure in the following steps: 1. To open the sub-directory, click on the "+" symbol in the directory listing of the Hardware Catalog. This is how it s done 2. Mark a hardware component in the "Hardware Catalog" window. 3. Place the selected hardware component in the station window using drag & drop. The "Arrange rack" display shows the essential handling: Fig Rack layout 1-26 STEP 7 option packages for D7-SYS - SIMATIC D7-SYS

38 Basic software Summary As for Windows applications, you can implement the overall configuration in STEP 7 per drag & drop. This example will show you what you must be aware of Example Procedure Converting into a configuration table Exactly as you would in your real system, locate the modules in the racks using STEP 7. The difference: In STEP 7, racks are represented using "Configuration tables", which have as many lines as the number of modules which can be inserted in the real racks. An example for converting a real structure into the configuration table is shown in an example in the following Fig Configuration table (normal view) SR PM5 1.1 MS5 2 MM3 3 EB11 4 PM6 4.1 MS5 5 IT41 6 CS7 6.1 SS52-MPI Slot Structure of a SIMADYN D station Fig From a structure to a configuration table Arranging modules Select and arrange racks Prerequisite: The station window and "Hardware catalog" window are open. Proceed as follows: 1. Select the right rack for your particular structure from the sub-directory "racks" in the "Hardware catalog" window. 2. Locate the rack in the station window using drag & drop. As an alternative to steps 1. and 2., you can also click twice on the rack in the "Hardware catalog" window. STEP 7 option packages for D7-SYS - SIMATIC D7-SYS 1-27

39 Basic software Select and arrange modules Proceed as follows to locate modules in the racks: 1. Select a module from the "Hardware catalog" window. 2. Place the module into the appropriate rack tier per drag & drop. As an alternative to steps 1. and 2., you can also mark an empty tier, and then double click on the module in the "Hardware catalog" window or mark a module and hit the ENTER KEY Parameterizing modules Parameterizing Prerequisite You can set the characteristics of modules which can be parameterized. The module type defines which parameters can be set. Before you parameterize a module, you must first place the module in the rack. To parameterize a module, proceed as follows: Parameterizing modules Allocating I/O addresses Double-click on the rack tier with the module, whose parameters you wish to set, or mark the associated module and select the menu command Edit > Object Properties. A dialog box is displayed with one or several registers with information and parameters which can be set for the particular module. You assign module hardware addresses as follows: 1. In the configuration table, click on a module, which has process signal I/O, e. g. a CPU-, I/O- or extension module. 2. Select the menu command Edit > Object Properties and select the "Addresses" tab in the dialog box "Properties". 3. Enter a name for each module connector in the "Symbol" field and acknowledge with "OK". You can change the symbols about the control button To "preset" also with unambiguous names preset. NOTE Assign unique names within any one station. You can obtain help information for an active tab if you press F1 with the "Properties" dialog box open STEP 7 option packages for D7-SYS - SIMATIC D7-SYS

40 Basic software Linking-in hardware signals to the user program Prerequisite Procedure in CFC Prior to this, you must have assigned I/O addresses (hardware addresses) to the module in HWConfig. Link-in the hardware signals to the user program in the CFC as follows: 1. In the CFC, configure an appropriate I/O block to address the hardware signals of a connector. 2. Select the "AD" input (hardware address) of this block, and select the menu command Insert > Connect to operand. A dialog box opens to enter the hardware address. 3. Select the connector name, defined in HWConfig, in the "Hardware address" list field and acknowledge with "OK" Consistency check, saving and loading Introduction Configuration save, In this Section you will get to know how to check and save a generated configuration for consistency. However a prerequisite is that the station is parameterized and configured. To save the configuration use the following menu command Station > Save or Station > Save and compile. For Station > Save and compile, the configuration is checked for consistency, and saved in the current project (as station object). A consistency check is not made for Station > Save. NOTE Configuration load Consistency check CPU charts for this particular station can only be compiled in the CFC, if the saved hardware configuration has been checked for consistency. In CFC, the hardware configuration is, together with the compiled user program, automatically loaded in the CPUs of the station. You check the consistency using the menu command Station > Check consistency. If the configuration is error-free, acknowledge the message "No error" with "OK". If the configuration is not error-free, a message appears with a list of errors. Hit the F1 key to obtain help for the "Check consistency" dialog box.

52 Basic software 1.9 Diagnostics Overview Diagnostics includes the identification, evaluation and signaling of diagnostic events, which occur within the SIMATIC TDC/SIMADYN D control system. In this case, there is a diagnostics buffer in every CPU, in which detailed information can be entered on all of the diagnostic events. For the diagnostics, evaluate the following information, saved in the CPU: Information about the module status Information about the operating status of a CPU By interpreting this information, you can quickly identify, localize and resolve faults and errors. You also significantly reduce the standstill times which occur when a fault/error condition develops. Diagnostic functionality You have the following diagnostic functionality: Call-up the module information from the SIMATIC Manager in the Offline project view Call-up the module information from the CFC Display the value at connection YTS for communication blocks Display the type of diagnostics event via the 7-segment display on the front panel of the particular CPU module Additional information Refer to the "Hardware" Manual for the seven-segment display of the CPU modules.

64 CFC 2.1 Working with the CFC editor This Chapter provides you with system-specific information about CFC (Continuous Function Chart)and how it is embedded in the STEP 7 software package. It also describes the mode of operation of the CFC editor, if this wasn t previously discussed in the Manual "CFC for S7" CFC in the STEP 7 environment How CFC is embedded Fig. 2-1 shows how the CFC is embedded in the STEP 7 environment: SIMATIC Manager STEP 7 components STEP 7 CFC SIMATIC TDC/ SIMADYN D Fig. 2-1: CFC in the STEP 7 environment STEP 7 components Software requirements The following STEP 7 components are of significance when working with CFC for the option package D7-SYS. SIMATIC Manager The SIMATIC Manager administers tools and data. It also sets-up and changes a project structure (SIMATIC TDC/SIMADYN D-/SIMATIC 400 stations, D7-SYS programs, CFC-/SFC charts and starts the CFC/SFC editor as well as compiles charts. HWConfig You can configure the hardware configuration of a SIMATIC TDC/SIMADYN D station or SIMATIC 400 station with FM DP using HWConfig. Using CFC, you refer to the properties of the configured modules, for instance, names of hardware. The operating system Windows 95, 98, ME, NT 4.0, 2000 or XP and the STEP 7 basis software must be installed. For CFC, you require different software option packages depending on the target system. Prerequisites 2-2 STEP 7 option packages for D7-SYS - SIMATIC D7-SYS

65 CFC With the CFC for SIMATIC TDC/SIMADYN D and FM DP you require the D7-SYS option package. With D7-SYS, you are provided block libraries for SIMATIC TDC/SIMADYN D and FM DP which are available in CFC. Installation for SYMADYN D The following diagram shows the inter-dependencies of the CFC software: S7 M7 CFC SIMATIC TDC / SIMADYN D SCL Borland C / C++ M7-SYS STEP7 D7-SYS Fig. 2-2: Inter-dependencies of the CFC software in the STEP7 system environment STEP 7 option packages for D7-SYS - SIMATIC D7-SYS 2-3

66 CFC Project planning data flow data flow The following diagram shows the project planning data flow in SIMATIC TDC/SIMADYN D and the FM DP, starting from importing block type up to loading the machine code into the target system. CFC Editor Block types Block instances Type CFC charts Parameters Generate code C sources Compile and link Compile SIMADYN D operating system SIMADYN D block libraries User program *.BR3 Load SIMATIC TDC / SIMADYN D target system Machine code... Sequence Fig. 2-3: Project planning data flow Description of the SIMADYN D data flow The data flow for the user program of a SIMATIC TDC/SIMADYN D- CPU or the FM DP application module is as follows: 1. The block types of the standard block library "FBSLIB" of SIMADYN D are already included in a newly created chart container. When required, the user can import the necessary supplementary libraries. 2. The CFC Editor is used to create charts by inserting blocks (from the block libraries), and then parameterizing and inter-connecting them. 2-4 STEP 7 option packages for D7-SYS - SIMATIC D7-SYS

67 CFC Handling block types 3. The CFC charts are compiled; a user program is generated which can be loaded. When compiling, the hardware configuration data of the CPU, configured in HWConfig, are transferred into the user program. 4. The user program (and if necessary, the operating system) is downloaded into the target system. In this section, you will see how you import block types and insert them in the CFC chart. Importing block libraries Inserting block types Deleting block libraries The function blocks are organized in block libraries. You import and delete all block types of a library together. Within a library, blocks are grouped into block families, which include blocks which have associated or similar functionality Importing SIMADYN D block libraries Standard block library Procedure The function blocks of the standard function block library "FBSLIB" are already imported in a newly created chart container of a D7-SYS program. When required, additional block libraries can be imported and are then available in all charts of the chart container. This is how you import block libraries: 1. Open a chart of the chart container and select the menu item Options > Block types. A dialog box opens with two windows. The block libraries, installed on your generating system, are listed in the lefthand window "Existing libraries". The libraries, which have already been imported into this chart container, are listed in the righthand window "Imported libraries". Tests 2. In the lefthand window, select the library to be imported, and click on the "Import" button. The selected library is then imported and a dialog box opens and shows you how the operation is progressing. The following test is executed when importing a block library: A check is made as to whether the library to be imported contains a block type which was already imported with another library. STEP 7 option packages for D7-SYS - SIMATIC D7-SYS 2-5

68 CFC Error report If an error is identified when a library is being imported, an error report is displayed with information on the cause of the error. Select an error line of the report and click on the "Help text" button to obtain further information regarding the error cause and how it can be resolved Inserting block types The chart is open. You will find directories of the block families as well as the directories "All blocks" (contains all blocks) and "Other blocks" (for blocks which are not assigned to a particular family), in the block catalog. An icon for free text is shown above the directories. Insert the text field just the same as for a block. Inserting You can insert the required block from the open directory by dragging it into the chart Deleting block libraries You can delete block libraries using the function Options > Block types. This function is used for block types which are no longer required in this particular chart. NOTE The standard block library "FBSLIB" cannot be deleted. Procedure This is how you delete block libraries: 1. First ensure that the library which you intend to delete, no longer has block types which are required in the charts of the chart container. 2. Open a chart of the associated chart container and select the menu item Options > Block types. Checks A dialog box is displayed with two windows. The block libraries installed on your generating system are listed in the lefthand window "Existing libraries". The libraries which have already been imported into this chart container are listed in the righthand window "Imported libraries". 3. In the righthand window, select the library to be deleted and click on the "Delete" button. Deletion is started and a dialog box opens to indicate the progress. When deleting a block library, the following checks are made: It is checked as to whether block types, in the library to be deleted, are used in the charts of the current chart container. Error report If an error is identified when deleting a library, an error report is displayed with information on the cause of the error. Select an error line of the report and click on the "Help text" button to obtain additional information on the cause of the error and how it can be resolved. Click on the "Go to" button to jump to the associated function block. 2-6 STEP 7 option packages for D7-SYS - SIMATIC D7-SYS

69 CFC Updating SIMADYN D block libraries Procedure Checks This is how you update the block libraries: 1. Open a chart of the associated chart container and select the menu item Options > Block types. A dialog box is displayed with two windows. The block libraries, installed on your generation system are listed with their version releases in the lefthand window "existing libraries". The libraries, which have already been imported into this chart container, are listed in the righthand window "imported libraries". 2. Using the version releases of the libraries in the lefthand and righthand windows, check for which already imported libraries, a new version has been installed. 3. In the lefthand window, select the library to be updated, and click on the "new version" button. 4. An additional dialog box, which has a security prompt is displayed. Update is initiated if you exit this box by clicking on the "yes" button. A dialog box opens which displays how the update is progressing. When updating a block library, the following checks are made: It is checked as to whether all of the block types which are used are still available in the new library version. A check is made as to whether block types have changed in the new version so that it is no longer possible to implement a fully automatic update. Those positions, which must be manually edited, are listed in the error report. Error report If an error is determined when updating the library, then an error report is displayed with information on the error causes. Select an error line of the report and click on the "help text" button in order to obtain more information on the error cause and how it can be resolved.

70 CFC Editing block inputs The Manual "CFC for S7 describes in detail how you edit block inputs, i.e. change the properties of the inputs Additional properties of the block I/Os In the target system, SIMATIC TDC/SIMADYN D bzw. FM DP, I/O can have additional properties. Scaling factor Values at the outputs Pseudo comments An optional scaling factor can be configured at the I/O of the data type REAL (R), to normalize analog values (define them as per unit values). The scaling factor is pre-assigned the value 1.0. An initialization value can be specified in the "Value" field of the property dialog box at the block outputs. This value is available at the output if the associated block was calculated for the first time in the operating mode INIT. Comments at block I/Os, which start with "@", are pseudo comments and are taken into account when compiling data for the SIMATIC TDC/SIMADYN D bzw. FM DP target system. Pseudo comments influence the user program : The input is connected, bypassing the consistency mechanisms. Connection is a parameter (with range ID "H", "L", "c" or "d" and a three-digit parameter number nnn, e. I/O is a technology connector (identified by a four-digit connector number nnnn, Additional information on pseudocomments, refer to the SIMADYN D User Documentation: "System Software and Communications Configuring D7-SYS" Manual Section "System Software, Sec. Generating CFC Charts" "Communications Communications Configuring D7-SYS" Manual, Section " Communications Configuring " Sec. "Parameter Access Technology for D7-SYS" Inverting inputs It is not possible to invert binary inputs for SIMATIC TDC/SIMADYN D and FM DP (menu item Edit > Invert Input). 2-8 STEP 7 option packages for D7-SYS - SIMATIC D7-SYS

71 CFC The GLOBAL data type Block interconnections I/O of the GLOBAL (GV) data type cannot be interconnected. They must be interconnected with global operands (refer to Section ). The definition and procedure when interconnecting blocks is described in the Manual "CFC for S7". A description of the system-specific properties of the interconnection are now described. Interconnectability of data types For SIMATIC TDC/SIMADYN D and FM DP, not only can I/O of identical types be interconnected, but also: REAL (R) and SDTIME (TS) INT (I) and WORD (W) DINT (DI) and DWORD (DW) The STRING data type The GLOBAL data type I/O of the STRING (S) data type cannot be interconnected, neither to each other nor with global operands. I/O of the GLOBAL (GV) data type cannot be interconnected. They must be interconnected with global operands (refer to Section ). GLOBAL I/O which are not connected are flagged as erroneous during the consistency check or when compiling Interconnecting to global operands Definition Global operands are connection partners which are located outside the CFC charts. For SIMATIC TDC/SIMADYN D und FM DP, communication aspects as well as linking input/output blocks to hardware addresses are configured as interconnections to global operands. Special feature Types of global operands For nested charts all connections to global operands must be routed to the chart interface. This avoids global operates being defined a multiple number of times (e.g. $ signals are created a multiple number of times). For SIMATIC TDC/SIMADYN D und FM DP, a differentiation is made between the following types of global operands: $ signals virtual connections virtual connection names OP connections hardware addresses STEP 7 option packages for D7-SYS - SIMATIC D7-SYS 2-9

72 CFC module names name references process interrupts Entry dialog boxes Select the block I/O which is to be connected with a global operand and select the menu command Insert > Connection to operand. Depending on the block I/O type, CFC opens an appropriate dialog box. Selection lists in the dialog boxes offer practical entries depending on the particular context. Further, you can directly enter a name in the dialog box input field. You can change the name of a $ signal after you have double-clicked on the name in the margin. Entry syntax Help When entering names, the syntax for the particular global operand type must be observed (refer to Table 2-6 Name lengths). To obtain information on what you can enter, depress F1 with the entry dialog box open $ signals For further information, refer to the help for the function blocks to be interconnected. To access this help, select the block in the chart and then depress F1. Block I/O $ signals can be configured at all inputs and outputs with the exception of STRING (S) and GLOBAL (GV) data types. They are used to simply configure interconnections between blocks on different CPUs within a SIMADYN D station. Additional information on configuring $ signals, refer to the Manual "System Software and Configuring D7-SYS". Bus and type Contents of the selection list If you "create" a $ signal, i. e. you configure it at a block output, you can define whether the signal is transferred via the L- or C bus of the subrack, and which type it is (Standard or Fast). The selection list shows you the already configured $ signals configured at other CPUs of the SIMADYN D station with which the I/O can be connected: At block outputs, these are all data types, which match $ signals which are used at block inputs of other CPUs, but which still haven t been created. At block inputs, these are all data types which match $ signals and which are created at the block outputs of the other CPUs STEP 7 option packages for D7-SYS - SIMATIC D7-SYS

73 CFC Interconnectability of data types Using $ signals, not only can I/O of the same type be connected, but also: REAL (R) and SDTIME (TS) INT (I) and WORD (W) Virtual connections DINT (DI) and DWORD (DW) Block I/O Virtual connections can be configured at all I/O with the exception of those of STRING (S) and GLOBAL (GV) data types. They are used to configure communication connections via the "Process data" utility. Additional information on configuring virtual connections, refer to the Manual "System- and communication configuring D7-SYS". Virtual connection name Sequence number Contents of the selection list By specifying a virtual connection name, you establish a reference to a transmitter or receiver which transfers the net data of this particular connection.

Run-time groups are optional. They are used to structure and sub-divide tasks. The blocks are sequentially inserted in the individual run-time groups. A run-time group is enabled and disabled via run-time attributes. Order in which the tasks are executed The following is valid for the tasks: The sequence of groups and blocks inserted within a task, is the run sequence. The same is true for groups: The sequence in which the individual blocks are inserted is the run sequence within the group. You can change the order of execution. Blocks are not inserted a multiple number of times In the SIMATIC TDC/SIMADYN D target system, and for the FM DP, each block must be inserted precisely once. It is not permissible to insert blocks a multiple number of times in several tasks Run-time attributes A run-time group has the following three attributes in the CFC: Enable Scan rate (not permissible for SIMATIC TDC/SIMADYN D and FM DP) Phase offset (not permissible for SIMATIC TDC/SIMADYN D and FM DP) The group inherits these attributes in all of the blocks which it contains. The attributes are assigned when creating the run-time group. The enable attribute can be controlled via an interconnection. Scan and phase offset not possible Enable attribute In the SIMATIC TDC/SIMADYN D and for the FM DP target system it is not possible to specify different scan rates and phase offset of a runtime group. The enable attribute activates or deactivates a group (on=1, off=0). As long as it is set to 0, the group is not executed, irrespective of all of the other conditions. The enable attribute is set to 1 as standard. However, it can also be dynamically set. In this case, the output value of a CFC block determines whether the group is to be activated or de-activated. You can interconnect the binary output of a block with the run-time group for this purpose STEP 7 option packages for D7-SYS - SIMATIC D7-SYS

77 CFC! CAUTION Certain blocks (especially communication blocks) may never be disabled in the RUN operating mode. This means that they cannot be configured in run-time groups, whose enable signal is controlled from a binary output. Please observe the appropriate instructions in the function blocks library Operator control and monitoring CFC offers you a user-friendly method to control and monitor variables of your process or your automation system using WinCC. The advantage over previous methods is that you no longer have to individually configure data for each operator station (OS), but you only have to do it once in the CFC. You can transfer the data generated when configuring with CFC into the WinCC data administration using the transfer program D7-SYS-OS Engineering (this belongs to the "D7-SYS" software package). Data consistency and compatibility with the display system is also checked. WinCC uses the data in the display blocks and graphic objects For SIMATIC TDC/SIMADYN D, you can configure and change the operator control and monitoring attributes for the block connections (I/O). Principle procedure Name syntax When configuring variables which can be controlled and monitored, proceed as follows: 1. Assign the I/O, which you wish to control and monitor, with the necessary operator control and monitoring attributes, in a dialog box. These can include limit values, equivalent values and logging characteristics, etc. 2. Transfer the configured software data, generated with CFC, to your display unit (WinCC) using the D7-SYS-OS Engineering. In order that the configured data for WinCC can be saved and transferred, the D7-SYS OS engineering transfer program automatically allocates unique names. These are then saved in WinCC. The name is made up of the following components: SIMATIC TDC/SIMADYN D station name CPU name CFC chart name Block name Block connection (I/O) name The names may not include any underlines, blanks or special characters " ", ".", "%", "-", "/", "*", "+". STEP 7 option packages for D7-SYS - SIMATIC D7-SYS 2-15

78 CFC Configuring operator control and monitoring attributes In WinCC, each Operator Control and Monitoring-capable connection (I/O) of a block which has been activated for operator control and monitoring, can be accessed. Data transfer is always realized using an instance DB. When configuring, this is automatically assigned to the operator control and monitoring attributes in the CFC. Procedure Proceed as follows when configuring operator control and monitoring attributes of operator control and monitoring-capable connections: 1. Select the block. 2. Select the menu command Edit > Object properties. 3. Activate the "Operator C and M possible" control box in the "special object properties" area 4. Click on the "Operator Control and Monitoring" button. This allocates an instance DB to the block. The instance DB is used to establish communications with the WinCC. 5. You can now enter or change the operator control and monitoring attribute values in the "Operator Control and Monitoring" dialog box. NOTE You can obtain additional help by pressing the F1 key with the "Operator Control and Monitoring" dialog box open Compiling and loading 6. Close the dialog box by clicking on the OK button. Please observe the following when configuring: It is not possible to make I/O operator control and monitoring capable with CFC in the online mode. If a new I/O for operator control and monitoring using WinCC is required, the program must always be newly compiled and loaded! I/O of block-type structures, which were generated in the CFC using nested charts, are not operator control and monitoring-capable! The next two sections describe the following: Compiling the user program Loading the user program 2-16 STEP 7 option packages for D7-SYS - SIMATIC D7-SYS

79 CFC Compiling the user program Interrelationships When compiling the charts for a SIMATIC TDC/SIMADYN D-CPU or an FM DP, observe the following: All of the charts of the chart container of a CPU or the FM DP are always compiled in the CFC together with a user program, which can be loaded and run. In this case, all of the block types used are automatically linked-in. Thus, for the SIMATIC TDC/SIMADYN D target system and FM DP, it is not necessary to separately compile and load. The hardware configuration of the SIMADYN D station, in which the CPU is inserted, is also included in the user program. Thus, it is not necessary to separately compile and load the hardware configuration for a SIMATIC TDC/SIMADYN D target system and FM DP. When compiling, the resources of a SIMATIC TDC/SIMADYN D-CPU and a FM DP CPU are automatically assigned. It is not necessary to make manual interventions to the resource management. The cross-compilers required are invisible to the user and are calledup by the CFC. The CFC already identifies any configuring errors. You don t have to know anything about the cross-compiler. Prerequisites Compiling Compilation scope Before you can compile the charts of a SIMATIC TDC/SIMADYN D-CPU or a FM DP, the hardware configuration of the station, in which the CPU or FM DP is inserted, must be compiled and saved. You start chart compilation by entering Chart > Compile > Charts as program; acknowledge the dialog box using "OK". Compilation is initiated and a dialog box is opened where you can see how compilation is progressing. When compiling, you can select one of two possibilities: Scope: Only compile changes Only those parts of the chart container are compiled, which have been changed since the last compilation. Thus, when re-compiling, compilation times can be reduced by approximately 25%. Note: Even if you only compile changes, all of the charts of the chart container are checked for consistency (consistency check). Scope: Compile everything The complete contents of the chart container are compiled, independent of whether the configured software has been changed since the last compilation. STEP 7 option packages for D7-SYS - SIMATIC D7-SYS 2-17

80 CFC After compilation Settings for compilation 1. When compilation has been completed, you will see a display of the number of errors and warnings which have been identified. You can open a detailed compilation report using the "Details" button. 2. Select an error line of the report and click on the "Help text" button to obtain more detailed information about the cause of the error and how it can be resolved. Click on the "Go to" button to jump to the associated function block. 3. You can call-up the report at a later time using the menu command Options > Report; if required you can also print these reports. You can make several settings before compiling: You can call-up a dialog box using the menu item Options > Settings > Compilation. This allows you to make the following settings: Which directory should be used to save temporary files which are created during compilation? e.g. Default: c:\temp Should an address book be created, yes or no? NOTE If you activate this option, when compiling, it is guaranteed that the name syntax of STRUC Version 4.2 is maintained for chart, block and $ signal names for SIMADYN D This note only refers to SIMADYN D. Should a map listing of the user program be created, yes or no? Which function block types are to be inserted online in the test mode of the CFC: only already configured block types the block types in the "FBSLIB" standard library block types from all of the imported libraries Is system data (operating system and block libraries) to be taken from the D7-SYS installation or from the archive (path) in the present configured software? This means that it is possible to edit older configured software with the matching system data without having to adapt the version. Should a file be created in which the data of all connections (I/O) or only the string connections are to be entered? The appropriate box can be marked under "Create file for:". Multi-processing and compilation It must be ensured that the user programs of all CPUs of a station are consistent with respect to one another to guarantee that all of the CPUs of a SIMATIC TDC/SIMADYN D station run-up and operate together in a coordinated fashion. When compiling the user program, a CPU is checked, with reference to $ signals as to whether there are anyinconsistencies with the user programs of the other CPUs in the station STEP 7 option packages for D7-SYS - SIMATIC D7-SYS

81 CFC NOTE Inconsistencies can occur if you make changes to the configured data within a station, after you have already compiled the individual CPUs Loading the user program After which configuring changes do you have to re-compile a user program? If you changed the charts of this CPU. If you changed the station hardware configuration. In this case, you should re-compile the user program of all CPUs in the station. If you removed or changed the name of $ signals at the block outputs. In this case, all of the CPUs, which use the $ signal, are used. If you are not certain whether the user program of a CPU must be recompiled, then check it using the "Only compile changes" option. If the user program does not have to be re-compiled, then the CFC will flag this and will interrupt compilation. In order to use a user program on a CPU or FM DP, it must first be loaded. The user program, compiled from the charts of the CPU or FM DP, is loaded into that CPU or FM DP which is assigned to the active chart window. The user program is transferred into the CPU or FM DP program memory, but is however still not active. The new user program is activated if the CPU or FM DP is restarted (also refer to Section 2.3.1). You can either load the user program offline or online. Offline loading Online loading Remove the memory module from the CPU or FM DP module, insert it into the appropriate slot of your PG/PC or external programming device (OmniDrive or USB-Prommer) and load it offline. This is only possible for modules, which use a separate memory module (for example, this cannot be used for the T400 technology module). For online loading you connect your PC with an appropriate communications interface of a SIMATIC TDC/SIMADYN D station (DUST1 or MPI) or a SIMATIC CPU/SIMATIC CP for a FM DP (refer to Section ) and load the user program online. Depending on the selected communications connection, you can load the program memory of a CPU/FM DP or all CPUs of a station online. If you have a system-wide MPI bus interface, you can centrally load each CPU of your system without having to get involved with the wiring or hardware of your system. Booting STEP 7 option packages for D7-SYS - SIMATIC D7-SYS 2-19

82 CFC A special procedure is required for the following cases, when loading online via the MPI bus interface: In the boot status (initialization status), i. e. before software is first loaded, all of the program memories have the same software. Initially, all stations have the same address, as the addresses of the stations on the MPI bus are only defined after the user program has been loaded. In order to establish unique addresses, the stations which you do not want to load data in, must be disconnected from the bus or powered-down. You can switch-in another station after loading the programs of the stations and transferring the new programs into the working memory (RAM memory) (with a cold restart of the station). CPU addressing within the station does not pose a problem as it is realized, slot-related. If you modify the hardware of a station, i. e. add, remove or changeover modules, the station goes back into the boot status where only reloading is possible; the displays of all of the CPUs of the station have a flashing "O". If you change several stations simultaneously, an address conflict will occur, as in the boot status (initialization status), which must be resolved as described above. Prerequisites The prerequisites and conditions for loading the user program depend on the type of loading technique which will be selected. The following conditions must be fulfilled to load offline: 1. The user program to be loaded has been compiled, error free. 2. The create mode of the CFC is selected. To load the user program online, the following conditions must be fulfilled: 1. A memory module is inserted in the CPU to be loaded. The SIMADYN D operating system is already loaded in this memory module. You can identify this by the fact that, after the power supply is powered-up, the 7-segment display of the CPU has a flashing "0" however, not with a point. 2. There is a communications link between the CPU and your PC 3. The user program to be loaded has been compiled, error-free. 4. The create mode of the CFC is selected. 5. Additional requirements when downloading into a T400-CPU online: Switch S1/8 of the T400 has been switched-out You have established an online connection between the generating system and the T400 (serial interface X01, terminals ). Procedure You can load the user program as follows: 1. Select the menu item PLC > Download STEP 7 option packages for D7-SYS - SIMATIC D7-SYS

83 CFC 2. The "Download" dialog box opens. 3. Define the scope of the software to be downloaded: Generally, it is sufficient to only load the configured software ("Only user program") thus reducing the download time. However, if CFC has identified that the operating system release has changed since the last time that data was loaded into this CPU or FM DP, then the new release of the operating system is automatically downloaded. If software has still not been downloaded into the CPU or FM DP, you must download the complete software ("system and user program"). 4. Specify how the PC can access the program memory: During start-up, generally you will leave the memory module with the user program in the CPU or FM DP and select the "online" option. With "offline" you must remove the memory module from the CPU or FM DP and insert it in the appropriate PCMCIA socket or MMC slot of your PC. 5. To start loading, use the Load function. The CFC responds by showing how loading is progressing. 6. After loading has been completed, you will find the new user program in the CPU or FM DP program memory and this becomes active when re-started (cold restart).

84 CFC 2.2 Brief guide This brief guide is intended for newcomers who have still not had a chance to get up to speed with the CFC program package. We will show you a small example where, after starting the SIMATIC Manager, you can create a project, create a CFC chart, interconnect blocks, compile the chart and load the software into the target system SIMATIC TDC/SIMADYN D or FM DP and then test it online. Comment Generally, there are various ways to achieve a goal. However, in this particular example we only want to show you one, namely the fastest or best way. Alternative procedures will not be discussed here with just a few exceptions The first steps So, you want to create a small application, using the CFC, for the automation system. You are knowledgeable about the Windows interface of the operating system; the STEP 7 software package and the CFC software (including the D7-SYS option package) are already installed. Power-up your PC or PG and wait until the Windows screen appears on your display. Now you can start... Starting On the Windows screen you will see an icon for the SIMATIC Manager, the entry into the STEP 7 software. STEP 7 is started just like a Windows application by double-clicking on the SIMATIC Manager. The SIMATIC Manager window opens and the STEP 7 Assistant is also opened. You must acknowledge the STEP 7 Assistant with "Cancel" STEP 7 option packages for D7-SYS - SIMATIC D7-SYS

85 CFC...the next steps To start-off with, you will create a project. A project allows you to save the data and programs, obtained while creating the project, in an orderly fashion. There is no specified sequence when creating a project, but that you can see for yourself Creating a project Set-up a project structure Firstly, set-up your project structure. Set-up a new project in SIMATIC Manager and open it. You can do this by using the icon in the tool bar: (new project) In the "New" dialog box, select the Path, enter the required Project name (in this case: "auto_ex") and close the box with "OK". The project window appears, split into two fields: The project icon with the project name is shown in the lefthand field and, the contents in the righthand field, which in this case are: The icon and the name of the MPI network. You can now decide whether you first want to set-up the hardware and then the software or vice versa. If you create the software first, then after the hardware configuration, you can assign it to a CPU using drag & drop. Inserting the hardware We start by inserting a SIMATIC TDC/SIMADYN D station in the project. Select the project container and then Insert > Station > "Station name" (Select a SIMATIC TDC station or a SIMADYN D station) The "Station name" icon is inserted. Place the mouse pointer at the selected station icon and depress the right mouse key. Click on Open object... in the menu which is now displayed. The HWConfig application to configure the hardware now opens. If the "Hardware catalog" window is not visible, then open it using the icon: NOTE For more detailed information on configuring the SIMATIC TDC/SIMADYN D hardware, please refer to the section "Configuring and parameterizing modules" in the User Documentation "Basis software for D7-SYS." STEP 7 option packages for D7-SYS - SIMATIC D7-SYS 2-23

86 CFC In SIMATIC Manager you will now see, below the "SIMATIC TDC/SIMADYN D station the icon D01_P1", the CPU module which you just configured. Click on the "D01_P1" icon to open it. You will see, that a D7-SYS program has already been assigned to the CPU. This already contains a chart container "Charts". You will see this when you open the D7-SYS program. Inserting the software If you open the chart container, you will see that it already has a function chart. This is "@SIMD" system chart. Now, insert your first CFC chart: 1. Select the chart container and then, using the right mouse key Insert New Object > CFC 2. Now give the chart a new name. The text field of the CFC name is already selected and the cursor activated. 3. Edit the new name, in this case: "cfc_reg1". Fig. 2-4: Inserting the new CFC chart in the chart container Thus, the project structure has been set-up, and a chart created. Blocks must now be inserted into this chart and interconnected so that a control task can be implemented STEP 7 option packages for D7-SYS - SIMATIC D7-SYS

87 CFC Starting CFC and inserting blocks Preliminary comments Configuring example Before we really get going, we should first briefly discuss what will be configured in this chart. This configuring example involves a basic oscillation circuit, which generates a sinusoidal oscillation at its output. You can create this chart yourself in just a few minutes which you can then run as demonstration in the test mode. You use two block types: 2 integrators (INT) 1 subtractor (SUB). The oscillation circuit (according to the differential equation f"(x) = - f(x) ) is formed using two integrator blocks with feedback via a negation function. The frequency of the oscillation circuit is defined by the integral action time of the integrator. The amplitude of the oscillation is determined by the initial value at the integrator output. Opening the CFC chart By double-clicking on the chart icon, you can open the chart and implicitly start the CFC Editor. The CFC window is opened. The chart window and the block catalog are located in the CFC window. The block catalog can be switched-in and switched-out using the following symbol. (catalog) STEP 7 option packages for D7-SYS - SIMATIC D7-SYS 2-25

88 CFC Block catalog You can position the block catalog anywhere on the screen. Fig. 2-5: Block catalog You can use the blocks of the standard library "FBSLIB", supplied with the system, to configure the CFC chart. Open the "Closed-loop control" family of control blocks. Select the INT block and drag it, with the left mouse key depressed, into the chart. The block outline will be represented as a dotted line. Release the mouse at a suitable position. The block will be displayed in the chart with its real size. Place a second copy of the INT block next to the first. Now you should look for the SUB block. Enter the SUB name (in upper case letters) in the entry field of the block catalog, and click on the "Binocular" icon (field glasses). The search starts and the SUB block is quickly found which is included in the "Arith." family. As before, drag this block to a free location in the chart STEP 7 option packages for D7-SYS - SIMATIC D7-SYS

89 CFC Go into the page view If your chart was displayed as an overview. Click in a free location in the chart using the right mouse key and in the context menu in page view. In this zoomed display you will also see the block connection designations (I/O connections) Interconnecting blocks Interconnecting blocks We now come to interconnecting. Select output "Y" of the lefthand INTegrator and then input "X" of the righthand INTegrator Editing blocks Select output "Y" of the righthand INTegrator and then input "X2" of the SUBtractor. Select output "Y" of the SUBtractor and then input "X" of the lefthand INTegrator. The autorouter has already drawn the connecting lines from the outputs to the inputs; the I/O are interconnected. We will now parameterize the blocks which we interconnected and change the sequence in which they are executed (run sequence). Changing the run sequence Select the menu item Edit > Run sequence... The "Run sequence" dialog box is displayed: You will see the task structure in the lefthand window; the contents are displayed in the righthand window. The default location of the block is in the highest priority cyclic task T1. We now want to shift the block, just inserted from task T1, into the lowerpriority task T3. Double click on the "T1 [cyclic task]" icon. The blocks (including chart/block name, comments and position) are displayed in the righthand window. Select all three of the blocks, and drag these to the cyclic task "T3" icon in the lefthand window. The righthand window is now empty. If you open "T3 [cyclic task]", the three blocks are now displayed there. Close the dialog box with Chart > Close and then proceed to the next step. Parameterizing inputs The limit inputs of the integrators must now be supplied with other values. You can now do this, individually for each input, by double-clicking and calling-up the dialog box "Properties - I/O" or you can take the easier route: STEP 7 option packages for D7-SYS - SIMATIC D7-SYS 2-27

90 CFC Double-click on the lefthand "INT" block. The "Block Properties" dialog box opens and then you can select the "I/O" tab. The parameters in the fields with grey background, cannot be changed. In the table, first go to the "Values" column, and change as follows: LL: LU: TI: From "0.0" to "-10.0" (the lower limit value) From "0.0" to "10.0" (the upper limit value) From "0ms" to "500ms" (the integrating time constant) In the "For test" column, highlight the input, which is later to be monitored in the test: Y. Close the dialog box with "OK". Double-click on the right "INT" block and enter the same value as at the lefthand INT block. Also change the initialization value at the block output: Y: From "0.0" to "10.0" (the initialization value of the output) The block output has this value when the block is first executed The "SUB" block doesn't require any values to be changed. It acts as negation element when it has the default value 0.0 at its input X1. Help for the block types If you require more detailed information on a block, then select it and press F1. Thus, our small example has now been configured and the chart can be compiled and loaded STEP 7 option packages for D7-SYS - SIMATIC D7-SYS

91 CFC Compiling and loading into the target system Compiling The graphically-created chart must now be compiled into the machine code of the SIMADYN D target system. Click on the tool bar: (compile) The "Compile" dialog box is displayed with the following entries: Target system: SIMADYN D CPU: 1 D01_P1 In the "Scope" field, you can now select whether the complete chart container ("Compile everything") or only the changed objects ("Only compile changes") should be re-compiled. In this case, we wish to "Compile everything". Compilation is initiated with "OK". The new dialog box is displayed. The compilation progress is displayed in the new dialog box. Consistency check...after compilation Before actual compilation, the system automatically executes a consistency check. Before compilation, if you wish to check whether compilation makes sense, you can first execute this consistency check with Chart > Consistency > Charts as program. A dialog box with the "Compilation error-free" message is displayed after compilation. Compilation has now been completed and the user program, which can be loaded has been generated. In a next step, you can load the program into a memory module for the SIMADYN D CPU. Insert the memory module in a PC Loading Insert a SIMADYN D memory module into the PCMCIA slot ("socket") No. 1 of your PC or in the OmniDrive (external PC card drive). In the tool bar, click on (load) Select "System and user program" loading as scope in the "Load" dialog box; and, "offline (OmniDrive)" as loading type. Start loading with "Load". The user program and the operating system of the CPU are loaded into the memory module. Starting the CPU Insert the memory module, which was just loaded, into receptacle X01 (module receptacle) of your SIMATIC TDC/SIMADYN D CPU and powerup the subrack. STEP 7 option packages for D7-SYS - SIMATIC D7-SYS 2-29

92 CFC The CPU runs-up and after a few seconds, CPU number "1" appears on the display Monitoring and changing in the test mode Testing the program In the test mode, you can monitor the values of the block connections (block I/O) and you can change the values of the block inputs. The values, registered for test, have a yellow background. You can easily monitor the control characteristics by changing several parameters, for example, how the manipulated value approaches the setpoint and stabilizes. Changing-over into the test mode NOTE Before you change over into the test mode, select the test mode "Laboratory operation" with Test > Laboratory operation. This means that all of the block connections (I/O), registered "for test" will be automatically switched-in for "monitoring". In the process mode no connection is preset for monitoring. In this test mode, you must mark the appropriate blocks and explicitly register them for monitoring. Activating the test mode Activate the CFC test mode: Click on the icon in the tool bar: (Testmodus) or select Test > Test mode In the status line, the text in green "Text: RUN (laboratory)" is displayed. Monitoring Change input value You can now see your oscillation circuit working, i. e. how the values of the connections, selected for the test, change. The values of the I/O have a yellow background. In the test mode you can also change all of the values at the inputs which have not been interconnected. If you want to see how the characteristics change when a value is changed, enter "5000ms" as integration time at the lefthand INT block. Double-click on input "TI". The "Properties - I/O" dialog box opens. Change the value for the block input and acknowledge the new value with "OK". In the chart, you can now see how the "Y" output changes significantly slower as a result of the new input STEP 7 option packages for D7-SYS - SIMATIC D7-SYS

93 CFC Deleting interconnections Select input "X2" of the SUB block and remove the interconnection with Edit > Delete. The interconnections between the output of the righthand integrator and the SUB block is deleted, thus interrupting the oscillation circuit feedback. In the chart, you can now see how the input- and output values of the blocks remain stationary. Re-establishing interconnections Select output "Y" of the righthand INTegrator, using the lefthand mouse key, and then input "X2" of the SUBtractor. The interconnection between the output of the righthand integrator and the SUB block is re-established. In the chart, you can now see how the values start to change again. Insert and delete blocks De-activate test mode In the CFC test mode, you can insert additional function blocks online in the chart and interconnect them with already configured blocks (offline). To return to the create mode, deactivate the test mode. Click on (test mode) The create mode is now re-activated Generating documentation and closing project Complete documentation Chart reference data Your example has been successfully configured and debugged (tested). You can now generate a complete set of documentation for this small example. The chart reference data in this case are the "Cross references block types" and the "Run sequence". On the tool bar click on (Referenzdaten) You can now generate and display the appropriate lists, using the icons in the tool bar in the dialog box "Chart ref: Display chart reference data". You can then print these lists (print) Then close the dialog box with Reference data > Exit. STEP 7 option packages for D7-SYS - SIMATIC D7-SYS 2-31

94 CFC Print chart You also wish to print the chart. Only one page was used on this chart. This is the reason that we recommend the single-sheet print-out. The chart is still set to "Page view". You can now start printing: (print) Close The project has now been completely created; you can now close the CFC Editor with Chart > Close. The CFC window is closed.. You can close the SIMATIC Manager with File > Close The window of the SIMATIC Manager is closed and you return to the Windows screen STEP 7 option packages for D7-SYS - SIMATIC D7-SYS

95 CFC 2.3 Testing and commissioning Before you can commission the complete software structure, you must test its functionality in detail. To support commissioning, functions are integrated in the CFC Editor to monitor values online and to make corrections in the loaded software. These functions are described in this Chapter. Editing modes The CFC Editor has two edit modes: The create mode to configure charts Test mode to test and commission the configured user programs. Menus Function groups The functions of the CFC Editor for commissioning and test are provided in the two menus PLC and Test. With the PLC options, you can display and change the status of the CPU presently being processed. With the options of the Test (debug) menu, you can directly influence the CPU program (at the target software). The functions for test and commissioning can be sub-divided into the following main groups: Functions when preparing for testing are: Loading the user program into the CPU (refer to 2.2.6) Viewing and changing the operating mode Checking that the configured software and CPU program match Changing the refresh rate for monitoring Working in the test mode Display functions for the CPU The CPU supports you for system diagnostics by saving information about errors which have been identified. This is realized without any specific configuring work having to be done. This allows you to quickly identify and remove errors. When a fault condition occurs, standstill times can be significantly reduced. You can obtain information on the system diagnostics using the functions of the PLC > Module information... menus Monitoring and parameterizing block I/O You can monitor the values of all of the block I/O during operation and change the parameter values at the block inputs online. Creating and deleting interconnections: In the automation system you can create or delete interconnections between block I/O online. STEP 7 option packages for D7-SYS - SIMATIC D7-SYS 2-33

96 CFC Inserting and deleting blocks: In the automation system you can insert and delete blocks into the CPU program which is running, online Viewing and changing the operating mode Operating modes A SIMATIC TDC/SIMADYN-D-CPU or an FM DP can have various operating modes: Power off In this mode, the system is not operational (it is powered-down). The seven-segment display and LEDs are dark; communications with the CPU or the FM DP cannot be established. INIT In this mode, the system initializes itself (runs-up). The sevensegment displays indicates "0" or the RUN LED flashes; communications with the CPU or FM DP cannot be established. After this mode, the system goes into the following modes. RUN This is the standard operating mode. The CPU or the FM DP processes the configured user program. The status display shows the CPU number ("1"... "8") or an error code "C", "E", "b" or "A". For an FM DP, the RUN-LED is bright or one of the fault LEDs (CF, TF, MF, UF) is bright. In this mode, the CPU can be accessed online via the local service interface and the configured service interfaces. An FM DP can be accessed, online via the SIMATIC CPU or an appropriate SIMATIC CP. Using the "Cold restart" or "Stop" commands (refer below), it is possible to go into the INIT mode or user stop mode. User stop The CPU or FM 458-1DP only goes into this mode, if an explicit stop command is issued (refer below). A seven-segment display indicates "d" or the STOP LED of the FM DP is bright. for two CPUs: CPU with user stop: "d2 flashes other CPUs: "d" is continuously displayed This mode is used to quickly load the user program into the CPU. Fast means that in this mode, cyclic processing (execution) is stopped, and the complete computational performance of the CPU or FM DP is available for loading (STOP LED flashes for FM DP). Loading can be realized via the local service interface or via the configuring service interfaces for FM DP via SIMATIC CPU or SIMATIC CP. Using the "Cold restart" command (refer below), it is possible to enter the INIT state. STOP due to initialization error The CPU or FM DP goes into this mode, if an error is identified in the INIT mode where it does not make sense to go into the RUN mode. An "O" or the STOP and IF LED of the FM DP are displayed on the 7-segment display. In this state, the local CPU 2-34 STEP 7 option packages for D7-SYS - SIMATIC D7-SYS

97 CFC service interface as well as the initialization interface are available for loading and for fault diagnostics. For an FM DP, the interface of the SIMATIC CPU or a SIMATIC CP can be used. It is possible, to go into the INIT mode by issuing a "Cold restart" (refer below) command. STOP due to system errors The CPU or FM DP goes into this state, if a fatal error was identified in one of the other states, so that the system should not go into another operating state. An "H" or the STOP and INTF-LED of FM DP are displayed on the 7-segment display. In this state, only the local service interface is available for loading and error diagnostics. For the FM DP, in this state, the interface of the SIMATIC CPU or a SIMATIC CP can be used. It is possible to go into the INIT state by issuing the "Cold restart" command (refer below). For SIMADYN D, it is not possible to change thestate of individual CPUs for SIMATIC TDC/SIMADYN D, due to the tight coupling between the CPUs; a mode change always involves the complete station. Prerequisites You can restart the SIMATIC TDC/SIMADYN D station or an FM DP by either issuing a command from the PC, as described in the following, switching the power supply voltage off and then on again or activating the reset signal of the subrack power supply. If you wish to view the operating mode and change it using CFC, then the following conditions must be fulfilled: There must be a communications link between a CPU of the current station and your PC The create mode must be selected for all CPUs. Procedure If you wish to view and change the operating mode using CFC, then proceed as follows: Select the menu item PLC > Operating Mode...; the associated dialog box is displayed. Press the "Cold restart" button if you wish to bring the station into the INIT mode; the "Stop" button, if you wish to change from the RUN into the user stop mode. For SIMATIC TDC/SIMADYN D, the CFC responds with a progress display. After a short time, you can see at the station that the 7- segment displays of all of the CPUs inserted in the station have a new value. For an FM DP, the appropriate change of state is displayed in the same dialog box. The LEDs of the FM DP also indicate this change of state. After the state change, the PC re-attempts to establish a communications link to the current CPU for SIMATIC TDC/SIMADYN D and displays the new mode. STEP 7 option packages for D7-SYS - SIMATIC D7-SYS 2-35

98 CFC Please observe Recommended configuring (only for SIMATIC TDC/SIMADYN D): The interface assignment can change due to a state change. For instance, if you enter a restart command, in the "Stop due to user error" mode, via the initialization interface, then this has its configured function after restart and transition into the RUN mode. Configure a service utility at the initialization interface, to be able to test and load using the CFC via the initialization interface, also in the RUN mode Checking that the configured data and the CPU program match After loading the configured software the last time, changes could have been made, either in the CPU or FM DP or in the CFC Editor (offline). Thus, before you start testing (debugging) or commissioning the system, you should check that the configured software and program in the target system match. Prerequisites This check can be executed under the following conditions: There is a communications link between the CPU or FM DP and your PC Procedure NOTE Select the menu item PLC > Compare... The "Compare" dialog box opens. The CPU number, CPU name and the date of the last compilation are specified and compared with one another. The configured software and program in the target system are only consistent if the appropriate parameters are the same. In addition, a check is made as to whether online changes were made using another start-up tool, bypassing the CFC, or if offline changes were made, in the configured software. If the configured software and program in the target system are inconsistent, you can only activate a restricted level of test operation, where it is only possible to view and change parameter values Changing the refresh rate for monitoring The CFC Editor periodically interrogates the SIMADYN D CPU for the latest I/O value so that the values can be dynamically updated. The user can set this scan time. If values are not refreshed within 300 % of this time, for example, because the data transfer capacity of the communications link is not sufficient, or the computation performance of your PC is being fully utilized, then the values which have not been refreshed, are flagged as being faulted (refer to Section 2.3.6). In this case, you should either reduce the number of registered values or increase the refresh period STEP 7 option packages for D7-SYS - SIMATIC D7-SYS

99 CFC Procedure If you wish to change the refresh rate for monitored values, then proceed as follows: Select the menu item Debug > Test Settings...; the associated dialog box is displayed with a field for the refresh period, which can be edited. Enter new refresh periods in tenths of a second or select a new value using the arrow keys. Press the "OK" button; the refresh period then becomes valid for all values of the current CPU Activating and de-activating the test mode Before you can view (monitor) values in a CPU or FM DP, or make online changes, you must select the CFC test mode. The test functions can only be activated after first changing into this mode. In the test mode, only changes can be made in the configured software, which can be implemented and realized online. This is the only way to ensure that the assignment of objects in the configured software match that of the objects of the program in the target system. Further you can also make changes which only refer to the screen display and do not influence the program, e. g. shifting blocks. These basic functions can be activated both in the test- as well as in the create mode. The test mode refers to the CPU or FM DP, which is associated with the currently active chart. The test mode must be individually enabled or disabled for every CPU or FM DP being processed in the CFC Editor. Changing between the test- and setting mode Changes in the test mode When changing into the test- or into the create mode, the CFC still views the current chart. When changing into the test mode, it is checked as to whether the current status of the configured software matches the change release of the program. If this is not the case, for example, because you changed the configured software in the CFC create mode since the last load of the program, then the appropriate message is displayed. You can now activate restricted test operation (debugging) (only "monitoring") where you can only view and change parameter values. All of the changes made in the CFC test mode, are immediately and permanently changed in the change memory (presently, EEPROM) of the SIMATIC TDC/SIMADYN D CPU or the FM DP; i. e. when the CPU or the FM DP is reset, these changes are kept. If the CFC system crashes in the test mode, then in order to achieve a consistent status, the program must be re-compiled and loaded. The changes which you made up until the system crashed, still remain effective. If the change memory is full or defective, structural changes (blocks deleted, connections changed) are locally made in the RAM of the CPU or the FM DP; however, they are not saved. This results in STEP 7 option packages for D7-SYS - SIMATIC D7-SYS 2-37

100 CFC inconsistencies with the configured software in the CFC. (For example, in the CPU or the FM DP, the connection is changed, but not in the CFC. Remedy for a full change memory: Re-compile the configured software in the CFC and load the memory card. Remedy for a defective change memory: Replace the memory card or reset the subrack. Test-operating modes There are two test operating modes: Process mode In the process mode, the communications of the online update for the blocks is limited in order to only slightly additionally load the PC and bus. When switching-in the test mode, all of the blocks have the "monitoring off" status. In this test mode, you must select the associated block I/O and explicitly register them for monitoring. Laboratory operation The laboratory mode is selected to be able to efficiently test and commission the system in a user-friendly fashion. In the laboratory mode, contrary to the process mode, communications of the online update for the CFC charts is not limited. When switching-in the test mode, all of the blocks have the "monitoring on" status. The test mode can be selected in the create mode using the menu commands in the "Test" menu. Changeover is not possible in the test mode. Activating the test mode The test mode is activated. A check mark is displayed next to the menu item. Depending on the selected test mode, the text "test: RUN (laboratory)" or "Test: RUN (process mode)", with green background is displayed in the status bar. All of the menu functions, which are not permitted in the test mode, are de-activated (light grey font). NOTE If you made changes offline, or online using another start-up tool, bypassing the CFC, the "Different software release" dialog box is displayed. In spite of the fact that it is a different software release, this still allows you to changeover into the test mode.! CAUTION If you go into the monitoring mode, in spite of the different software releases, CFC can occasionally indicate erroneous situations, as the displayed parameter values, blocks and interconnections may not match with those in the target system. De-activating the test mode This is how you de-activate the test mode: 2-38 STEP 7 option packages for D7-SYS - SIMATIC D7-SYS

101 CFC Module status Select the menu item Debug > Test Mode The test mode is de-activated; the check mark next to the menu item and the text in the status bar disappear. This is how you activate the test mode: Select the menu item Test > Test Mode During operation, and especially during start-up, the CPU or the FM DP can identify an error condition of the configured system, e. g. if the task cannot be calculated in one sampling time, because higher-priority tasks fully utilize the available time. These statuses, which are also generally identified by the appropriate 7-segment display value of the CPU or using an appropriate LED display for the FM DP, can be analyzed using the "Module status" function. Further, when the CPU or the FM DP goes into the STOP operating mode due to a system error, it records the cause of the crash (the "exception") with information about the internal state. This information is available after restart. Prerequisites The prerequisites to determine the module state is that you have first done the following: There is a communications link between the CPU or the FM DP and your PC. The create mode is selected. You can display the error fields of a CPU or the FM DP as follows: Select the menu item PLC > Module Information... The dialog field "Module information" is opened Select the tab page "Error fields".the tab page "Error fields" is opened. The contents of the internal error field of the current CPU or FM DP are displayed as text here on the page under this tab. Displaying crash conditions They indicate the exceptions as follows: Select the menu item PLC > Module Information... The "Module information" dialog box is opened (module status). Select the "Exception buffer" tab. The page under the "Exception buffer" tab opens. STEP 7 option packages for D7-SYS - SIMATIC D7-SYS 2-39

102 CFC Monitoring block I/O The contents of the internal exception buffer of the current CPU or FM DP are displayed as text on the page under this tab. Connections (I/O) which have been registered for test, are supplied, in the test mode with the actual values from the CPU or FM DP if "monitoring" is enabled for these I/O. Prerequisites The "Monitor block I/O" function can only be executed under the following conditions: There is a communications link between the CPU or FM DP and your PC. The page view of the chart is activated. The test mode (laboratory or process mode) is selected. Monitoring in the "Laboratory mode" When the test mode is switched-in, for CFC charts in the Laboratory mode, the "monitoring on" function is also activated. This means, that in the test mode, you can display how the values of those block I/O develop, which were registered for display. This means that the values are cyclically read-out of the CPU or FM DP and are displayed. You can change the options for this dynamic value display and the parameters of the I/O in the test mode. Monitoring in the "Process mode" In the "Process mode", the "Monitoring off" function is activated. This means, that to dynamically update, you must first select the blocks (select them in the chart) which you wish to monitor; then select "monitoring on". Vice versa, for an overload condition, you can exclude individual blocks from the monitoring function (select the block and select the menu command "monitoring off"). Caution: If monitoring is switched-out and you select a connection and register this for test via, then monitoring is switched-in for this connection and for all previously registered connections of this block. When the test mode is switched-in, the connections to the CPU or FM DP are established for all listed connections of a value display window. You can activate Monitoring by marking the individual connections in the Monitoring column. Registering/deregistering connections for test In the create mode or in the test mode (process or laboratory operation), you can register individual block or chart connections for test, by selecting the connection and selecting the menu command Test > 2-40 STEP 7 option packages for D7-SYS - SIMATIC D7-SYS

103 CFC Register connections or you can click on the icon bar. in the function In the test mode, monitoring is simultaneously switched-in, i.e. the connection has a yellow background and is displayed with its actual value. If monitoring was switched-out for this block, then all of the connections, which were previously registered for test, are also switchedin for monitoring. You can de-register the connections by selecting the connection and selecting the menu command Test > De-register connections or you can click on the icon in the function bar. NOTE Alternatively: In the create mode, you can register and de-register all of the block connections for test if you call the "object properties" for a selected block and in the "connections" tab in the "For test" column, set or reset the marking of the individual connections. Connections, switchingin/switching-out monitoring You switch-in monitoring (to display the actual value of the connection) for the block connections, registered for test, as follows: Automatically when the test mode is switched-in in the laboratory mode. With the menu command Test > Monitor on or using the icon in the function bar. In the laboratory mode, this function applies for all blocks; in the process mode, only for the blocks previously selected in the chart. By selecting the menu command Test > Monitoring off or using the icon, you can disable the monitoring function, i.e. the connection values are not longer updated. In the laboratory mode, this applies for all blocks; in the process mode, only for the blocks selected in the chart. All of the input and output values, switched-in for monitoring are updated according to the set monitoring cycle. STEP 7 option packages for D7-SYS - SIMATIC D7-SYS 2-41

104 CFC Representation of the dynamic value display The values are output next to the connections corresponding to their data type. They are shown on the screen with colored background (refer to Table 2-1). Blue on white Black on yellow, stars Values displayed in the create mode (offline) Values displayed during the changeover to dynamic value display Black on yellow, value Values read-out of the CPU/FM DP displayed in the test mode #### on a red background Values, requested from the CPU/FM DP and which are not available, are displayed (error condition) Table 2-1 Displaying values in the CFC Editor (pre-setting) Parameterizing block I/O An important task at start-up (commissioning) of a control system is optimizing the control parameters, i. e. setting the correct parameter values at the block inputs. With this function, you can change the values at the inputs of the blocks during operation and simultaneously monitor the effects in the control process.! CAUTION Please observe that death, severe bodily injury or significant material damage can occur if changes such as these are made with the system connected to the process and without having taken the appropriate precautionary measures. Prerequisites The "Parameterize block I/O" function can be made under the following conditions: There is a communications link between the CPU/FM DP and your PC. The page view of the chart is activated. The test mode is selected. Procedure In order to change an input (not connected) then proceed as follows: Double-click on the input which is not connected, and whose value you wish to change. The dialog box "I/O properties" is displayed. Enter the required parameter value in the "Value" input field. By pressing the "OK" button, the value is transferred into the working memory of the CPU/FM DP and into the configured software. The dialog box is then closed STEP 7 option packages for D7-SYS - SIMATIC D7-SYS

105 CFC NOTE The default for the output value cannot be changed online. This is also true for function blocks which have been newly inserted Creating and deleting interconnections For SIMATIC TDC/SIMADYN D/FM458-1 DP, you can make changes to the control structure during operation; this also includes "Creating and deleting interconnections".! CAUTION Please observe that death, severe bodily injury or significant material damage can occur if changes such as these are made with the system connected to the process and without having taken the appropriate precautionary measures. Prerequisites The "Creating and deleting interconnections" function can be executed under the following conditions: There is a communications link between the CPU/FM DP and your PC. The page view of the chart is activated. The test mode is selected. The configured software and CPU/FM DP are consistent. Creating interconnections To interconnect an input, which was previously not connected, to an output, proceed as follows: In the chart, using the left mouse key, mark the output which you wish to interconnect to the input; the color of this output changes. Position the mouse pointer in the chart to the input which up until now has not been interconnected and which you now wish to connect. Depress the left mouse key. The interconnection is now displayed as a line in the chart. At the same time, a data connection is established between the I/O in the working memory of the CPU/FM DP. Deleting interconnections To remove an interconnection between an input and an output, proceed as follows: Select the block input in the chart, which you wish to remove and then delete the interconnection with Edit > Delete. The connecting line between the connections disappears, and the last value, which was transferred at the data connection, is displayed as parameter value at the input. NOTE: Interconnections to global operands can neither be created online nor deleted online. STEP 7 option packages for D7-SYS - SIMATIC D7-SYS 2-43

106 CFC Inserting and deleting blocks For SIMATIC TDC/SIMADYN D/FM DP, you can make changes to the control structure during operation; this also involves "Inserting and deleting blocks".! CAUTION Please observe that death, severe bodily injury or significant material damage can occur if changes such as these are made with the system connected to the process and without having taken the appropriate precautionary measures. Prerequisites This function can be made under the following conditions: There is a communications link between the CPU/FM DP and your PC. The test mode is selected. The block catalog is open (menu item View > Catalog) Inserting blocks To insert blocks online, proceed as follows: In the block catalog, select the required block type, and with the left mouse key, drag it to the required position at a free location in the chart. The block is simultaneously inserted in the software as well as in the working memory of the CPU/FM DP at the standard insertion position of the run sequence. Note Some block types cannot be inserted online. If these block types are selected, an error message is output. Deleting blocks In order to delete blocks online, proceed as follows: Remove all connections from the outputs of the block to the inputs of the other blocks. Proceed as described in Section Connections to global operands do not have to be deleted. Position the mouse pointer in the chart at the block to be deleted and press the right mouse key. A pop-up menu is displayed. In this pop-up menu, select the item "Delete", the block is deleted from the chart and is no longer processed in the working memory of the CPU/FM DP STEP 7 option packages for D7-SYS - SIMATIC D7-SYS

107 CFC Changing the I/O number of generic blocks Proceed as follows to change the number of I/O of a generic block online: Position the mouse pointer in the chart at the associated block and depress the righthand mouse key. A pop-up menu is displayed. In this pop-up menu, select No. I/O...; a dialog box is displayed in which you can select the required number of block I/O. NOTE It is not permissible that a connection has been registered for monitoring. Generic blocks are, e.g. adders and multiplexers Communication interfaces For SIMATIC TDC/SIMADYN D, you can structure the communication links between the PC and CPU in several ways. The local service interface of the CPU (front panel connector) is provided by the system (and is therefore always available). This serial interface permits communications with the CPU itself in the operating mode STOP after fatal system errors ("H" on the CPU display). For a single-processor system (e. g. T400) this is the only interface for test and start-up. If this interface is to be used to load and test (debug) multi-processor systems, then the connecting cable must always be inserted at the actual CPU. Thus, to test multi-processor systems, we recommend a configured service interface. This allows the service connection for a complete station to be made available at one or several communication interfaces. System-wide bus operation for test and start- up (commissioning) is possible if an SS52 MPI module is used as interface module for this connection instead of the serial SS4 module. Even when first commissioning a station, you are not limited to just a local interface. Communications via the so-called initialization interface is possible as soon as there is a certain level of harmonization between the CPUs of a station (this can be identified by a "0" on the CPU display) (only for SIMADYN D). For example, the CPU programs for a complete station can be loaded online via this interface, without having to changeover cables. For the FM DP application module, the communications link between the PG/PC and the module is always established via the interface of a SIMATIC CPU or a SIMATIC CP in the same rack (as is usual for SIMATIC). Local service interface When using the local service interface, this must be connected with a free serial interface of the PC (COM1 or COM2). STEP 7 option packages for D7-SYS - SIMATIC D7-SYS 2-45

108 CFC Configured service interface How a configured service interface is handled, depends on whether a serial SS4 module or an SS52 MPI module is used for the interface. If an SS4 interface is used, this should be connected with a free serial interface of the PC (COM1 or COM2). The connecting cable uniquely defines the station to be addressed and the SS4 interface to be used. When an SS52 or CP50M0 MPI interface is used, the station cannot be uniquely defined, as several SS52 MPI connections of a single station can be connected to the same bus. The configured software can tell you which MPI connections have been configured for the station, but the PC does not know which of these connections it should use. In this case, the PC checks all of the configured connections one after the other, until it can establish a communications link to the "Service" utility of the CPU. The PC can then use this connection for communications. NOTE In order to access a CPU via the configured service interface, you must include an appropriate service utility function block in your configured software. If you require more information, refer to the Chapter "Service utility" in the User Documentation "System- and communication configuring D7- SYS". Initialization interface Creating connections Selecting the communications interface Setting the MPI interface The initialization interface is always the top connection of the CS7 module which is inserted at the far left in the subrack. To be used as initialization interface, either an SS4 module or SS52 module must be inserted here. This connection can only be used as initialization interface, as long as the CPUs of the station are in the operating mode "STOP due to an initialization error". The connection between the CFC and the "Service" utility of a CPU/FM DP is essentially automatically established. You must only insert the serial connecting cable at the correct SS4 module and at a free serial interface on the PC (COM1 or COM2) or the MPI bus cable at the appropriate SS52/ CP50M0 module or the appropriate SIMATIC CPU for FM DP and at the PC MPI port. You tell the CFC which communications interface is to be used. To do this, start the program via the Windows 95/NT task bar Start > Simatic > STEP 7 > Set PG/PC interface and select the right alternative. This selection is kept even after you power-down your PC. You must set the correct operating parameters of the MPI interface at your PC if you wish to establish an online connection via the MPI interface. Refer to the help info for the dialog box to obtain information as to how you should proceed STEP 7 option packages for D7-SYS - SIMATIC D7-SYS

109 CFC The baud rate for the MPI interface must coincide with the coupling partner. NOTE The maximum baud rate for the particular protocol may not be exceeded. Checks when establishing a connection When establishing a connection in the test mode and changing the CPU mode, the CFC checks whether it is connected with the correct CPU/FM DP; if this is not the case, the connection is canceled and an appropriate message is output. When establishing the connection for online loading, the CFC checks whether it is connected with the correct CPU/FM DP; if this is not the case, you are prompted as to whether you still wish to load. In all other cases no check is made. STEP 7 option packages for D7-SYS - SIMATIC D7-SYS 2-47

110 CFC 2.4 Creating block types If you have installed the "D7 SYS" software package, you automatically have access to the block types in the standard "FBSLIB" block library. You can use these to configure your system in the CFC. You can import additional standard block libraries (FBSLDC, FBSLT1, FBSWCC and FBSLSL). Further, you can create the block types yourself, by creating a user library from charts Creating a user library from charts If you always re-use certain functions when configuring your system in the CFC, you can create block types from charts. A user library is created when compiling the charts. The block types in this library can be used when configuring your system, just like the existing function blocks from the standard block libraries. NOTES All charts of a chart folder are compiled and combined in a user library. The interface of a chart, which is to be compiled, is the future interface of the appropriate block type. The interface comprises the margins at the lefthand and righthand side of a CFC chart. They contain, on one hand, the references to the interconnected objects e.g. other blocks or task groups, which are not on the actual sheet. On the other hand, they contain the number of the connection (transition point) if the autorouter cannot draw the connecting line to the margin because the sheet is too full. Init values at blocks within a chart, which becomes a chart block, are not taken into account; this means that a block with Init values at the outputs behaves differently as a single block (Init value) than within a chart block (no Init value). The libraries created are saved in the "s7cfc\sdblocks" directory of the STEP 7 installation. If you wish to work with a symbolic representation of the created block types, then you can locate the bitmaps which you created ("block type name.bmp" type) in the "s7cfc\sdblocks\icons" directory STEP 7 option packages for D7-SYS - SIMATIC D7-SYS

111 CFC Name syntax The names of all chart interfaces must be unique: 1 to 3 alphanumeric characters, only upper case letters, the 1 st character must be a letter. The name of the created block type must be unique: 1 to 6 alphanumeric characters, only upper case letters, the 1 st character can be a letter or a "@", a "_" is also permitted for the 2 nd to 6 th characters. The library name must be unique: 1 to 6 alphanumeric characters, only upper case letters, the first character must be a letter; a "_" is also permitted for the 2 nd to 6 th characters. Restrictions The CFC chart is subject to specific rules, if it is to be compiled in a block type for SIMATIC TDC/SIMADYN D or FM DP: Only top charts can be compiled in block types. The chart may not include any other charts (chart nesting is not permissible). Block types, created with CFC are permitted. Interconnections between charts are not permitted. No pseudo comments may be configured at the interface I/O of the chart and the blocks contained in them. All of the blocks must be located in the same task. In this task, the blocks of the chart must follow one another directly. The chart folder to be compiled may never contain any run-time groups. If the chart includes blocks, which has attributes, then the block type, created with CFC also takes on these attributes. Global operands must be routed through to the chart interface. For SIMATIC TDC/SIMADYN D or FM DP, a block type may have a maximum of one symbolic hardware address (global operand). Prerequisites Before you create a user library from the chart, you must have completed the following preparatory steps: 1. You must have created a chart folder in SIMATIC Manager. The system library "FBSLIB" is automatically imported into this chart folder. 2. You have configured the charts in CFC. 3. In CFC, you parameterized, for each chart, which is to be compiled, a chart interface. 4. In CFC, you opened a chart of the chart folder to be compiled STEP 7 option packages for D7-SYS - SIMATIC D7-SYS 2-49

112 CFC Procedure NOTE In order to create a user library from charts, proceed as follows: 1. Make a consistency check, in order to check that the charts can be compiled as block types: Select the menu command Chart > Consistency Check > Chart as Block. The "Check the charts as block types" dialog box is displayed. If you press key F1 with the dialog box opened, you will receive additional help. 2. Compile the charts as block types: Select the menu command Charts > Compile > Chart as Block. NOTE The "Create a library from charts" dialog box is displayed. If you press key F1 with the dialog box open, you obtain additional help. 3. Import the created library in order to use the created block types to configure your system. 2.5 Chart reference data-documentation Chart reference data This Chapter describes how you can create the chart reference data for comprehensive documentation of your CFC configuring structure. In addition to graphic CFC displays, you can display and print the following information in list form using the "Chart reference data" function: Cross references Listing the accesses to different objects. Run sequence The complete run sequence of a CPU. You can check the structure of your configured software in this fashion. Cross-reference lists You can display and print the following chart reference data lists: Cross references, operands The list shows all of the global operands, used in the project together with the elements which they access. Cross references run-time groups The list shows which run-time groups are accessed from any CFC charts. Cross references block types The list shows the block types used and the positions (CFC chart) where they are used STEP 7 option packages for D7-SYS - SIMATIC D7-SYS
