9 SFC Visualization (SFV) 3 Introduction You can use the "SFC Visualization" software package to configure SFC visualization in WinCC and to perform operator control and monitoring of SFCs and SFC instances in the WinCC runtime system. What is SFC? SFC (Sequential Function Chart) is a sequential control system that is used for control floworiented process control. A sequential control system is a controller with automatic, step-wise execution. It switches from one state to the next depending on conditions. Note In this manual, we generally refer to the SFCs and SFC instances as SFCs, unless these objects need to be distinguished in the respective context. What does the SFC Engineering System offer? The engineering system allows you to create SFCs, SFC types and SFC instances, compile and download them to the CPU, and test and commission them. In order to be able to use the SFCs in the runtime system, you must transfer them to the runtime system from the engineering system using the "AS-OS-Engineering" software package. You can also transfer charts individually. You transfer the SFCs with their OS comments and configured messages. Mechanisms are stored with the messages that enable you to directly access the SFC that the message pertains to. You can also perform the following actions: Configure the display of SFCs Configure global operator authorizations for the SFCs and specific operator authorizations for each SFC Place objects in the WinCC display for calling the SFCs You will find more information in the SFC Sequential Function Chart Manual in the SIMATIC STEP 7 User Manual and in the corresponding online help. What does the Runtime system for SFC offer? The runtime system enables simultaneous operator control and monitoring of any number of SFCs. Programming and Operating Manual, 06/2018, A5E AC 9

10 SFC Visualization (SFV) Note Configuration is not possible during runtime operation. You can transfer SFCs to the runtime system even while the OS is running. This may cause a temporary inconsistency in the displays, since the SFCs must first be downloaded to the automation system before being loaded on the OS. The potential for inconsistencies during this period is unavoidable. 10 Programming and Operating Manual, 06/2018, A5E AC

11 Basic SFC settings 4 Settings in WinCC Explorer The general settings for the visualization of SFCs and SFC instances within the runtime system are made in WinCC Explorer. You can make these changes globally for all displayed SFCs or for specific objects. Global Settings Global settings for displaying SFCs affect the following areas: Topology Colors Authorization level Group display To open the "SFC" dialog, select "SFC" in the WinCC Explorer and open the shortcut menu. Then, select the menu command Open. You can specify the size of the objects and the distance between them for the topology in the detail area and overview area. Use the check box "Always show in faceplate" to specify if the SFC faceplate is always displayed. You choose colors to distinguish the states of steps, transitions and selected objects in the display. You change the authorization levels for operator inputs if you require levels other than the default levels ("Monitoring", "Process Operation" and "Advanced Process Operation"). These settings apply to all SFCs in the relevant WinCC project, unless specific authorization levels have been set for the SFC in question. These authorizations remain in place following OS compilation. In order to grant a user the authorization to perform operator inputs in SFC Visualization, the corresponding authorization levels must be enabled for this user (globally or area-specific) in the User Administrator. If no users are configured, all operator inputs are permitted without restriction. In this case, the "Authorization Levels" tab is not available. To access the configuration for the group display, choose the "Group Display Properties" button on the "Group Display" tab. In the Group Display window, the following additional tabs are available: Tab Geometry Colors Style Setting Size of the display fields Background color of the display fields 3D frame width (in pixels) Programming and Operating Manual, 06/2018, A5E AC 11

12 Basic SFC settings Tab Font Flashing Other Message types Lock Assignment Setting Font attributes (font, alignment etc.) Flashing frequency Other attributes, such as enabled for operator, group relevant, display, group value and acknowledgment pattern Display text and attributes (font color, background color, flashing) for the individual message statuses Whether the messages are output or locked. An "x" (default setting) appears in the display field to indicate that messages are locked. You can change the default setting. Message type for each display field Note Global settings when using the "User-configurable message classes" function When the "User-configurable message classes" function is used in the PCS 7 message system, the settings named above are defined for the group display of configurations for this function and cannot be changed in WinCC. Object-Based Settings (on server only) You can make the following settings individually for each SFC: Configuring the update cycle Configuring the standard view. This is the overview window or detail window with which the SFC is opened. Configuring the operator authorization levels The available SFCs are displayed in the detail window of WinCC Explorer when "SFC" is selected. To edit object-based settings, open the shortcut menu of the selected SFC and select the menu command Properties. 12 Programming and Operating Manual, 06/2018, A5E AC

13 Configuration Configurations for SFC Visualization Introduction You can place objects in a WinCC display that enable you to open an SFC during runtime operation. The following objects can be used for this: Block icons "PCS 7 SFC Control" "PCS 7 SFC MultiChart Control" "PCS 7 SFC Topology Control" Any graphic object (such as a rectangle) A Windows object (such as a button) Preparation Select the menu command Options > 'Compile Multiple OSs' Wizard' > Start... in SIMATIC Manager in order to transfer the SFCs and SFC instances to the OS. Then, carry out the Preparations for the Controls. You can find additional information on this in the section: Preparing the controls (Page 19) Note The controls "@PCS 7 SFC Panel Control" and "@PCS 7 SFC SP Control" supplied with SFC Visualization are controls required internally in SFC Visualization. They have not yet been approved for use in WinCC pictures. You can configure the following objects for opening the SFC: Configuring SFC block icons (Page 15) Configuring SFC faceplates (Page 17) Configuring status picture "PCS 7 SFC Control" (Page 20) Configuring status picture "PCS 7 SFC MultiChart Control" (Page 22) Configuring status picture "PCS 7 SFC Topology Control" (Page 24) Configuring the SFC button (Page 25) Configuring the SFC browser selection (Page 26) You can use SFC Visualization functions in order to create your own scripts.

14 Configuration 5.1 Configurations for SFC Visualization You can find additional information in the section "Using functions for user-specific scripts (SFC API Calls) (Page 27)". 14 Programming and Operating Manual, 06/2018, A5E AC

15 Configuration 5.2 Configuring SFC block icons 5.2 Configuring SFC block icons SFC block icon templates The block icon templates for the SFC and the instance of an SFC type are provided in the template picture. The templates for the block icons can be present in different versions. The variants of a block icon are distinguished by the "/" character at the end of the icon name, e.g. "<icon name>/2". Variants "1" and "2" are already present as standard. Other variants are possible. Variant Remark 1 Standard PCS 7 style 2 APL-based style 3 and higher User-defined variants <Variant name> User-defined variant; freely selected variant name; max. 16 characters Example: Block icon for an instance of an SFC type "@SFC_TYPE/2" in variant "2". Procedure for creating variants Use the following procedure to perform all changes, for example, to create several variants of a type: 1. Copy this picture and save it with a new name in the project directory. Change, for example, the previous file name "@PCS7TypicalsBasisLibraryV8.pdl" to "@PCS7TypicalsBasisLibraryV8_1.pdl". If there are several copies of this file, the one used to create OS pictures is always the one with the alphabetically sorted ending. For example, the files with the ending "..._1.pdl" to "..._3.pdl". In this case, the file with the ending "..._3.pdl" is used. 2. Create an additional block icon in this copy for each SFC type using the copy/paste commands. You assign a variant number or a variant name for the new block icon: Variant name: This name must be entered in full for configurations. Variant number: Please observe the tag table mentioned above. For configurations, only the variant number needs to be entered. 3. Then open the properties for each block icon. 4. Under "General", replace the value (@SFC_TYPE, for example) for the attributes "StructureType" and "type" with the name of the corresponding SFC type. Programming and Operating Manual, 06/2018, A5E AC 15

16 Configuration 5.2 Configuring SFC block icons Create block icons You can create block icons for your OS picture in two different ways: Automatic creation in the plant hierarchy With this method, the required block icons are automatically inserted into the picture and parameters are assigned, as appropriate, for all existing SFCs. You can find additional information about this in the online help of the PH in the section "How to automatically create/update block icons for OS pictures". You place the OS picture in WinCC in the Graphics Designer and configure it with the Dynamic Wizard. You can find this description below. Procedure in WinCC 1. Copy the required block icon from the template to your current picture. 2. Adapt the "StructureType" and "type" property to the type name (not necessary for the block icon for SFC). 3. Select the block icon and double-click "Connect faceplate to process tag" in the "Standard Dynamics" tab of the "Dynamic Wizard" window. The Dynamic Wizard opens. 4. Click on the"..." button on the "Set options" page. The "Tags - Project:" dialog box opens. 5. In the WinCC tags, open the "List of all tags" and double-click the corresponding tag for the chart or instance in the right window to select it. The dialog box closes; the tag name is entered in the Dynamic Wizard. 6. Click "Next". The next page shows what the wizard is now generating. 7. Click "Finish". The block icon is now configured. You can use it to call the associated faceplate in runtime operation. 16 Programming and Operating Manual, 06/2018, A5E AC

17 Configuration 5.3 Configuring SFC faceplates 5.3 Configuring SFC faceplates SFC faceplates There are two types of faceplate templates for visualizing the various SFC instances of the SFC types and for visualizing SFCs in runtime: The variant is used to visualize SFCs. The variant is used to visualize SFC instances of an SFC type. The interface elements (setpoints, control strategies, for example) that are configured in the "Characteristics" dialog box are included in this faceplate. In addition to the display objects (type name/instance name, comment, group display, etc.) that are created with the standard WinCC resources, the faceplates contain an OCX for displaying and manipulating the operating state logic and an OCX (for SFC instance) for displaying and manipulating the setpoints. You also use these OCX in SFC Visualization. The meaning of the elements contained in the faceplate in all views is described in: Operating and monitoring the SFC by means of faceplate (Page 32) Configuration The faceplates are supplied preconfigured and you can customize them individually. You can also create your own faceplates from the templates. However, you use the available OCX for displaying and manipulating the operating state logic and the setpoints (for SFC instance). You can find a detailed description of the configuration of faceplates in the manual PCS 7 Programming Instructions for Blocks. Additional information You can find additional information in the section: Adapting SFC faceplates (Page 18) Programming and Operating Manual, 06/2018, A5E AC 17

27 Configuration 5.11 Using functions for user-specific scripts (SFC API Calls) 5.11 Using functions for user-specific scripts (SFC API Calls) SFC API functions The Graphics Designer contains template scripts for assigning certain actions to objects. SFC Visualization offers many functions. The most important functions are included in these script templates. You can also use the functionality of SFC Visualization in your own scripts. For this purpose, you read in the "sfccli.h" header file. Insert the line ' # include "sfccli.h" ' in the script. The most important functions are described in: SFC API functions (Page 97) General Information about the Functions If a Boolean value is returned, then TRUE = success and FALSE = error. Functions that have "LPOHIO_ERRORSTRUCT IpdmError" as a parameter can be called with "(void*)0". The error is not evaluated in this case. If a window handle is needed, specify the window of the "parent" for this new window. "NULL" is also allowed as the assignment. In this case, the desktop is used as the "parent" of the new window. Programming and Operating Manual, 06/2018, A5E AC 27

28 Configuration 5.12 What you should know about OS Server and OS Client 5.12 What you should know about OS Server and OS Client What is an OS Server? An OS Server is interconnected with the AS. It receives process data, however, it usually does not provide any operating and monitoring functionality within a multi-user system. The OS Server contains all of the configuration data, and you can modify these data here. What is an OS Client? An OS Client is an operator station (OS) on which you can operate and monitor the process in runtime. A client neither has its own SFCs, nor any process I/O. The Client lets you operate and monitor SFCs on the OS Servers, however, it does not allow their editing. How do I access OS Server data? Server project data are made known to the client by means of reference lists (packages). The client can access the server data only after the packages have been generated and downloaded. The same applies to SFC Visualization, where only references to the SFCs are exported instead of the actual data. You therefore do not have to recompile and download the packages again after having edited an SFC. You only have to generate and download a new package to the client only if SFCs have been deleted, added or renamed. You can find additional information in the Process Control System PCS 7; Operator Station Configuring Manual. Configuring SFC Visualization You can configure the visualization and operator controls in WinCC Explorer on the client as described in the "Basic SFC settings" section of this documentation. The basic SFC settings available for the server projects are not relevant to the client. If not configured otherwise, the default settings are activated for the client. In a multi-client project you can place objects for opening SFCs in graphic displays and interconnect these with SFCs similar to the server project. You can find additional information on this in the section: Configurations for SFC Visualization (Page 13). You must download the corresponding packages to the client for this. Note on server project configurations Configurations for SFC visualization in graphic displays (for example, SFC selection buttons, SFC status display) will also work on the client. Server projects can be configured at the client. Information about corresponding procedures is available in the Process Control System PCS 7; Operator Station Configuring Manual. 28 Programming and Operating Manual, 06/2018, A5E AC

29 Configuration 5.12 What you should know about OS Server and OS Client Permanent operability for clients SFC Visualization supports "permanent operability" for clients. A preferred server configured on the client is used as the server. This applies regardless of whether the server is the current MASTER or STANDBY. If there is a redundancy failover SFC Visualization reacts in accordance with the behavior defined in WinCC. Programming and Operating Manual, 06/2018, A5E AC 29

31 6 6.1 Access control Access control Operator input is allowed without restriction if no users are configured. The following settings or functions are performed, depending on the logged on user and the authorization levels configured for SFC Visualization: Operator input buttons are activated or deactivated. Operator input is subject to verification. This input is either accepted or discarded, depending on the result. The change of the allocation status of equipment modules. The "Allocation" operation of the "Higher process controlling" authorization level is required to perform this change. The authorization levels set on the Engineering Station are transferred to the OS server (OS > Load target system), where they are used in runtime operation. Global and SFC-specific authorization levels can be configured on an OS server. However, these are overwritten the next time the function OS > Load target system is used. If SFCspecific authorization levels exist on the OS server, these are used at runtime. If no SFCspecific authorization levels are configured, the global authorization levels of the OS server are used. On an OS multiclient, only SFC-global authorization levels can be configured. If SFCspecific authorization levels exist on the OS server, these are used at runtime. If no SFCspecific authorization levels are configured, the global authorization levels of the OS multiclient are used. An OS Web Server does not have its own authorization levels. The relevant authorization levels are transferred depending on whether it is an OS multiclient or an OS server. An OS Web Client does not have its own authorization levels. The authorization levels of the OS Web server are used at runtime. Note If button or a setpoint is not enabled although the user has the necessary operator authorization, then operation may be disabled on the block (for instance ENSTART = 0).

32 6.2 Operating and monitoring the SFC by means of faceplate 6.2 Operating and monitoring the SFC by means of faceplate Overview You operate the SFC and the SFC instance by means of a faceplate. Overview row in all views A faceplate for SFC or SFC instance provides display and operator controls in the "overview row", for example group display, status displays and buttons for selecting the view. You can find a detailed description on this in the section "Structure of the overview row of the SFC faceplate (Page 33)". Views The faceplate for the SFC has the following views: "SFC" faceplate, "SFC section" view (Page 44) "SFC Chart" faceplate, "Messages" view (Page 38) "SFC/instance" faceplate; "Overview" view (Page 46) The faceplate for the SFC instance has the following views: "SFC Instance" faceplate, "Actual Values" view (Page 39) "SFC Instance" faceplate, "Messages" view (Page 43) "SFC/instance" faceplate; "Overview" view (Page 46) "SFC Instance" faceplate, "Prepared Values" view (Page 49) "SFC Instance" faceplate, "Parameters" view (Page 48) "SFC Instance" faceplate, "Block contacts" view (Page 50) "SFC Instance" faceplate, "Batch" view (Page 51) "SFC Instance" faceplate, "controls" view (Page 52) "SFC Instance" faceplate, "is controlled by" view (Page 54) Note You can only ever start an SFC instance in the faceplate in the "Prepared Values" view. This is most important if control strategies or setpoints are being used, because a control strategy and setpoints have to be set prior to starting. Note When you open the faceplate, the "Prepared Values" view (Idle or MANUAL mode) or the "Actual Values" view (in all other operating states) is displayed depending on the current operating state of the SFC. When a faceplate is open, a change in the operating state does not automatically change the view. 32 Programming and Operating Manual, 06/2018, A5E AC

33 6.3 Structure of the overview row of the SFC faceplate 6.3 Structure of the overview row of the SFC faceplate Overview The figure below shows the layout of the elements of the overview row. Functional dependencies are not taken into consideration for the display. The faceplate for SFC or SFC instance provides the following display and operator controls: (1) Group display (2) Lock messages (3) Suppress messages (4) Acknowledge messages (5) Batch display (6) Allocation display for EM (7) Context of the SFC associated with the faceplate (8) Calling up the views of the block (9) Back to block icon (10) Pin faceplate (11) Instance name of the block Note You can learn about additional operator controls in the block-specific blocks. (1) Group display The group display shows the current status. Meaning: "A" = Alarms "W" = Warnings "S" = Malfunctions/Step error "O" = Operator prompts Programming and Operating Manual, 06/2018, A5E AC 33

34 6.3 Structure of the overview row of the SFC faceplate Information about the operator prompt "O": The icon above for operator prompt "O" is also displayed here if one of the following status displays of the sequencer exists after the CPU startup: Startup with consistent data Startup with inconsistent data You can find additional information about the status display in the section ""SFC Instance" faceplate, "Actual Values" view (Page 39)". (2) Lock/unlock messages You can use this button to lock or unlock block messages. The block's messages are displayed again in the group display when you unlock the messages. The block instance then resumes sending new messages. Messages generated in the locked phase are displayed when you enable the message function. The operator authorization level for this button is set in the internal This variable is created by the OS project editor. The logged-on user has to have the authorization for the area to which the block is assigned for the button and function to be enabled. For reasons of optimization, the operator authorization level set in variable also has to be available at an OperationLevelx of the block icon of the process tag (for example higher process operation control). Otherwise, operator control of the button "Lock messages" is not possible. You can hide this button from specific users / user groups of the plant by using the operating authorizations in the PCS 7-OS. You can find more information on this topic in the documentation Process Control System PCS 7; OS Process Control. Note Since the disabling of block messages must be confirmed via the PCS 7 system dialog as of V8.1, the operator can also enter a reason for the disabling in this dialog. The inputs are always confirmed with "OK", even in 2-step operation. (3) Suppress messages The following icon shows that message suppression is activated. 34 Programming and Operating Manual, 06/2018, A5E AC

35 6.3 Structure of the overview row of the SFC faceplate The "Suppress process messages" function is activated with the MsgLock parameter in the AS block. If message suppression is activated, all messages in this block instance except for process control messages are suppressed. (4) Acknowledge messages You can acknowledge all messages from the block instance using this button. You can hide this button from specific users / user groups by using the authorization in the PCS 7 OS. You can find more information on this topic in the documentation Process Control System PCS 7; OS Process Control. (5) Batch allocation display The icon is displayed when SIMATIC BATTCH is allocated to the block instance of the SFC of an EPH/EOP. (6) Allocation display for Equipment Module (EM) This displays whether an equipment phase (EPH) is allocated to the associated SFC of an equipment module (EM). "Equipment module (EM) is allocated by an equipment phase (EPH)" Displayed at the faceplate of the equipment module. "Allocation at an equipment module (EM) has failed" Is displayed at the block icon of an equipment phase (EPH).
