They consist of max. 299 storage locations called pages. The structure of a page is comparable to a field in a "container", where each container can hold up to 110 data elements with different types (BOOL, INT, BYTE, REAL, etc.). In the simplest case, a page consists of a single container. Each container of a page can be addressed by one control variable (two in the case of twodimensional fields). As opposed to NC parameters, machine data can be modified during the run time. Both the user interface and the PLC or an NC program can have read access and, if the corresponding authorization is available, write access to the data elements of a container. Machine data are divided into two subsets: system machine data (pages 1 to 99) and user machine data (pages 100 to 299). A basic requirement made of a control is the capability to parameterize operations and intermediately store process data. The MTC200 provides the user with the machine data for this. The basic elements of the machine data are constituted by the data elements, which can be read and/or written by the user, by the PLC and by the NC program, even during run time. The data elements, derived from various elementary data types, can be collated in max. two dimensional fields of identical structures (pages). The MTC200 distinguishes between two groups of machine data pages:

6 1-2 Introduction Machine Data Handling Machine Data Management System pages User pages System pages are used for: dynamically variable "NC parameters" and for the display of status information in variables for specific control functions such as setup registers, drag and Gantry axes or main spindle synchronization. Pages 1 to 99 are reserved for this. Although machine data elements within these pages can be read and, if permitted, written, the page structure cannot be modified. Machine data pages 100 to 299 are reserved for the user. Data such as machine options, measuring data or data from OEM-specific functions such as workpiece pallet management, as well as geometry data, tolerances for parts manufacturing, axis positions or data used in userspecific programs can be managed here. Utilization is solely dependent on the requirements and the "creativity" of the user. The creator of the page himself determines whether and to what extent access to user data is permitted. The conditions under which access is permitted can be indicated when declaring a variable. 1.3 Definitions Machine data block Machine data page A machine data block always consists of a number of machine data pages. Within the Configuration view, one machine data block can be created and edited for each NC parameter block. All system pages are always contained in each machine data block. The individual machine data blocks can, however, include entirely different user pages. "Machine data block" is the generic term for a maximum of 299 memory areas ("pages"), the structures of which are not determined in the system software (e.g. as with the NC parameters), but in case of need can be created (declared) and adapted themselves. The design of a machine data page is comparable with a field of identical structures (containers). In the simplest case, a page consists of a single dimension field of structures which contains at least one single structure. For more complex requirements, it is also possible to declare two dimensional fields of structures in a page. Note: The maximum size of a machine data page is limited to 64 kb. The control variables of both dimensions must be within the range of to

In the following operation, the control and the user interface then refer to the appertaining data (e.g. processes and axes) in the NC parameters. If, by way of example, the control variable type PROCESS was selected for control variable 1, the control considers only the processes indicated in the current NC parameter block and the process designations defined in the NC parameters are displayed by the user interface in the selection of control variable 1 (of a process). The following types are available as control variable types: IP_AXIS: axes of the type Feed axis SP_AXIS: axes of the type Spindle PROCESS: processes AXIS_DES: axes of the type Feed axis and of the type Spindle NO_CLASS: user-definable type within a range of to Machine data elements which belong together functionally are collated in structures (containers). Every structure (container) can contain up to 110 machine data elements (variables) of different data types (e.g. BOOL, INT, BYTE, etc.). Every machine data element of a structure is characterized by its serial number, its designation, its elementary data type and its access authorizations Fields are inadmissible as an element of a structure. The available elementary data types are summarized in a table at the end of the chapter.

8 1-4 Introduction Machine Data Handling Machine Data Management 1.4 Data Handling Memory Locations for Machine Data Generally, machine data can be saved in 2 "locations": in the PC and in the control. A machine data block for a machine is always first created in the PC, adapted accordingly and stored. This has the advantage that the planning and scheduling operations can generate or alter machine data blocks without necessarily having to be connected to the target machine. The machine data block is then loaded into the target control and is active. Active machine data block. If structural modifications are then carried out on this machine data block (deleting/adding/modifying user pages), the identification switches from "active" to "last loaded into the control". This status is represented as follows: Machine data block last loaded into control (and meanwhile modified structurally). Accordingly, a machine data block loaded from the control (Upload function) is at first "active". Due to structural modifications, this then becomes the "machine data block last loaded from control" and is indicated accordingly by the following bitmap: Machine data block last loaded from control (and meanwhile modified structurally). Whereas a number of machine data blocks (e.g. for different machines) can be stored in the PC (hard disk), there is only one single machine data block in the control itself. This machine data block determines the performance of the CNC. The machine data block that is currently located in the control (Index 00) is thus indicated as the "Current machine data block" and is indicated by the following bitmap as: Current machine data block. Summary: PC: Active machine data block. Machine data block last loaded into the control. Machine data block last loaded from the control. Control: Current machine data block.

9 Machine Data Management Introduction Machine Data Handling 1-5 Editing Machine Data an Overview Defining machine data blocks Data exchange between interface and control The user interface of the MTC200 provides the following main functions for the management and editing of machine data: management of entire machine data blocks: new, copy, cut, paste, export, import and delete, management of pages: new, copy, cut, paste, rename and delete; ASCII export and import, configuration of individual pages: define and alter the structure; define and alter data elements, parameterize all the variables of a page: display and alter data elements. In the scope of communication between PC and control, it is possible to use the user interface to: transfer a complete machine data block, or only the data of a single page of a machine data block, from the PC to the control, transfer a complete machine data block from the control to the PC, or directly access the machine data block of the control online from the PC. In this case, the display or alteration of variable values in the individual pages is possible. Page structures of the machine data block in the control (current machine data block) cannot be altered online, though.

It is thus also possible to alter the values of the machine data elements (variable values) during the running time (online), unlike the NC parameters. A detailed description can be found in Chapter 6. Different Machine Data Blocks in PC and Control The PC can access a machine data block in the control only if and when it has stored an identical copy of the machine data block (current machine data block, component of NC parameter block 0). It needs this copy to recognize units, limit values and other data from the individual pages. By this means, access is possible only to data which is in the definition range of the NC parameters. If it exists, the current machine data block is always identical to the machine data block located in the control.

13 Machine Data Management Operational Concept Operational Concept 2.1 Guidelines Every node point has its own menu entries in the menu bar, its own F key assignments and pop-up menus. The pop-up menu is opened using the right mouse button or with the shortcut <SHIFT>+<F10>. The default function in this pop-up is represented with a status (*) in front of the function and is executed when the node is selected and the <RETURN> key is pressed. The shortcut control commands for Copy (<CTRL>+<C>), Paste (<CTRL>+<V>), Cut (<CTRL>+<X>) and Delete (<DEL>) are triggered by the Project Navigator. The following desktop elements are used for operation in the user interface: Menu bar with hot key support Mouse F key bar using the keyboard (cursor keys, Tab, Space and Enter keys) Fig. 2-1: Operating within the graphical user interface Bedienoberfläche_gr.bmp Menu bar Mouse F key bar The menu bar is adapted depending on the screen section selected. This results in the editing possibilities. In addition to all the possible operation controls, such as menu bar, F key bar and left mouse button, the mouse also provides an editing selection list, i.e. by opening a pop-up menu when the right button is pressed. This generally matches the F key assignment and the contents of menu bars "File" and "Edit". Operation of the F keys has a special significance. Since the user interface must primarily be available for the machine, an important requirement is comfortable operation using the F keys.

14 2-2 Operational Concept Machine Data Management Keyboard Operation is similar to the processes commonly applied under Windows. Use cursor keys to navigate and select or execute commands by pressing the <space bar> or the <ENTER> key. Additionally, the shortcut <Shift>+<F10> opens a pop-up menu consisting of a process selection that generally matches the F key assignment and the contents of menu bars "File" and "Edit". 2.2 Projekt Navigator View1 The Project Navigator (PN) is used for navigation and to operate the machine data. The mouse or the keyboard is used for operation within the PN. For the machine data, three different PN displays are possible: Baum und Liste_gr.bmp Fig. 2-2: Tree and list (default setting)

15 Machine Data Management Operational Concept 2-3 View 2 View 3 Fig. 2-3: Tree Baum_gr.bmp Fig. 2-4: List Liste_gr.bmp All node points, with the subordinate nodes, determine the structure of the machine data and thus the structure of the tree. The subordinate nodes of a node in the tree are displayed in the list. In addition to the previous views, a view with the node for the current data is introduced here. This displays the current data in the control. Using a selection, the current machine data can be displayed. With the selected page, the ONLINE data values can be modified in the NC if authorization has been granted.

16 2-4 Operational Concept Machine Data Management Configuration View Fig. 2-5: The tree in the configuration view Konfigurationssicht.bmp Machine data are assimilated within the parameter tree data structure. In addition to other nodes within the first level, there is a node "Machine data", which contains the two subnodes "System machine data" and "User machine data". OEM and user pages are incorporated into the latter with equal rights, with no other differences. A differentiation between OEM and user does not apply. Page number determination: System pages: 1-99 User pages: To improve the overview and editing of the data amounts, each page has a Properties dialog box: page designation (modifiable only for user pages) control variable designation (if present) value range of control variable (changeable) System pages are displayed only in the Configuration view (not in the Data and Structure views).

17 Machine Data Management Operational Concept 2-5 Structure View Data View Fig. 2-6: Displaying the tree in the structure view Struktursicht.bmp Only User pages are displayed within the Data/Structure views. Within the Structure view, the current machine data can be accessed using the node indicated with CNC (Current parameter record). Fig. 2-7: Displaying the tree in the data view Datensicht.bmp

18 2-6 Operational Concept Machine Data Management Note: Only User pages are displayed. Newly generated machine data blocks that contain only system pages are empty in the Data and Structure views! 2.3 Information on Language Switching After the language is switched, text may not be displayed in the desired language or by "???". This occurs when not all the texts are in the currently set language. While the texts of the system pages are already available in the particular languages, they still have to be translated in the pages you have created yourself (page numbers 100 and greater). Note: Special pages (User pages prepared by Bosch Rexroth for special functions) having page numbers above 100 are already present in the "\BasicData\DataMTC\Madat" directory in the form of export files in the installed languages. In order to use the corresponding texts, these files must be imported. Procedure for translating texts after switching the language (in the Setup menu): A file with the texts of Bosch Rexroth System pages is created automatically and is already present (it is supplied during the installation of the languages). If no texts in the set default language are found for a User page, the German texts (if present) are used. If no German texts can be found either, the system attempts to load English texts. If this also fails, three question marks ("???") appear in the display instead of the text. To translate User page texts from one language to another, the page is loaded into the Structure Editor. The corresponding texts can be adapted here. The following example shows a User page for which no texts are present in the set language (English). Instead, the German texts are displayed.

When a machine data block is stored, the language in which it was loaded is always saved on the PC.

21 Machine Data Management Working with Machine Data Blocks Working with Machine Data Blocks 3.1 Basics In the beginning, a newly created parameter block contains an empty "Machine data" node. Fig. 3-1: Empty Machine data node Leerer Knoten Maschinendaten_gr.bmp 3.2 Creating a New Machine Data Block The New function generates a machine data block that contains only the System pages. Fig. 3-2: Creating a new machine data block Maschinendatensatz Neu_gr.bmp

22 3-2 Working with Machine Data Blocks Machine Data Management After the New function is carried out, the following appears: Fig. 3-3: Newly created machine data block Neuer Maschinendatensatz_gr.bmp The newly created subnodes of the Machine data node now appear in the List view on the right side. The "System machine data" subnode contains the System pages. The "User machine data" subnode is empty. Here, the New function can be used to define your own pages or to import existing pages in EXP format using the Import function. Furthermore, pages can be pasted using the Copy/Cut/Paste functions. The following figure shows a machine data block that contains both System pages and User pages: Maschinendatensatz mit aufgeklappten Subknoten_gr.bmp Fig. 3-4: View of a machine data block with opened subnodes

23 Machine Data Management Working with Machine Data Blocks Deleting a machine data block CAUTION Data is deleted! The function irrevocably deletes a selected machine data block after a safety prompt! o not delete any data blocks that may still be needed! If in doubt, ask the system administrator. Maschinendatensatz löschen_gr.bmp Fig. 3-5: Delete machine data block Maschinendatensatz löschen Sicherheitsabfrage_gr.bmp Fig. 3-6: Safety prompt when deleting a machine data block

24 3-4 Working with Machine Data Blocks Machine Data Management Note: The current machine data block cannot be deleted. It is always a representation of the machine data block located in the control. 3.4 Transferring a Machine Data Block General Information Note: Machine data are always transferred with the associated parameter block. Accordingly, the download of a parameter block is always linked to the transfer of the associated machine data! The function Download loads a complete machine data block (incl. all pages it contains) into the control. This procedure is necessary after an alteration to page structures of the current machine data block in the PC, for loading a different machine data block into the control, for loading a machine data block into the control for the first time. CAUTION Current variable contents are deleted! Ÿ After a complete machine data block has been transferred, the control re-initializes all the variables of pages whose structure was altered. Differentiation is made between the following cases: Download of a complete machine data block to the control (types and definitions). Optional transfer of data by the user according to specifications. Fig. 3-7: Machine data download with or without values Dialog Download Maschinendatenwerte.bmp Upload of a complete machine data block from the control (types, data and definitions). Download of the contents of all the machine data elements of a page in the control. The machine data block, as well as every page definition, has its own ID. If a concordance of the page ID is ascertained during the download, the structure definition of this page is not transferred. Data are always transferred if this was specified in the selection dialog box (see fig. 3-7: Machine data download with or without values).

26 3-6 Working with Machine Data Blocks Machine Data Management Download Bestätigung Werte übertragen.bmp Fig. 3-9: Machine data download, structures of machine data block are already in the control If NO is pressed when the machine data block is active, the procedure is terminated (page structures are already in the control). If YES is selected, the page data are loaded into the control. It is possible to carry out a specific download of the data of individual pages using the Download on Page Level function. If the machine data record is inactive, the machine data record structures will always be loaded into control. In this case, machine data values can be transferred optionally (see Fig. 3-11). Note: Parameter download is started automatically if no parameters are in the control. Download after a parameter download By default, the associated machine data are loaded to the control after a parameter download. If the associated machine data are already in the control (machine data block is ACTIVE) and, in addition, if the contents of data elements were not modified, the procedure is terminated after the parameter download is complete. If only the data values of the machine data were modified, a query appears asking whether the modified data are to be transferred: Fig. 3-10: Download of modified data Dialog Download geändeter Maschinendatenwerte.bmp Otherwise (machine data block is NOT ACTIVE), the machine data structures are downloaded. Before the download is started, it is possible

27 Machine Data Management Working with Machine Data Blocks 3-7 to decide whether only the page structures or also the contents of the data elements (values) are to be downloaded.

During upload, the complete machine data block (data and definitions) will be read from the control.

29 Machine Data Management Working with Machine Data Blocks 3-9 Fig. 3-14: Machine data upload Maschinendaten Upload_gr.bmp If the machine data block is also ACTIVE in the corresponding active parameter set (identified by two opposite arrows ), the current data will automatically be transferred. In the other case, there are structural differences between the current machine data block and the machine data block which belongs to the active parameter set (e.g. because of a modification of a page definition after a machine data download or by addition of a new user page). The identifications of both machine data blocks are therefore different. In this case, a safety prompt if the available machine data block must be overwritten, occurs. Maschinendaten Upload Sicherheitsabfrage_gr.bmp Fig. 3-15: There are structural differences between the machine data block of the active and the current parameter set. If the request is acknowledged with YES, the current data (definitions and values) will be transferred from the control. The modifications that are made, will be lost.

30 3-10 Working with Machine Data Blocks Machine Data Management Note: If for some reasons the machine data block was deleted from the active parameter set, it is created newly during upload. 3.5 Copying/Cutting/Pasting a Machine Data Block The functions Copy and Cut always refer to a complete machine data block (data and definitions). It is possible to paste a machine data block only into an empty machine data node. Note: Using the functions Copy/Paste, it is easy to create a backup copy of a machine data block. The following figures show the flow of a Copy/Paste operation: Fig. 3-16: Copy machine data block Maschinendatensatz Kopieren_gr.bmp

31 Machine Data Management Working with Machine Data Blocks 3-11 Fig. 3-17: Pasting a machine data block After pasting is complete, the following situation results: Maschinendatensatz Einfügen_gr.bmp Fig. 3-18: Situation after Copy/Paste Maschinendatensatz nach einfügen_gr.bmp The machine data block of the original parameter block 01 (MyFirstParameterSet) remains unchanged. A copy is pasted into parameter block 02 (MySecondParameterSet).

32 3-12 Working with Machine Data Blocks Machine Data Management On the other hand, the Cut/Paste sequence results in the following situation: Fig. 3-19: Cutting a machine data block Maschinendatensatz Ausschneiden_gr.bmp Fig. 3-20: Inserting a machine data block Maschinendatensatz Einfügen_gr.bmp

33 Machine Data Management Working with Machine Data Blocks 3-13 Fig. 3-21: Situation after Cut/Paste sequence Maschinendatensatz nach Ausschneiden-Einfügen_gr.bmp As the figure above shows, the cut machine data block is deleted from parameter block 02 (the Machine data node is empty) and is pasted into parameter block 01 (the previously empty Machine data node now contains the two subnodes System machine data and User machine data). 3.6 Importing/Exporting Machine Data Blocks Exporting a Machine Data Block Entire machine data blocks can be exported and then imported. Fig. 3-22: Exporting a machine data block MDS Export_gr.bmp

34 3-14 Working with Machine Data Blocks Machine Data Management Importing a machine data block The exported machine data block is saved in the selected directory with the file extension.mds. If there is already a machine data block with the same name, a query appears asking whether the existing data block is to be overwritten. If not, it is possible to change the name of the block to be saved. There are two different situations when a machine data block is imported: A machine data block is already present A machine data block is not already present In the second case, a machine data block is created by the import. If a machine data block is already present, an attempt is made to import the data of the individual pages of the machine data block. If errors occur here (the exported machine data block has more pages than the existing one or the page structures do not agree), this is indicated in a dialog box and the data import for this page is cancelled. If errors occurred, these are listed after the import is terminated. The contents of this list can be transferred to the clipboard and then processed further from there (e.g. printed after being transferred to a word processing program). IMPORTANT Ÿ If a machine data block that contains pages that are not in the import machine data block is already present, these are not modified. However, no message appears. MDS Import_gr.bmp Fig. 3-23: Importing a machine data block Before page data are imported in an already existent machine data block, it is possible to decide for every individual page whether the data are to be transferred or not.

37 Machine Data Management Working with Machine Data Pages Working with Machine Data Pages 4.1 Creating a New Page After a dialog box appears in which the user enters the number and name of the new page, the structure editor is started for definition of the new page. Fig. 4-1: Create new user page Page-Neu_gr.bmp After the New function is selected, the following dialog box appears: Page-Neu-Dialog_gr.bmp Fig. 4-2: Dialog box for entering the description and number of the new page

38 4-2 Working with Machine Data Pages Machine Data Management The description of the new page is entered in the field "Page description". Note: Entering a description for the page is obligatory. The field "Page description" must not be empty! The "Page number" list box shows the list of available page numbers that can be assigned to the new page. The lowest available page number is set by default here. After finishing the dialog, the "Structure editor" is started for processing the new page. The required entries can be made here (see chapter 7 "The Structure Editor"). 4.2 Deleting a Page The function Delete always refers to a complete page (data and definitions); it is permitted only on the level of User machine data. Before the deletion itself, the safety prompt: "Should the page be deleted?" appears in a dialog box. Fig. 4-3: Delete page Page loeschen_gr.bmp WARNING Page deletion The function irrevocably deletes a selected page after a safety prompt.

39 Machine Data Management Working with Machine Data Pages Changing the Properties of a Page Using the Properties dialog box of a User page, it is possible to change the page designation. As a rule, this is impossible for System pages! Fig. 4-4: Properties dialog box of a User page Dialog Page Eigenschaften_gr.bmp Furthermore, the Properties dialog box permits control variable values to be changed. The page number is displayed for user informational purposes only.

40 4-4 Working with Machine Data Pages Machine Data Management 4.4 Changing the Page Structure Note: This function is available only for User pages. For a 1-step UNDO, the page is saved beforehand in export file format in the current Windows TEMP directory. (UNDO using import.) Fig. 4-5: Modify page Page Aendern_gr.bmp The page is loaded into the structure editor for processing (see chapter structure editor) After the Structure Editor is exited by pressing Finish, the modified page is used; the existing page structure is replaced by the modified page. Note: Structural modifications to a page lead to deleting of existing data values.

41 Machine Data Management Working with Machine Data Pages Copying/Cutting/Pasting a Page Copy/Paste The function Copy always refers to a complete page (data and definitions). A copied page can be pasted any number of times. If there is a page with the same page number is already present in the list of User machine data, it is possible to overwrite the existing page. If this is not desired, the page can be pasted under one of the page numbers that are still available. Page kopieren_gr.bmp Fig. 4-6: Copy page Page einfügen_gr.bmp Fig. 4-7: Pasting a page

42 4-6 Working with Machine Data Pages Machine Data Management If a page with the same page number is already present, this can be overwritten: Fig. 4-8: Dialog box for overwriting an existing page Dialog Page überschreiben_gr.bmp or the new page can be pasted under one of the available page numbers. Dialog Page einfügen unter freier Nummer_gr.bmp Fig. 4-9: Pasting the new page under an available page number

43 Machine Data Management Working with Machine Data Pages 4-7 Cut/Paste The function Cut always refers to a complete page (data and definitions). A cut page can be pasted only once. If there is a page with the same page number is already present in the list of User machine data, it is possible to overwrite the existing page. If this is not desired, the page can be pasted under one of the page numbers that are still available. If pasting is not executed after cutting, the action has no effect. 4.6 Printing a page The selected page is printed directly using Notepad on the default printer in the export file format. Fig. 4-10: Print page Page Drucken_gr.bmp During printing, the page is displayed in the export file format in Notepad.

45 Machine Data Management Working with Machine Data Pages Exporting/Importing a Page Export data flow The export function permits the user to save individual pages of a machine data block as an ASCII file on any drive/directory. The export file contains both data definitions as well as texts and variable contents: *:Exp (3) DEF (1) DAT (2) Page 1 Page 1 Page 2 Page 2 Page... Page... (4) DEF DAT Page 1 Page 1 Page 2 Page 2 Page... Page... (1): DEF: Structure definitions (2): DAT: Data values (3): Parameter block x (4): Parameter block y Fig. 4-12: Export dataflow Export2_gr.wmf Import data flow Importing page data: During data import, the interface checks the agreement of the definitions. If they agree, the data are accepted; any already existing values are overwritten! Importing page definitions (in Configuration view only): If no page with the corresponding number yet exists, it is created. If a page with this number is already available, it can be replaced by the new page or the new page can be saved under an available page number.

The generated file obtains the file name suffix "EXP" (for "export" file) by default. Note: Exported pages can be read back into a machine data block using the Import function. The export of a page includes both its complete structure and all the variable values that have already been stored/altered. Example of an export file Export of the System page 001 "Spindle setup register". Lines beginning with the character ";" are interpreted as comment lines by the system. They are ignored during import. Words in bold and italics are keywords must not be changed!

48 4-12 Working with Machine Data Pages Machine Data Management CAUTION Inadvertent alterations to file contents! Text processing programs often use their own file formats and control characters in order to store a loaded text. This may make it impossible to import the export file! Use only ANSI editors (e.g. notepad) to modify the contents of the export file. Explanatory notes on the individual file sections Info for internal management: Specific information Character set with which this file was exported List with the possible types of variables Association between type of variable and corresponding identifier. The identifier is used in the file section "Variable contents of the containers" under the column "Type". Defined variables: Number and name of the page. Is used during import for the automatic default of the target page. List with all the variables used in the page. Here the variable designation, variable type and protection against access are entered. The order in which the variables are listed automatically determines their variable number (first list entry: Var. No. 0001; second list entry: Var. No etc.). Note: The abbreviations "NC", "PLC", "UI" and "PwUI" are applicable for access protection. If the variable is protected against access, the text "No" is indicated in front of the abbreviation. Example: NC write access permitted: NC NC write access blocked: NoNC Defined containers (structures): Definitions of the control variables used for addressing a container. In the example, the control variable 1 (CV1) corresponds to the number of the spindle axis in the system(1 to 32); CV2 is not used here. By means of the data in this section, you see what effect the association of a machine data block to a block of machine parameters has: in the block of machine parameters, axes 1 to 6 are configured as spindle axes to address the containers (a specific structure within a field), the system uses CV1 in areas 1 to 6. The same page structure can be used for a different system configuration. The data for spindles applied there is then in different containers. Variable contents of the containers Several subsections may be included in this file section. Every subsection contains variables and appertaining values of a specific container. The variable number at the beginning of the line is important. It contains, so to speak, the reference to the corresponding variable declaration in the section "Defined variables". The variable which is entered there, e.g. in the 2 nd line ("Jog speed rapid"), must include the value "0002" as the variable number in the corresponding subsection. In the example above, values are assigned only to the variables of container No. 5 (CV1:0005 / CV2:0000. All the other variables include the

49 Machine Data Management Working with Machine Data Pages 4-13 character "-" as the value. The character "-" causes the corresponding variable to be ignored when the page data is later transferred from the PC into the control. In this manner, the old variable value is maintained in the control. Note: During import of a page, all the variable values (including the character "-"!) are transferred to the target page and overwrite any already existing values. If existing values are not overwritten, the corresponding data lines of a subsection must be deleted. Import Using the Import function, a page (data and definitions) is downloaded out of an ASCII file and pasted depending on its number in the list of existing User pages. Page Import_gr.bmp Fig. 4-14: Import page function The page to be imported is selected using a file selection dialog box.

54 4-18 Working with Machine Data Pages Machine Data Management 4.9 Control Variable Handling In order to display variables of other containers of the current page, the values of the available control variables must be set accordingly. The F keys (CV+, CV-), the pop-up window and the menu bar permit stepwise modification upwards (current index +1) or downwards (current index -1). In addition, function key CV selection can be used to open a dialog box that permits the control variables to be set directly using combo boxes (for each existing control variable). The page s Properties window also permits this. After they are opened, the input windows of the two combo boxes display the current values of the control variables.

In this case, the input dialog box serves only as a data display. The title bar of the input dialog box contains information about the page number and the page designation, as well as the index and designation of the selected data element. The current value of the data element is displayed in the input window. In addition, the dialog window contains information about the permitted minimum and maximum values of the data type. In the case of data elements of the type "basic_unit", it is possible to select between metric and Imperial units.

A variable can be inserted instead of a constant. All above-listed parameters are always to be indicated. The declared parameters must lie within the given value range. The NC checks their validity first during operation. The NC interrupts the program execution and initiates an error message if a declared parameter lies outside of the valid value range. The NC reacts in the same way if the user writeaccesses a write-protected data element from the NC program. The NC automatically limits the value to the lowest or largest value of the data element if the user declares a value outside of the valid value range for a data element.

61 Machine Data Management Access to Machine Data using Program PLC Syntax Function Blocks for Accessing Machine Data The 'MTD_RD' function block enables the PLC program to read machine data. Provided that the PLC program has enabled access, the 'MTD_WR' function block can be used for writing to the machine data. The machine data is kept in the CNC. The PLC must therefore access this information as required, i.e. serially. Thus, the machine data will be available after one PLC cycle at the earliest. The function block interfaces are exactly defined. When a function block is called, the programmer merely has to 'connect' the individual signals.

62 6-4 Access to Machine Data using Program Machine Data Management Method of Operation Timing of writing machine data: WRITE M data READY (1) Setting the "WRITE" input initiates the transfer of the machine data. The machine data that is to be accessed is defined by the 'PAGE', 'VAR1', 'VAR2' and 'ELEMENT' inputs. The "TYP" input defines the type of the machine data. Automatic conversion is performed if the specified data does not exist in the specified format. (2) The active "READY" output indicates that the transfer of the machine data is completed. In a write process, the "READY" output shows that data transfer has been completed. (3) In a single data exchange, the "WRITE" input may now be cleared. (4) Clearing the "WRITE" input also clears the "READY" output of the function block. (5) If the "WRITE" input remains statically ON, a new data transfer is automatically initiated once the old data transfer has been completed. This enables tool data to be written cyclically. Timing of reading machine data: READ M data READY (1) Setting the "READ" input initiates the transfer of the machine data. The machine data that is to be accessed is defined by the 'PAGE', 'VAR1', 'VAR2' and 'ELEMENT' inputs. The "TYP" input defines the type of the machine data. Automatic conversion is performed if the specified data does not exist in the specified format. (2) The active "READY" output indicates that the transfer of the machine data is completed. In a reading process, the 'READY' output shows that the requested data are available. (3) In a single data exchange, the "READ" input may now be cleared. (4) Clearing the "READ" input also clears the "READY" output of the function block. (5) If the "READ" input remains statically ON, a new data transfer is automatically initiated once the old data transfer has been completed. This enables machine data to be read cyclically.

A control variable is considered to be undefined if no text is provided in the designation. For the first control variable, the identifier is preassigned with the "Standard" name. It is often necessary to parameterize a function by way of the variables included in a container. If this function is to be set on the machine in a manner specific to the axis, spindle or process, the control variable types IP_AXIS (for feed axes) SP_AXIS (for spindle axes) PROCESS (for processes) or AXIS_DES (for feed and spindle axes) can be used. By this means, the system creates several containers which depending on the set control variable type are in each case assigned exactly to a feed axis, spindle axis or process. The number of containers actually required (e.g. the number of feed axes on the machine) does not have to be known for this purpose.

74 7-10 The Structure Editor Machine Data Management Note: The POS, VELO, ACCEL, FEED/REV, CON_SURF_S and PERI_SPEED types of variables should be used only in conjunction with a control variable of the types IP_AXIS, SP_AXIS or AXIS_DES. On the other hand, control variable type NO_CLASS is to be used if no reference to existing axes, spindles or processes is necessary. Note: When determining the minimum and maximum values, pay attention that the page size is limited to 64 kb. If both control variables are used (CV1 and CV2), a 2-dimensional container field is generated. The number of rows and number of columns are then determined by the initial and end values of a control variable. Both control variables are needed for addressing a container from the 2- dimensional container field, the one specifying the row and the other the column. Control Variable 1 Fig. 7-13: Dialog box for defining control variable 1 StrukturEditorLV1.bmp The designation of control variable can be defined freely (may. 28 characters). The possibility exists to enter a nickname which is displayed on the corresponding Fkeys for the control variable with a max. of 8 characters in the Fkey text field. The data type can be selected via a combo box. The limits can be determined for control variable of type NO_CLASS in the range of to The limits are firm defined for control variables of process or axes type. In addition to the description of the control variable description, its type and the definition range of the control variables, it is possible to enter descriptive texts for control variables of type NO_CLASS. You can show the user additional information for every value of the control variable (e.g. what is affected or set by the control variable) by means of the "extended

The following edit functions are available for processing the texts: Highlight/delete entry Cut/paste entry Copy/paste entry Note: The definition of the first control variable is obligatory. Defining a second control variable is optional. The remaining input fields will be enabled by entering a designator. Note: An available second control variable will be deleted by deleting the designator. If PROCESS or an axis type is used for the control variable type, the process or axis descriptions are displayed as additional texts. These have informational purposes only and cannot be edited.

Note: Extended selection texts If data sets are generated on the PC from the data of a connected control online (upload), existing "extended selection texts" are not transferred to the PC. Transfer of these texts is possible with export import. Export can be used for saving the extended selection texts. The field F key text permits a nickname for the control variable to be entered (max. 8 characters); this is then displayed on the corresponding F keys.
