15 Programming Integrating the function block in the user project Creating the FB instance in the user project The _FTA_control function block is a component of the command library of the SIMOTION SCOUT engineering system. In order to work with the block, you must create an instance of the function block and a struct_fta_scaledata type variable in the user project. Example: VAR_GLOBAL myfta_control : _FTA_control; // create instance of FB _FTA_control myscaledata : struct_fta_scaledata; // structure with all scale data END_VAR Note If you want to control more than one weighing module, you must create a new variable for the data structure and an instance of the function block with a new name in the user program for each weighing module used. Function Manual, 03/2009 Edition 15

16 Programming 2.1 Integrating the function block in the user project Call (LAD representation) Application example The application example is included on the "SIMOTION Utilities & Applications" CD-ROM and is available for various SIMOTION hardware platforms. The "SIMOTION Utilities & Applications" CD-ROM is provided free of charge and part of the SIMOTION SCOUT scope of delivery. 16 Function Manual, 03/2009 Edition

17 Programming 2.2 Addressing the SIWAREX FTA weighing module 2.2 Addressing the SIWAREX FTA weighing module Overview Communication between the SIMOTION device and the SIWAREX FTA weighing module takes place by means of direct I/O access and data record transfer. Creating I/O variables For cyclic data transfer, you must create one I/O variable for the I/O inputs and one I/O variable for the I/O outputs in the symbol browser. This I/O variable must have the address of the weighing module of data type BYTE and a field length of 16. When creating the I/O variable, enter the configured address from the hardware configuration in the "I/O address" parameter (see example below). Example Determining addresses from HW Config: Figure 2-1 Addresses in HW Config Creating the I/O variables in the symbol browser: Figure 2-2 Addressing with I/O variables Function Manual, 03/2009 Edition 17

18 Programming 2.2 Addressing the SIWAREX FTA weighing module Parameter transfer The I/O variable for the I/O inputs is transferred to the periin input parameter. The prepared data for the I/O outputs are supplied by the function block at the periout output parameter. These data are assigned to the I/O variable for the I/O outputs. Note For additional information, refer to: SIMOTION SCOUT online help Programming Manuals for the relevant programming language, such as: SIMOTION ST, Structured Text Programming Manual SIMOTION MCC, Motion Control Chart Programming Manual SIMOTION LAD/FBD, Ladder Diagram and Function Block Diagram Programming Manual These documents are shipped with SIMOTION SCOUT in electronic form. 18 Function Manual, 03/2009 Edition

19 Parameter assignment _FTA_control function block Task The _FTA_control function block (FB) enables you to control the SIWAREX FTA weighing module in the SIMOTION automation system. The _FTA_control FB writes process data cyclically to the weighing module and reads the status of the weighing module cyclically. The status is made available at the output parameters of the FB. On request, the FB writes scale data to the weighing module and reads scale data and process status from the weighing module. The scale data and process status are stored by the function block in the Struct_FTA_scaleData data structure and read by the function block from this data structure.

The SIWAREX FTA weighing module updates the values for the val1process / val2process parameters internally in a 10 ms cycle. Each time the values are updated, the weighing module increments the value for the cntrrefresh parameter. The _FTA_control function block reads the values in cycles from the weighing module in the time scale of the calling task (e.g. BackgroundTask) and updates the values in the output parameters cntrrefresh, val1process / val2process. The value in cntrrefresh can be used like a time stamp in the SIMOTION device. val1process OUT REAL 0.0 Outputs the selected process parameter (e.g. net weight); selection is made in DR7 val2process OUT DWORD 16# Outputs the selected process parameter (e.g. AWI status); selection is made in DR7 scalestatus OUT DWORD 16# Outputs the status of the non-automatic scale startup OUT BOOL FALSE TRUE = restart of the SIWAREX FTA weighing module Communication and command execution are not possible 1) Parameter types: IN = input parameter, IN/OUT = in/out parameter, OUT = output parameter 2) Description of system functions _writerecord and _readrecord see Parameter Manual SIMOTION system functions/variables for devices.

22 Parameter assignment 3.1 _FTA_control function block Function description When the _FTA_control FB is called, the cyclic data of the FB are read and written. Command execution is started on a rising edge on input parameter execute. The command is selected by specifying the command number in input parameter cmdnumber. For the command groups with numbers , one or more data records (DR) are transferred to or read by the SIWAREX FTA weighing module. When a command is started, the output parameters busy = TRUE and done = FALSE are set. Output parameters error, errorid, erroridcommand, and errroridtransfer are reset. When the command has been executed without errors, the following parameters are displayed: busy = FALSE, done = TRUE, and error = FALSE. If an error occurs during command execution, the following output parameters are set busy = FALSE, done = FALSE, and error = TRUE. The error is specified in output parameters errorid, erroridtransfer, and erroridcommand. A new command can only be started once execution of the commands is complete (busy = FALSE). If a new command is started while commands are being executed (busy = TRUE), the new command is ignored. Note You can find an overview of the command groups and commands in the appendix. If the SIWAREX FTA weighing module generates a new error message, the following output parameter is set: errorfta = TRUE. The error message is specified in output parameters errortypefta and erroridfta. After the error message has been evaluated, it must be acknowledged with a rising edge on input parameter ackerrorfta. The output parameters errorfta, errortypefta and erroridfta are reset by the _FTA_control function block in the process. 22 Function Manual, 03/2009 Edition

24 Parameter assignment 3.1 _FTA_control function block Task integration (call) The _FTA_control function block is designed to be called in a cyclic task and must be called in this task during each task cycle. It may take several cycles for a task to be executed. The user decides which cyclic task of the _FTA_control function block the call is made in. No limitations are placed on the functionality of the _FTA_control function block. The call can be performed in all cyclic tasks. A fixed time scale (e.g. IPOSynchronousTask) is not required for the processing. Error messages When an error occurs, an error specification is displayed in output parameter errorid. If an error has not occurred, errorid has the value "16#0000". The errorid output parameter remains present until the error is corrected. The errorid output parameter is reset with a rising edge on input parameter execute. Table 3-2 Error numbers in output parameter errorid Error no.

61 Parameter assignment 3.3 Weight display with calibration capability 3.3 Weight display with calibration capability Overview The value for the weight display with calibration capability is formed internally by SIWAREX FTA, encrypted and made available to the user in the DR35 data record. Function description The DR35 data record is read using the _FTA_control function block and stored in the Struct_FTA_scaleData data structure in the DR35 element. The DR35 and DR39 data records and the winccocxwrite element of the Struct_FTA_scaleData data structure are used to ensure reciprocal monitoring of the "SecureOCX" add-on and the SIWAREX firmware. The version number (ID) of the weight display with calibration capability used has to be entered in the DR39 data record (see table below). Table 3-29 Version numbers of weight displays with calibration capability Display used WinCC flexible 2005 WinCC flexible 2007 WinCC flexible 2008 Version number V0.2.1 V0.2.2 V0.2.3 The "SecureOCX" add-on for WinCC flexible, a special function which is able to decipher the content of the DR35 and display it in a special output field is used for evaluating. "SecureOCX" has to be installed in addition to WinCC flexible. Note Refer to the SIWAREX FTA Electronic Weighing System for Automatic Scale Manual for details of how to install and configure the weight display with calibration capability in WinCC flexible and which visualization devices can be used. This documentation is included in the SIMOTION SCOUT scope of supply as electronic documentation! Error messages If the data received are incorrect, "ERROR 1" is output. If the DR35 data record is not updated (monitoring time approx. 2 s), the text "ERROR 2" appears on the display instead of the weight value. Errors in the reciprocal recognition of the SIWAREX firmware and "SecureOCX" produce ERROR 3, if regulations = OIML is set. When regulations = ----, the current weight value is displayed. Function Manual, 03/2009 Edition 61
