3-1 Commissioning Software SIWATOOL V4 Note: All data should be read into PCS7 after the scale has been adjusted with SIWATOOL. Data inside SIWAREX FTA will then be synchronized with data in the PCS7 project. 3-5 10 4 Description of the function blocks 4.1 Function block SftAwi The block is used for controlling a SIWAREX FTA module. Data is transferred cyclically via the I/O interface and different data records are read from the module or transferred to the module acyclically. The message queue for the module is read out continuously and corresponding WinCC messages are issued. For a detailed description of the SftAwi block and important information, please refer to the chapter SftAwi driver block inside the file MANUALS MANUALS_PCS7 SftAwi_manual_eng.chm on your software disc or open the online help via F1 in SIMATIC Manager Data-Record structure of SIWAREX modules All parameter of SIWAREX modules are structured in data records (DR).
These DR need to be read or written from the SIWAREX into the PLC or from PLC into SIWAREX with special command codes (see SIWAREX FTA manual). A DR can only be read / written completely! It s not possible to read or write only a single parameter within a DR! Therefore the following steps are recommended in order to read / write parameters from / into the SIWAREX module: Example: The module is running in Automatic mode and a limit-value should be changed: The limit-values are within data record 4 (see SIWAREX FTA manual). As it is not sure, that the data of DR4 in the CPU are the latest, it s recommended to read DR4 first from the SIWAREX module into the CPU first. In Automatic mode the function block CMD_AWI can be used to execute this (and all other) command in a very easy way: The input parameter RD_DR4 needs to be set TRUE. Afterwards the DR4 is read from the SIWAREX into the CPU.

After that the desired limit-value can be edited directly on the function block SftAwi. At the end the modified DR4 must be written back into the SIWAREX FTA module. This can be triggered by a positive edge on the input parameter WR_DR4 of the CMD_AWI command block. 14 5 Description of the Faceplates 5.1 General 5.2 Typicals Operation and monitoring of the scale via WinCC faceplates is described below. Descriptions of the individual scales parameters and scale functions are provided in the SIWAREX FTA manual and are not explained individually where each faceplate is displayed.
The example faceplate for the SIWAREX FTA modules was created with the Faceplate Designer. The WinCC images can be modified according to individual requirements. Every time a new view is opened, the displayed parameters are refreshed automatically. The displayed parameters can be updated at any time by clicking the 'Receive Data' button as well. Note: After compiling the OS the OS project editor needs to be run once.
