    The user enters the desired log ID in DR 46 and then sends DR 46 to the SIWAREX FTC. A short time later, the log is prepared for reading (Status bit „MMC data ready S7). If the user now requests the DR 47 with the log, the log with the desired ID is read in DR 47.

    The trace function is used for logging measurement values and current states of the scale in RAM memory of the SIWAREX FTC or in the MMC card. When logging to RAM, SIWATOOL FTC reads the trace elements with data record 120 and when logging to the MMC it is done through data record 121.

    An element requires 46 bytes. If the recording is run e.g. once per 50 msec, it means memory requirements of 920 bytes per second. In the simplest case, the RAM memory (approx. 2 MB) of the SIWAREX FTC can be used for the recording.

    Every command has a unique number. A command can be sent via various interfaces (SIMATIC, SIWATOOL FTC, digital input). Every time that a command is sent to SIWAREX FTC, a check must be made for whether the command has been executed correctly. The data and operating errors (synchronous errors) that are generated provide information on why the command could not be executed.

    Hardware Configuration. SIWAREX FTC is projected as a function module in the SIMATIC manager. In order for the SIWAREX FTC to be accepted into the module assembly catalogue of the SIMATIC manager, the SETUP program (SETUP_FOR_SIMATIC on the project planning package CD) or hardware update by HSP (hardware support package) must be executed.

    SIWA_ FTC. While programming the call, an instance data block is created for the FB SIWA_FTC. Besides the instance data block, a scale DB is required for every SIWAREX FTC scale, in which the scale parameters are stored. The UDT that comes with it can also be used for creating the scale DB.

  • Page 126: Db_Scale:= 18, Input, Int

    A scale DB must be defined for every scale, in which the parameter of the SIWAREX FTC and the current actual value are found. The number of the DB can be freely selected. DB15 has been defined as the scale DB in the project planning package.
