  • Page 18: Product Overview

    Automatic scale operation is characterised by an weighing procedure performed automatically according to a defined plan. The function module (FM) SIWAREX FTA is integrated in SIMATIC and uses all features of the modern automation system such as integrated communication, diagnostics system and project planning tools to its advantage.

  • Page 19: A Pplication

    Material loading with totalising 3.4 Structure SIWAREX FTA is a function module (FM) of the SIMATIC S7-300 and can be read directly on the SIMATIC S7-300- or ET 200M bus board. Installation / cabling efforts for the 80 mm wide module are simplified with the profile rail assembly (snap-in technology).
  • Page 20 Product Overview 3.5 Function The primary task of the SIWAREX FTA consists of the precise measurement of the current weight values in up to three measurement ranges and the exact control of the weighing procedure. The control of the weighing procedure is completely run from the weighing module as if in separately constructed weighing electronics.

  • Page 21: Simatic

    Areas of application SIWAREX FTA in the production chain 3.6 System Integration in SIMATIC SIWAREX FTA is completely integrated in the SIMATIC S7 and SIMATIC PCS7. The user is absolutely free to configure his automation solution including the weighing application as desired. The optimal solution can be created for small, medium and large systems by selectively combining the SIMATIC components.

  • Page 22: S Ervice With Siwatool Fta

    During service procedures, you can analyse the processes in the scale and test them with the help of a PC. Reading the diagnostics buffer from the SIWAREX FTA is very helpful in analysing events. Besides complete access to all parameters, memory or print-outs of the weighing file, the program can create weighing curves as well.
  • Page 23 A trace mode exists in the SIWAREX FTA module for optimising weighing progress. The recorded data can be displayed in a curve diagram using the MS Excel.

  • Page 24: D Ownload With Siwatool Fta

    The weighing logs are stored on an MMC (Micro Memory Card) that is inserted into the SIWAREX FTA for the period of time defined in the weights and measures act. If a person disagrees with the results of a certain weighing procedure, the weighing data for that weighing procedure can be reconstructed from the MMC memory.

    For configuration, assembly and commissioning, the definitions from the manual for the SIMATIC S7 300 system are applicable. This chapter provides you with additional information for hardware configuration and assembly, and for preparing the SIWAREX FTA for operation. The technical safety information is to be strictly adhered to. Warning Unqualified intervention in the device/system or not adhering to the warning notices can result in serious injury or damage to equipment.

    If function expansion in the new firmware results in new internal data structures, new data records or changes within existing data records then the SIWAREX FTA assigns the parameters with default values after the download. Therefore, the original parameter status is read using the SIWATOOL FTA (“Communication...
  • Page 189 Downloading Firmware with SIWATOOL FTA Warning notice During the firmware download, SIWAREX FTA do not respond to communication requests from the SIMATIC CPU. The CUP indicates the peripheral access error and if no respective organization block (OB) is programmed then the CPU can go to STOP.
