Weighing module SIWAREX FTA

Description

SIWAREX FTA is a calibratable and versatile weighing electronics for SIMATIC S7, C7 and PCS7. It can be used for automatic and non-automatic weighing, e.g. for the production of mixtures, filling, loading, monitoring and bagging. The SIWAREX FTA function module is integrated in SIMATIC S7/PCS7, and uses the features of this modern automation system, such as integral communication, diagnostics and configuration tools.

By setting a parameter in SIWAREX FTA, one of the following scale types can be activated:

  • NAWI (Non Automatic Weighing Instrument) conforming with OIML R76
    For example: Hopper weighing, Fill level scale, Platform scale, Crane scale

  • AWI (Automatic Weighing Instrument) conforming with OIML R61
    For example: Sacking system scale, Filling scale

  • Automatic Catchweighing Instrument conforming with OIML R51
    For example: Single component scale for filling and emptying scales, Multi-component scale, Static control scale for weight measurement

  • Discontinue Totalizing Automatic Weighing Instrument conforming with OIML R107
    For example: Emptying scale, Loading scale
