3 Product Overview
3.1 General Information
SIWAREX FTA (Flexible Technology, Automatic Weighing Instrument) is a
versatile and flexible weighing module which can be utilised wherever a scale
should fulfil its tasks automatically. 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. The module can
also be used without SIMATIC, as a stand-alone module however.
The scale functionality of the SIWAREX FTA includes the non-automatic scale
(Non automatic weighing instrument conforming with OIML R-76), the automatic
scale for balancing (Automatic gravimetric filling Instrument conforming with OIML
R-61), the automatic scale for catch weighing (Automatic catch weighing
instrument conforming with OIML R-51) and the automatic scale for discontinuous
totalising (Discontinuous totalising automatic weighing instrument conforming with
OIML R-107)
