3.3 Application Range
SIWAREX FTC is the optimal solution wherever weighing technology requires high
speed and accuracy. Because of the high resolution (3 x 6000 d, legal-for-trade or
16 million parts internally), scales can be built to work accurately over broad areas.
SIWAREX FTC can be used for creating container scales, platform scales, force
measurement devices, belt scales, loss-in-weight scales and bulk flow
measurement devices.
3.4 Structure
SIWAREX FTC is a function module (FM) of the SIMATIC S7-300 and can be read
directly on the SIMATIC S7-300 or ET 200M bus. Installation / cabling efforts for
the 80 mm wide module is simplified with the profile rail assembly (snap-in
technology).
Connection with the load cells is done using 40-pin standard front terminal strips,
the power supply is through a 2-pin plug and the serial interface is through a 9-pin
D-type plug connector.
Operation of the SIWAREX FTC in SIMATIC guarantees complete integration of
weighing technology in the automation system.
3.5 Function
The primary task of the SIWAREX FTC is highly accurate measurement of the
current weight and exact determination of the material quantity.
There are different weighing or measurement procedures, for which the SIWAREX
FTC can be optimally configured by defining parameters.
The following operating modes can be defined:
- Non Automatic Weighing Instrument – in accordance with OIML R-76
Instrument
- Force measurement
- Belt scale
- Loss-in-weight scale
- Bulk flow measurement device
