3.3 Range of Application
SIWAREX FTA is the optimal solution wherever weighing technology requires high
speed and precision. Because of the high resolution (3 x 6000 d, calibratable),
scales can be built to work precisely over broad areas. Calibratable weighing
systems, whether a filling system, unloading station, bagging operation,
rotopacker, mixer or control stations can be constructed with the SIWAREX FTA.
Typical fields of application are e.g.:
o
Liquid filling
o
Bagging in a packaging system
o
Weighing catch levels as well as level decrease weighing and fill weighing
o
Catch level testing
o
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).
Connecting load cells, power supply and the serial interface is all done through the
40 pin standard front connector.
Operation of the SIWAREX FTA in SIMATIC guarantees complete integration of
weighing technology in the automation system.
In certain cases, the module can also be applied without the SIMATIC environment
in so-called stand-alone operation. The module then works as a compact module
that e.g. is connected to a PC.
