Product
Overview
3.4 Function
The primary task of the SIWAREX MS consists of measuring the actual weight
value. Integration into SIMATIC enables the processing of weight values directly in
the PLC.
SIWAREX MS is already being adjusted in house. This means that the scale can
be adjusted to theoretical settings without using any adjustment weights and
modules can be exchanged without readjusting the scale.
The SIWAREX MS has two serial interfaces. A TTY interface is used for
connecting remote digital displays. A PC can be connected to the RS 232 interface
to set up the scale using the SIWATOOL MS.
The SIWAREX MS weighing module can be used in zone 2 explosion hazard
areas. An optional Ex interface on SIWAREX IS or SIWAREX Pi gives load cells an
intrinsically safe power supply for applications in zone 1.
3.5 System Integration in SIMATIC S7-200
SIWAREX MS is a component of SIMATIC S7-200. This gives you complete
freedom for configuration of the automation solution - including the weighing
application. The optimum solution can be created for small, medium and large
systems by selectively combining the SIMATIC components. Customer specific or
branch specific solutions can be developed quickly and easily using the
configuration package and the “ready to use” application “Getting started”.
3.6 Scale Adjustment with SIWATOOL MS
For adjustment of the scale, there is a special program - SIWATOOL MS for
Windows operating systems (Windows XP and higher).
The program allows the weighing specialist to commission the scale without having
to understand automation technology. During servicing, you can analyze the
processes in the scale and test them with the aid of a PC independently of the
automation system. Reading the diagnostic buffer from the SIWAREX MS is very
helpful in analyzing events.
