2BPRODUCT OVERVIEW
3 Product overview
3.1 General information
SIWAREX U is a versatile and flexible weighing module, which can be used
wherever static scales are to be used in the SIMATIC S7 automation system.
The function module (FM) SIWAREX U takes full advantage of all the features of
the modern automation system, including the integrated communication, the
diagnostic system and the configuration tools.
SIWAREX U is not designed for legal-for-trade within the meaning of OIML-R76.
Customer benefits:

o Uniform design technology and consistent communication via the use in
SIMATIC S7
o Uniform configuration with SIMATC Manager
o Use in the peripheral system concept in ET 200M (PROFIBUS, PROFINET)
o Measurement of weight or force with high resolution of 16 bits
o High accuracy 0.05 %
o High measurement rate of 50 Hz
o Monitoring of limit values
o Flexible adaptation to different requirements with SIMATIC control
o Simple setting of the scale with the program SIWATOOL U via the RS 232 port
o Theoretical adjustment possible without adjustment weights
o Replacement of the module possible without a new adjustment of the scale
o Use in Ex-zone 2 / ATEX approval.
