4.1 Functions
The primary task of the electronic weighing system is the measurement and registration of
the current weight value. The integration in SIMATIC gives you the option to process the
weight value directly in the PLC (ProgrammabelLogic Controller).
The SIWAREX WP231 is calibrated at the factory. This allows for automatic calibration of the
scales without the need for calibration weights and replacement of modules without the need
for recalibrating the scales.
The Ethernet interface can be used to connect a PC for parameter assignment of the
electronic weighing system or for connection to any automation system (Modbus TCP/IP).
The SIWAREX WP231 electronic weighing system can also be used in potentially explosive
atmospheres (Zone 2). The load cells are supplied intrinsically safe in Zone 1 applications
when you use the optional Ex interface SIWAREX IS.

The SIWAREX WP231 can also be used in standalone mode independent of the automation
system. There are many configuration options in this case.
The user can select the enclosure as well as the Operator Panel. But the Operator Panel
must support Modbus RTU or TCP/IP. This means you can implement your own operating
philosophy.
The SIWAREX WP231 can be controlled remotely without its own Operator Panel on site.
One Operator Panel can be used for several scales. The configuration options are almost
unlimited in this case.
