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 (

ontroller).
The SIWAREX WP321 is calibrated at the factory. This allows for automatic calibration of the
scale without the need for calibration weights and replacement of modules without the need
for recalibrating the scale.
A PC for setting the parameters of the electronic weighing system can be connected via the
RS485 interface.
The SIWAREX WP321 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.
