Frequently Asked Questions

Application, load-cell compatibility, installation, calibration, performance, communication and ordering guidance for SIWAREX WP321 ST.

01

Which weighing applications suit the SIWAREX WP321 ST?

The single-channel module is intended for platform, hopper and similar scales using analog strain-gauge load cells in a SIMATIC ET 200SP station.

03

What load-cell connection must be verified?

Use four- or six-conductor full-bridge strain gauges within the documented 40–4100 Ω bridge range and 1–4 mV/V signal range. Preserve shield and sense wiring.

04

What installation limits apply to the module?

Install it on BaseUnit type A0. Observe −25 to +60 °C horizontally or −25 to +50 °C vertically and derate ambient temperature above 2000 m.

05

How should a replacement module be calibrated and commissioned?

Restore the scale parameters, perform zero and span adjustment with approved test loads, verify stable weight indication and save the final calibration data through the controller project or SIWATOOL V7.

06

What performance and service-interface values matter?

The published sampling rate is 600 Hz with 0.01% linearity error. The RS485 service interface supports up to 115.2 kbit/s over a shielded connection.
