The weighing electronic SIWAREX WP321 is a technology module for the distributed I/O system SIMATIC ET 200SP.
Due to the diversity and the flexibility of the SIMATIC manager and TIA Portal, it is possible to realize best solutions for small and medium automation systems. SIWAREX WP321 covers typical tasks of non-automatic scales: Both level measurement in silos and bunkers and platform scales can be seamlessly integrated in the automation environment.
The internal update rate of 10ms allows a fast and accurate force measurement, too. Scales in hazardous areas (if so with Ex-interface SIWAREX IS) can also be realized. The configuration package and the “ready for use” sample application offers a very fast development and implementation of customer- and industry specific solutions.
SIWAREX WP321 can be integrated and used in Step7 Classic as well as in TIA Portal
