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 100, 120 or 600Hz 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 SIMATIC Step7 V5 as well as in TIA Portal.

SIWAREX WP231 is the first weighing module for SIMATIC S7-1200 and through this is programmable via the Totally Integrated Automation (TIA) Portal engineering platform.

The ability to operate SIWAREX WP231 with or without SIMATIC PLCs offers you the flexibility you need.

The Ethernet and RS485 interfaces with Modbus protocol enables you to integrate the weighing module into different control systems. 
SIWAREX WP231 offers four digital inputs and outputs and one analog output. All inputs and outputs are controllable via the SIWAREX module or via SIMATIC S7-1200.

The high resolution of one million parts and the measuring rate of 10ms guarantee a reliable weighing in all of your applications.

The module also offers extensive diagnostic functions for commissioning and operation like trace of weight or monitoring of limit values

The commissioning is either possible via the new SIWATOOL or directly via a connected HMI touch panel.

Thanks to the automatic adjustment the application is ready-to-use in only a few minutes.

The SIWAREX WP231 can be used in following applications:

• Non-automatic scale according to OIML76

• Level monitoring of silos and bunkers

• Weighing in hoppers and platform scales

• Suitable in hazardous application (with SIWAREX Ex-Interface IS)

SIWAREX WP521 ST and WP522 ST are technology modules for the SIMATIC S7-1500 advanced controller family and are optimally prepared for gravimetric level measurement of silos and hoppers as well as for platform scales. Beside that the weighing modules can also be used for weighing applications in hazardous locations (with Ex-interface SIWAREX IS).
The new technology module is available in two variants: SIWAREX WP521 ST as single channel option for the set-up of one scale and SIWAREX WP522 ST as two-channel option for the set-up of two independent scales. 
Integrated in SIMATIC S7-1500 all advantages of the automation system can be used. The free “ready-for-use“ application helps to create fast and easily customer and application specific solutions. Besides that, the service software SIWATOOL V7 enables a quick and user-friendly Different interfaces and connection possibilities are available on board:

SIMATIC S7-1500 system bus, Modbus TCP/IP (Ethernet), Modbus RTU (RS485), four digital outputs and three digital inputs. The integrated monitoring function of the load cells impedance as well as the process and diagnosis alarm functions optimize the plant security resp. plant availability
