SIWAREX WP231 is the first weighing module designed for SIMATIC S7-1200 integration via the Totally Integrated Automation (TIA) Portal engineering platform.
The ability to operate SIWAREX WP231 with or without SIMATIC PLCs offers additional flexibility and the Ethernet and RS485 interfaces with Modbus protocol enables integration 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.
Features- Uniform structure and universal communication through the integration in S7-1200
- Four digital inputs and outputs, one analog output, all inputs and outputs are controllable via the SIWAREX module or via SIMATIC S7-1200
- Operation also possible without SIMATIC CPU
- Easy commissioning via SIWATOOL or via HMI touch panel
- Extensive diagnostic functions
- Calibratable display
- Flexible adjustment for different requirements
- Theoretical adjustment without adjustment weights
- Modules can be exchanged without readjusting the scale
- Can be used for Ex-applications zone 2
