SIWAREX WP251 is a very compact weighing module for dosing and batching tasks. The module can be installed seamlessly with the SIMATIC S7-1200 or operate as a stand-alone unit.
As part of the SIMATIC S7-1200 basic controller family the module integrates seamlessly into TIA-Portal or in stand-alone mode without a SIMATIC CPU.
Diverse options are available for commissioning. The SIWAREX WP251 function block enables full access to all parameters of the SIWAREX WP251 and the downloadable example application "ready-for-use" provides calibration and operation options for the scale - without any additional programming
The integration into TIA-Portal allows an activation of user interfaces and an upload to all available SIMATIC operator panels. In combination with a SIMATIC S7-1200 basic controller, all customer and application specific requirements can be realized easily.
In the stand-alone mode all parameters and functions can be accessed and edited via the on board Modbus RTU or Modbus TCP/IP interface. In this case a PC or any Modbus-compatible device can be directly connected and used for operation.
Beside that the SIWAREX WP251 offers a trace function. All traced process values and status information of the scale can be illustrated and analyzed with SIWATOOL V7 and, if required, edited in spreadsheets.
