SIWAREX WP251 controls dosing and batching tasks completely independently while fulfilling the typical requirements of these processes, such as speed and accuracy. 

As part of the SIMATIC S7-1200 basic controller family, the WP251 can be integrated seamlessly into the TIA Portal.

The SIWAREX WP251 weighing module can be used with SIMATIC S7-1200 or without a SIMATIC CPU in stand-alone mode. 

Operation and commissioning of the scale are quick and easy with the free software example application "Ready-for-use SIWAREX WP251”. 

The commissioning, calibration and operation of the scale can be done completely via the CPU or Touchpanel – the SIWAREX WP251 function block doesn't require any additional programming! In combination with a SIMATIC S7-1200 basic controller, all customer and application specific requirements can be easily met. 

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. 

A PC or any Modbus-compatible device can be directly connected and used for operation. 

In addition, 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.
