SIWAREX WP251 controls dosing and batching tasks completely independent while fulfilling the typical requirements of these processes, such as speed and accuracy. As part of the SIMATIC S7-1200 basic controller family the module is integrated seamlessly into TIA-Portal. Optionally it also can be used without SIMATIC CPU in stand-alone mode. Operation and commissioning of the scale are quick and easy: due to 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 – thanks to the SIWAREX WP251 function block without any additional programming! 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.
