Weighing module SIWAREX WP251
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.
