The weighing module SIWAREX WP251 is part of the SIMATIC S7-1200 Basic Controller family and seamlessly integrated into TIA-Portal.
SIWAREX WP251 controls dosing and batching tasks completely independent and fulfills the typical requirements of these processes, such as speed and accuracy.
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 / Touchpanel – thanks to the WP251 function block without any additional programming!
Additionally, SIWAREX WP251 is very flexible in its usability: Integrated in SIMATIC S7-1200 all advantages of the automation system can be used: customer and application specific requirements can be added and programmed in the SIMATIC CPU easily. This offers a free programmable and flexible weighing solution by using SIMATIC standard components. Operated in stand-alone mode all parameters and functions can be accessed and edited via the on board Modbus RTU or Modbus TCP/IP interfaces. In this case a PC or a Modbus-compatible user interface can be directly connected and used for operation.
With the trace function it is possible to optimize the scale. The saved values and status information can be illustrated and analyzed with SIWATOOL V7 and Microsoft Excel.
