SIWAREX WP241 Weighing Module

Brand: Siemens AG
Does not ship to OH, United States
SIWAREX WP241 weighing module can easily be integrated into SIMATIC S7-1200 via the TIA Portal but can also be operated without a SIMATIC CPU. 

It has been designed for monitoring belt scale and weigh belt applications.

SIWAREX WP241 can be connected directly to a Modbus HMI (Human-Machine Interface) panel through Ethernet connections or an RS485 RTU Interface. 

The standard functions for belt scale control, such as flow rate, belt speed and belt loading can be adapted and extended as required. 

The simulation mode allows users to test functions like belt speed, belt loading, flow rate and many others, without a moving conveyor belt. 

For commissioning and operation, the TIA Portal project “ready for use” for operator panels is available. 

In addition, SIWAREX WP241 can be used in hazardous areas zone 2/22.
Features
  • Uniform structure and universal communication through the integration in S7-1200
  • Standalone operation mode without SIMATIC CPU possible
  • Modbus TCP/IP & Modbus RTU
  • 6 totalizers (individual resettable)
  • Pulse signal for remote totalizer
  • Simulation mode for belt load and/or belt speed
  • Trace recorder
  • Recovery point for easy rebuild of all parameters
  • Automatic zero tracking function
  • Easy commissioning via SIWATOOL and PC or via HMI touch panel
  • Extensive diagnostic functions
  • Flexible adaption to different requirements
  • Various calibration options
  • Can be used in hazardous applications ATEX zone 2
