The Siwarex WP231 is the first weighing module for the Simatic S7-1200 control system. The module is suitable for monitoring filling levels in silos and bins and for products being weighed on platform scales. It is intended for industries that require a high level of accuracy, such as food and beverage, pharmaceutical and chemical industries. The device is suitable for use in explosive atmospheres, Ethernet connections and an RS485 RTU interface with Modbus protocol enable it to be operated from a Modbus HMI panel without being connected to the Simatic S7-1200 control. — Siemens Industry Automation Division, Nuremberg, Germany
