NEW WEIGHING MODULE ADDED TO SIMATIC S7-1200 CONTROL OFFERING

Easy to install measuring system delivers flexibility and accuracy for weighing applications

Siwarex WP231 is the first weighing module for the S7-1200 control and is suitable for monitoring filling levels in silos and bins and for use with goods being weighed on platform scales.

Joanne Banks from Siemens Industry comments: “This new product innovation is intended for industries requiring a high level of measurement accuracy, such as the food and beverage, pharmaceutical and chemical industries. In addition, it is also suitable for use in explosive atmospheres and has been designed to enable plants to increase operational efficiency across their processes.”

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.

The new Siwarex WP231 weighing module can be fully integrated into the SIMATIC S7-1200 control, and its parameters can be quickly and easily set via the TIA Portal engineering platform. The module has four digital inputs and outputs and one analog output. The Siwarex WP231 can be connected to various systems and operator panels via an Ethernet or RS485 interface with Modbus protocol and can be operated independently from the SIMATIC S7-1200, providing ‘stand-alone capability’. This ensures the module can be used in various applications. It can also be operated directly from a Modbus HMI panel in the event of failure of the control unit.

Whether operating in stand-alone mode or in combination with the SIMATIC S7-1200, the Siwarex WP231 offers a wide range of settings for parameters and alarm management, helping to enhance process efficiency. Users can define specific limit values and different parameters for the various individual outputs. Additional diagnostic functions, such as the documenting of weight and various process parameter readings (Trace), support greater transparency and facilitate the commissioning and maintenance of the module.

Due to its high resolution – one million parts – and a measurement cycle of 10 milliseconds, the Siwarex WP231 is able to measure with a high degree of accuracy. Clear menus ensure the weighing module is easy to operate, whether in conjunction with the SIMATIC S7-1200 or via a directly connected HMI panel. Its automatic set-up function also ensures that the measuring system is ready to use within only a few minutes.  For more information, visit www.industry.siemens.co.uk.
