PC-based control simplifies integration of S7 controllers – enables easy and efficient communication.
March 2021 – The openness of PC-based control and the resulting array of connectivity options with other systems number among the fundamental advantages of TwinCAT automation software from Beckhoff. A new add-on now also enables easy and efficient communication with Siemens S7 controllers.
TwinCAT 3 offers numerous options for connecting TCP/IP-based third party systems to the main control program: OPC UA, MQTT, HTTPS and Modbus are only a few prominent examples of an entire range of communication protocols. The TwinCAT S7 Communication (TF6620) function now expands this broad spectrum to include the S7 communication protocol.
This product implementation enables reading and writing of variables from an S7 controller. The PLC application program carries this out directly – either via dynamically parameterisable PLC function blocks or via easily configurable I/O mapping. No additional hardware is required and the local TCP/IP network serves as the transport medium.
Beckhoff implements open automation systems using PC-based control technology. The product spectrum comprises these main areas: Industrial PCs, I/O and fieldbus components, drive technology and automation software. Product series are available for all areas, which can be used as individual components or function collectively as a complete, harmonised control system. Our New Automation Technology philosophy stands for universal and open control and automation solutions that are used worldwide in a wide variety of applications ranging from CNC machine tools to intelligent building automation systems.
