TwinCAT software now supports S7 communication protocol

Beckhof now offers an add-on to the TwinCAT 3 automation software that enables easy and efficient communication with Siemens S7 controllers. This option provides tighter integration with other machines and equipment while simplifying implementation to reduce engineering time, effort and cost. The openness of PC-based control and the resulting range of connectivity options with other systems are among the fundamental advantages of Beckhoff’s TwinCAT automation software.

TwinCAT 3 offers many options for connecting TCP/IP-based third-party systems to the main control program: OPC UA, MQTT, HTTPS and Modbus are some important examples of the full range of supported communication protocols. The TwinCAT S7 Communication function (TF6620) now extends this broad spectrum to the S7 communication protocol.

This product implementation allows reading and writing of variables from an S7 PLC. The PLC application program takes care of this directly, either via dynamically parameterizable 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.
