TwinCAT 3 now also offers a function for the efficient connection of S7 controllers.
Beckhoff Automation has created an add-on for its TwinCAT 3 automation software - an add-on which the company's PC-based Control uses to communicate with S7 controllers from Siemens. More information is available at the digital Hanover Fair.
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 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.
