This course explains the steps to create PLC tags and enable OPCUA communication between the Simumatik Gateway and Automation Studio 4.8, including the programs and I/O signals.

Automation Studio version 4.8 is used in this tutorial.

In this example the data that will be transferred is:

• ‘inputs’: A PLC input byte (inputs.0…7) addressed to the variables.

• ‘outputs’: A PLC output byte (outputs.0…7) addressed to the variables.
