How to start PLC Method by DataLayer or OPC UA

Hi,

Is it possible to start PLC Function, Method, FB or somthing different by DataLayer or OPC UA and wait for response?

In IndraWorks I used SymbolConfiguration option "Support calls to Function, FB..."

But I can't find it in PLC Engineering

What is the best way to achieve this?

Best regards,
Andrey

One easy way would be to define an interface like PLCopen. Add start and finish Booleans and an input and output variable to the Data Layer.
