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?
Solved! Go to Solution.
With the RM22.03 we have FBs (CXA_OpcUAClient) that can start methodes at our servers (like XM, MLC, ...)
But our ctrlX CORE OPCserver doesn't support methodes within the PLC (Symbol-Configuration). This will come end of this year.
And what about DataLayer, is it possible to start PLC method from C++?
I'm working on C++ app and want to process some task on the PLC side and wait for result of this task. To do this I need a way to run Method or Function in the PLC.
