While making some tests with OPC UA on a wago PFC100 I found that my function block methods and properties where not available from the opc client (UAexpert)
This led me to having a look at the PLCopen and OPC foundation "OPC UA Information model for IEC61131-3".
I can not find any information regarding IEC61131-3 methods.
It seems obvious that function block methods should be mapped to OPC UA methods, so that when exposing ie. a motor object(FB) with start() and stop() methods, these methods are available from the opc client.
Am I missing something?
