Do anyone have example of using the "IecVarAccess" library ? Did some testing but could not figure this out !
Want to read/write the "Symbol Configuration". If it works it's maybe possible to manipulte the published OPCUA variables in run-time (?).
Thanks,

To be confirmed by some admin, but to me, OPC UA server is in general configured by a config file at startup, so you would also have to control your OPC UA and correctly place the file in the PLC filesystem.

Yes it may be as you describe. But it would anyway be nice to work with the IecVarAccess library! Thanks.
