Re: Possible to read and write S20 Ethercat bus coupler AI-4-I using OPCUA in CtrlX?
the current resolving of the Ecat-DatalayerKnots is limited yet. The implementation does not cover yet the subnotes under instances. Not nice but I case you can live with a workaround inside the PLC. you could make the values available als RTData read and provided as new RT-Variable by the PLC. ( Time delay of 1cycle expected/acceptable?).
1.Add the RT-Infos of the AI-channels to the PLC. 2. Provide new vars als RT Vars into the Datalayer (using the pragma declare) 3. copying read value to new var.
Unfortunately I can not provide a releasedate for the expected resolving.
