I have two questions....
I have tried with various guesses. And tried to connect to the DA server without success. All runs on the same PC. From the picture I would guess the address is 004 or 0301.A026.
for a try I would select Tcp blockdriver and give the Ip address in the opc da configuration
Think on using OPCUA the modern way of communication - encryption is possible and
this OPCDA configuration nightmare is gone.
You get an update on Windows and never know if OPC DA is still working.
There are so many OPCUA clients available.
Check if your client have it in.
It's solved now. For question 1, the answer is YES. Regarding question 2, I edited C:\ProgramData\CodeSys\CodeSysControlWinV3x64\XXXXXX\CodeSysControl.cfg ... there is a setting Node which I assigned a name to. Thus I could configure different names to the virtual PLCs I used. The names I used in "PLC name ord address" - refer to previous pictures.
