I tried to connect an Arburg press which has an OPC Server onboard.
I configured it in Ignition and the connection is fine
If I load the tags in the designer via the opc browser, both are red and in config error
they used to work at a first config, then I close the designer and reopen it and I got this error. Even by recreating the the connection I have the same error
any idea on how to solve it?
