I am evaluating Ignition 8 and am trying to connect to a CODESYS SoftPLC configured as an OPC-UA server. I actually have two PLCs : one locally on my laptop (which also hosts Ignition), and the other one on a Raspberry Pi. In both cases, I encounter the exact same problem. I know the OPC-UA server works, as I was able to connect with a separate client (no certificate, no user/password).
When I try connecting to the OPC-UA server from Ignition’s configuration, it seems to work fine. I am able to get to the last step, which shows “opc.tcp://127.0.0.1:4840” as the endpoint, along with Security Policy : none and Security Mode : none. I hit finish, and the connection comes out as “Faulted”.
The connection log shows this :
UaException: status=Bad_ConfigurationError, message=no matching endpoints found
Azul Systems, Inc. 11.0.3
I have seen in the migration notes that the server’s certificate needs to be marked as trusted. I have generated a certificate, and marked it as trusted. The problem remains the same.
I must be missing something very simple here, but I have been unable to find what it is.
Thanks in advance for your help.
