OPC-UA Fault - not a known server type

Ignition

Hi,

I'm getting an error on the OPC-UA module.
What is the problem?

java.lang.Exception: OPC server connection is faulted. Type "com.inductiveautomation.OpcUaServerType" is not a known server type.

That looks like a side effect of a separate fault starting Ignition's native OPC UA server. Is the OPC module installed? And not faulted? Look for more wrapper log entries related to that.

Thanks for your reply. The OPC-UA module is installed.

And faulted.

You should contact support. Something about your java environment has changed.

(You are also using an unsupported version of Ignition. You should consider upgrading.)

I would use an external OPC-UA client to see if you can access it. If you do then you can eliminate that part and concentrate in how you are configuring Ignition.

The module is faulting during startup so I wouldn't expect the server or any client connections to be available.

Provide the wrapper logs or consider calling into support so they can take a look.
