Hi @leonberger-m, you are using the ctrlX OPC UA Client App, right? (from the initial question I was not sure if you are using the Client or the Pub/Sub App) I think, the problem is, that you are trying to access a complex data type with the OPC UA Client. I took a look into the documentation of the OPC UA Client App and found a list of the supported data types (link to the docu). I think this might not match with your complex data type. Best regards, Nick

Thanks for the question. I forwarded the question to the dev team. I will come back to you here if I got an update.

Hi Aron, there was a known issue with ctrlX OPC UA Client App V1.18. Subscriptions to OPC UA Client nodes did fail after a reconnect to the OPC UA Server was done by the client. So I think you can reproduce this error, if you disconnect and connect the OPC UA Server via the web-ui. To solve this, you would need to update to V1.20 of the ctrlX OPC UA Client App. This issue is solved here. Regards, Nick

Yes this is true. In this example "boschrexroth" is the user name and the password of the ctrlX CORE with the IP-Address 192.168.1.2.

Hi Chris, The error "BadNodeIdUnknown" indicates, that a path to a Data Layer variable in your configuration can't be reached. Please check if both, the "Published Variable NodeId" from your writer can be found and also the "TargetVariableNodeId" from your reader can be found. A detailed manual on the ctrlX OPC UA Pub/Sub App can be found here. The docu also includes a sample on how to setup a configuration, maybe this could also help you. Best regards, Nick
