Friends, hello everyone. My current project requires communication between OPC UA and a third-party HMI. The CPU I’m using is X20CP3684. How can I export the OPC UA tags in the project? I need to import all the OPC UA tags from everywhere into the third-party HMI to enable communication between the third-party HMI and X20CP3684 using OPC UA tags. Please tell me how to do it, friends.
Hi @BR950029 ,
please login on our website and study the training module TM980 - OPC UA basics and use
In the training module you see step by step what you need to communicate via OPC UA with your hmi.

After compiling the project, you will find in the Temp folder under your configuration the OpcUaMap/OpcUaMap.uar file. You have to change the extension to .xml in order to get the nodeset file of our OPC UA server. I would use this XML file to create a script to generate a file in the format required for your third-party HMI.

Thank you for your reply. I found the file following your method, but I still couldn’t import the tags of the third-party HMI. I’ll try other methods next. Thank you again!
The reason for the inability to import XML has been identified. Here, I’d like to share it with you all. In the OPC UA settings, change the information model from 1.0 to 2.0.
