Connecting to Node opc-ua

Ignition
1

Hello,
I’ve some problem while trying to connect Ignition as a client to a Node-OPCUA ( node-opcua.github.io/ ) server . Ignition connects correctly to the server (“simple server” demo) but I’m unable to access the exposed variables with the Quick Client. I’ve tested the same server with another opc ua client and works correctly, I can access the variables.

You can’t see them while browsing? Or you can’t read them?

Can you capture the traffic between Ignition’s client and the node server with Wireshark and post it here or email it to me?

The server simply isn’t returning any nodes other than what you see in response to browsing the Server node. Are the variables you’re expecting to see being added with a non-hierarchical reference by chance?

You know, I just looked at the node-opcua server example and it looks like it adds the folder and nodes to the root of the address space. Ignition’s OPC-UA client doesn’t browse from root, it browses from the Objects folder.

If you modify the example to add things starting from the Objects folder you’ll probably see the nodes you’re looking for.

Yes, now it works! Thanks
