Hello There!  
When I go to search for the factory io nodes, I can’t find all the nodes that I configured via global variables.  
My global variables in Codesys:  
OPC\_ESTEIRA: BOOL;  
OPC\_RUNNING: BOOL;  
OPC\_SENSOR: BOOL;

But when I go to look in FactoryIO, it doesn’t show me these variables!

OPC Client DA/UA

No items/nodes found on server ‘OPCUAServer@DESKTOP-8C95251 (UA)’ using filters: Start with: ‘OPC’ Contains: “”

Kind regards and thanks!

Can you try a tool like UaExpert or similar to connect to your OPC server and browse your nodes to see if the problem lies in the driver settings in Factory I/O?

Maybe your filter is wrong? Have you tried without the “Starts with” filter?

Hello, I’m having the same problem. When i log in to the OPC UA server using a test client, I can see my OPC tags coming from Beckhoff plc. I can change values of the OPC tags in the plc and on the server and see state change on other side. So OPC comms is ok. But when i connect the factory io driver to the OPC UA server and browse for available nodes, i can’t find any node. Even though i can see and manipulate the tags from the server and from the plc. Any ideas?
