I have an RFID device that has an OPC-UA server. I tried to connect to the device's OPC server through my ignition server and it was successful, and I am able to see the tags coming from that RFID reader. Then I tried to add the same RFID reader in my devices using TCP-IP and it connected successfully, I can see the device inside my Ignition OPC server in quick client, but when I open the device, I don't see the tags.
There's nothing to see with the TCP/IP driver. The only meaningful tag it has is the Message tag and it's only meant to be used with simple barcode scanner type devices that just emit plain ASCII strings over TCP to whatever is connected.
So, the correct way to do it is to just connect the OPC server of the RFID device to my ignition? I thought it would be similar to connecting a PLC through TCP/IP and be able to see the tags in my Ignition OPCUA server.
If it has an OPC server and doesn’t speak some other protocol we have a driver for then yes, that’s the correct way.
