Connecting VTScada Lite OPCUA client to B&R PLC

posted May 26 '22 at 1:25 pm

Hello
I am trialling VT Scada and trying to connect to a B&R PLC running an OPC UA server.
I am able to set everything up but get no data back on the tags. Is this a certification thing?
Has anyone else successfully set up VT Scada with a B&R PLC?
Thanks
Simon

I haven't used a B & R PLC, but have used the OPC UA Client with many other servers.

Presumably you've been able to use the OPC UA Address Assist picker to locate tags so basic connection and tag browsing is working, so it's not likely that the x.509 certs are the issue.

Try drawing the driver instance Comms Stats button on a page to see what's being reported.

There's also the driver instance Diagnostics tab that has other info about the connection.
