OPC UA module question

Does anyone know the maximum number of nodes that can read in any request?

I ask because I have a Siemens OPC connection that faults out frequently and we are trying to figure out why.

The max would vary from server to server.

There is probably a warning or error in your logs around the time of the faults that would help figure out why.

Thanks I also see this

any way to explain this code=15?

Privilege violation, I think. It’s from a legacy ControlLogix driver connection and not your Siemens OPC UA connection though, so entirely irrelevant.

your right, it doesnt pertain to the siemens at all just curious about it.
