Diagnostic Parameters and OPC

I would like to bring some controller diagnostic parameters into my Pi system so I can use email to notify maintenance personnel of controller issues. I was looking to use the OInteg and OLInteg parameters to create the notifications. I used an OPC client to navigate the diagnostic parameter and noticed the top level, Restart and Redundancy parameters were exposed but not Communication. Is there a way to get the communications diagnostic parameters with OPC?

I have DeltaV 13.3.1
