Hello,

I have a S7-400 connected to a TP1200 Comfort HMI by MPI and would like to access HMI tags via OPC UA connection. There is a WAGO PFC100 PLC running a OPC UA server in my network environment and I would like to connect the TP1200 Comfort to this network and have access to the HMI tags.

Is that possible?

Hi RTasso,
