OPC UA Server Limitations

OPC UA Server Limitations


Are there any known details for the limits on the amount of variables that can be used in a single instance of the process gateway running OPC UA server?

The context being, we're using Zenon to gather the process data from several different smart devices over MMS (IEC61850), then serving that collected data over OPC UA for a third party to connect to. Can 50,000 Zenon variables be broadcast over OPC UA without overwhelming the CPU on modern hardware?

Any insights on the resource limitations of the underlying Zenon OPC UA server implementation is much appreciated.
