Is there any limitation for the OPC UA Server with Operator Terminal Expert?

Product:

EcoStruxure Operator Terminal Expert v3.x , v4.x (EOTE)

Environment:

HMI Configuration Software in Windows

There is no strict limit; however, monitoring a large number of variables can impact HMI performance.

The recommendation from R&D is to keep OPC UA communication variables below 5,000 (this number was validated by R&D in previous tests).
