Issue:
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
Resolution:
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).
