How to Avoid FTV SE HMI Error Messages in Diagnostic Viewer when PLC Communication Lost
PLC lost is communication with HMI server. The 1000 of error will generate in diagnostics viewer in client systems. How to avoid these errors?

We Have FTV SE distributed redundancy server client system, in the system having 9 separate data servers which are connected to HMI server. If the data server or PLC communication lost, the 1000 of error will generated in client systems in diagnostics viewer. So I need to avoid those error when this data server or PLC disconnected.

Because of those errors, the HMI tag updation time will increase and client system started running very slow.

Here Error samples for more information.

On the panelview hmi software (rsview) there is an option on the diagnostics tree to display errors, information, warnings, etc. If you disable those, you shouldn't get then displayed. You can also limit the number of such messages there.
