Hello! I imported data points from the PLC using Importer S7+ Configurator . After a while, unreliable data began to arrive (values in the data points change but they do not correspond to the value in the PLC). The removal and addition of one DPs from DPTs.
The project of the PLC for this time has not changed. General properties were changed, points were added to the archives. Also during this time, the controller was turned off and turned on. What could be the reason for this situation?
Unreliable values between WinCC OA 3.15 and PLC S7-1200

How long after importing the datapoints start the unreliable data?
What happened in the time between the import and the start of the unreliable data?
How many values are read at which interval from the PLC?
Are there error messages written by the driver in the log related to the affected PLC?
