using PI OLEDB (or by other means) it is possible to store two values of the same tag at the same timestamp in the PI Server. E. g.:
Is there any global setting of the PI Server (or of PI SDK) which prevents the PI Server to store more than one value at a time?
An insert statement should fail, if the is already an value at the same time. Or the existing value shoult be replaced.
The second value (with _index = 2) in the example should be rejected from the PI Server or should replace the first value.
