i’m facing troubles with tag historian. I want to use the deadband functionality that should register a change any time the value moves +/- the specified amount from the last stored value (in discrete mode).
Instead it’s register at any 10 second (my scanclass) even if the value has not changed.
What i’m doing wrong? Or maybe my expecations are wrong, so maybe somebody please can give an description of how deadband field works?
I tryed in many differend way but the result is always the same: the deadband field is ignored and the value is stored with frequency defined in scanclass.
Thanks for your kind feedback.
