TimeSource - property of the PmVar object

Description:
Time of value origin in the value source by source time (this is not the time when the value got into the PROMOTIC application).
Syntax:
Date TimeSource
Calling:
d = oData.Item(2).TimeSource
Note:
Property access for read only.

The value of this property can be also obtained in the "PmaRoot" item of the INFO system (when looking into the object with this property).

 
It is possible that this value is filled in by some communications (so far only the PmOpcUaClient communication driver - see the "Time reading type" configurator), when the value is read from the communication together with the corresponding timestamp (and possibly also with the quality).
