It would be nice to have the option to select either starttime or endtime of the eventframe as the timestamp for the value that will be written a PI tag using the Outputs at close feature in Event Frames. Currently, it will only write the value with a timestamp of the endtime of the event frame.
Use case:
I have an event frame and I would like to see the average of an attribute value for that duration of that time frame on PI Vision. The expectation is to see a horizontal line indicating the average value throughout the duration of the event frame.
As of now, the average value is written to the underlying PI Point with the timestamp at the end time of the event frame using the Outputs at close feature in Event Frames.
This leads to a sloping trend when you try to visualize the resultant average values. i.e. the trend links the previous average value (calculated from the end of the previous event frame) to the latest event frame output average value.
With the requested option available and combined with the step parameter in the PI tag, we will be able to visualize a straight horizontal line for the average value of the tag for the duration of the event frame for that particular duration.
