Is there any way to add the duration of events frames over a period? And Show in PI VISION?
One possible approach is you can output the duration of each of the eventframes to an attribute using the EventFrame(Duration) function. Then you could run a second analysis that sums up the event frame duration and outputs to an attribute which you can pull into PI Vision.
Hope this helps,
Could u explain how can i associate an attribute of EF to Element?
When you setup the Event frame generation analysis, you can have an output expression which will create an attribute associated with the element on which the EF gen analysis is configured:
Thank u so much!
u r very prestative!
I did, but this output expression. stay associate in EF.
I didn't found one place to sun this information in Element.
PI Vision supports event frame table. You can add event frame table to your display and add element or associated attributes accordingly so that i can display all the associated event frames related to the element over the display time range selected.
Reference : PI Vision - Event frame table
Note : External attributes cannot be added to event frame table from element. But you can use the existing attributes shown the screen shot 1.
