How to Tell which FC instance is triggering?

Hello,
Does anyone know of a way to tell which instance of a FC is enabled and trigger logic. The reason I askis because I use some FC's that are used in multiple places inthe program, andthe FCmay be triggerby any of the locations.
Currently I have to do a reference data displayof the FC and then go to all of the locations of the FC, then go online,then see we if the logic is activly triggering the FC's inputs.
The Processor is a 317 2DP

ANY IDEAS
Thanks In Advance
