Does anyone have a good example of a FIFO that captures time and date stamp when an event happens?? I'm looking for something like this for a ControlLogix Processor.

I just make up a UDT to contain my event record (Time/Date as a string, event type, tolerances, footage, run conditions, etc), and then make an array of them.
The array is what gets populated with a new record using the FFL instructions. I scan the .DN bit after every add, and use that to pop off the earliest record with FFU, and send that to the database.
In my case, I'm doing this to take a cross section of a continuous product over about a thousand feet.
