micrologix 1000
(OP)
I have an application where I need to track parts entering an exiting a machine. There is a photoeye at the entrance and a photoeye at the exit. Once a part enters the machine it has a certain time to exit the machine or the machine needs to be shut off. The problem that I am having is that there can be multiple parts inside the machine at once which will require multiple timers. Does anybody have any advise on how to keep track of this in RSLogix? Any help will be appreciated.

You have to shift the last accumulated value first, assuming a 3 part capacity timer[1] (process) would shift into timer[2], then timer[0] would shift into timer[1] and so on to suit.
Once the shift is complete you can then look at the accumulated values an see if any are over limit.
If you have ST programming capibility the check routine could index through the array and return 1 if any value is over limit.
Be sure the shift is triggered from a oneshot, and you reset timer[0].
