Only send item if over certain age (time spent on conveyor)

Hi all,

I have items (boxes) entering a conveyor, as they enter the conveyor their creation age should be set (0 or time()). These boxes should move along the conveyor and once they reach a photoeye at the end their time on the conveyor/age should be checked, if they are older than 60 seconds they can be released otherwise the conveyor must stop until this box is >= 60 seconds age then the conveyor can continue, this should apply for each box. I've tried stuff like putting a photoeye at the end and checking the age something like "if time() - creationAge < 60 set conveyorspeed 0 else set conveyorspeed 200". Obviously that doesn't work, I've played around quite a bit and if I get it working it only works for the first box and messes up on all the other boxes.

Any help would be appreciated.

@Grant S2

Here is an example of how you could do this:

sendifold_PS.fsm

When the item arrives at the DP it checks how long it has been on the conveyor. If that time is less the 60 sec, the conveyor stops completely and then has a delay for the time left until 60 seconds, then everything resumes.

Let me know if you have any questions!
