Why does a conveyor still wait for a missed product ?

In the attached model (use-transport-at-exit-transfer.fsm), the operator misses to pick the 1st product on the conveyor because he was too far away.

After that, he never tries to pick any other product. The input port of the entry transfer stays red, as if it was still waiting for the 1st cancelled transport to be completed.

My assumption is that once the 1st box passes the end of the exit transfer, the input port of the entry transfer should turn back to green to accept a new product. Why is not working this way by default ? Did I miss a step ?

Looks like there may be a bug with connecting to another Conveyor's entry transfer when the task sequence can be aborted. If you place a dummy queue at the base of the 2nd conveyor and instead connect the exit transfer to the queue and then connect the queue to the entry transfer of the 2nd conveyor, then it works just fine.

I'm not sure if this option will work for your situation. All you need to do is check the Stop Item at Transfer End in the Exit Transfer Properties of ExitTransfer2. This will allow the operator to get to the flowitem because the flowitem will stop at the end of the exit transfer area.

Thanks Jeff, but I actually unchecked the option "Stop Item at Transfer End" on purpose. The goal is that when the operator is busy somewhere else or too far away, he won't have time to pick the product and so the product continues on the conveyor.
