conveyor control

conveyor controle test.fsm If product is stuck on the priority conveyor, you want the product to be transferred to an empty conveyor. I tried using photoeye to open/close the input port of the conveyor, but it didn't work. I need help.

Thanks in advance.

I met the same question before, i think if you decide where item go first ,it may still get stuck on the other way or be empty when using conveyor system.Pull strategy may be better.Using Processor with shape changed instead of conveyor piece is another choice.

There are many ways to do this and it depends how sophisticated and exact you want it to be.

You can get some way by simply routing based on the state of the photoeye with an expression like this :

current.pe.stats.state(PE_STATE_PROFILE).value==PE_STATE_BLOCKED

where the DP has a pointer label called 'pe' which is pointing the the photoeye (set it using the sampler).

Anything more sophisticated I would probably put into a process flow for easy tracking of events and counters and control of the flowitems.
