Line working only if another one works

Hello

I'm trying to model the following production situation :

Line1 (Source1-Processor1-Sink1) has a long process time and Line2 (Source2-Processor2-Sink2) has a faster process time. And Line2 should only work when Processor1 is processing.

I searched for different solutions but i couldn't find anything

Any help would awesome

Thanks

Hello Marius,

I've attached an example of one way you could handle this.

I used a process flow attached to Processor2 which performs the following steps in a loop :

stop Processor2
wait until Processor1 contains an item
resume Processor2
wait until Processor1 is empty

If you want Processor2 to finish its current process before stopping once Processor1 is empty, you could stop and resume its input instead of stopping the object.

Hopefully this is what you were looking for.

If you're referring to this from my answer :

If you want Processor2 to finish its current process before stopping once Processor1 is empty, you could stop and resume its input instead of stopping the object.

You can find the options to stop and resume an object's input in the custom code activity under Control / Close and Open Ports.

If that's not what you meant, could you try to clarify?
