Hey, PushThese field is a value of ProdID field in feeder components like Basic Feeder. It is a dynamic component’s ProdID. By default the value is 111 and that works with any component you feed into simulation. Hope this helps.
If you use Basic Feeder with custom component it still works. If you use custom feeder component aswell (I believe that blue block?), you have to write some logic in python. Check Basic Feeder component for reference but basically it is done like this:
Add string property “ProdID” to creator component.
Create parts using python script and assign ProdID property to created parts.
I think the Pusher Conveyor checks for dynamic component’s ProdID property.
Regarding your last question. Yes, you can activate it using robot’s output signal but I am not sure what the easiest way is. If you know how to write python scripts then you can do it this way.
Hope this helps, if not let me know.
