Transport option

I have a model set up as follows:

Source -> Queue1 -> Processor(x16) -> Queue2 -> Sink.

I have to check the "use transport" tick from Queue1 to every one of the processors. However, when this option is "ON" the processors only work once, and then they seem to be blocked. I mean, there is no Flow from the Queue1 to them after they have been used once. When the "use transport" in Queue1 is OFF, the whole thing runs as it should. Is there any way for me to make it work with the "use transport" tick as I want?

Thank you in advance for your reply.

@Brayan Leonardo Gil Guevara Would you be able to send us a sample model so we can see what's happening? Thanks.

Hi @Brayan Leonardo Gil Guevara,

For your operators to carry items from Queue4 to the 16 processors, you only need to check the Use Transport box on Queue4.

The Use Transport option applies to downstream travel only. You do not need to check that box for any of the downstream objects you want transported to (unless they are to use transport to their own downstream objects).

By checking the Use Transport boxes on the processors, you are telling the processors to only send to Queue13 with a transport. However, if a processor does not have a center port connection to an operator or other transporting object, then the item in that processor can't leave because the processor can't get anything to transport the box away. Thus the item becomes stuck in the processor, the processor can't accept new items, and the model eventually stops with all processors blocked.

So, the solution is to NOT check the box on the processors for Use Transport unless you want the operators to also carry from the processors to Queue13, and you connect them up to do so.
