Pull rule

I have the following setup:

Queue (unlimited size) > combiner > seperator > Queue (200 max)

I'd like to add coding to the combiner so it does not pull parts from the queue if the second queue is full (i.e., contains 200 parts).

Any help would be greatly appreciated!

I usually find opening and closing ports is the easiest way to control this type of situation.

If you can link Queue 2 to the combiner then you can use the triggers on queue 2 to open and close the ports of the combiner depending on the content of queue 2.

Thanks for your quick reply!

I guess it'll be a case of using the "OnEntry" trigger on the second queue that looks at the current number of parts in it. Will this be an nObjects type code?

I'm not sure what you mean by nObjects, but on the onentrytrigger the code would look something like:

if( content( current ) >199 ) closeinput( centerobject( current, 1) );

and on the exit trigger

if( content( current ) <190 ) openinput( centerobject( current, 1) );

(I choose 190 to prevent jittering)

Thanks for your help, guys - seems to be working well now
