Transmitting items

Hello,

I have a problem with transmitting items from a que to another proces. that;s not the difficult part but there are some strings attached.

I have 2 sources from each source the items go to a seperate que the que has a max content of 10. after the que the 2 different items are send to 2 different processors, one for item 1 and one for item 2. because there are more items of item type 1 I want to send some items to processor 2. But there are some conditions, the que from source 2 has to be empty and if the processor can proces 10 items at the same time it has a restriction when les then 5 items are occupied the processor can take some items from que 1 if there are more occupied it can't take items from que1.

source 1 --> que 1 --> processor 1
source 2 --> que 2 --> processor 2

I hope my problem is clear enough, if there are questions let me know. I didn't succeed to attatch my model.

Hello Guus,

I do not understand the second part of your question, but I think you should take a look at the pull requirement of the processor.
Connect processor 1 only to queue 1 and processor 2 to both queues. It is important that you have the first port of processor 2 connected to queue 2 and the second to queue 1. Then you set the pull requirement of processor 2 to any port.
I hope this hint might help you solve your problem.

First thanks for your quick reaction. Yes that's the part I already did, the problem is that processor only items from the que pull when less than 5 items are on the processor. if the capacity from the processor is 10. that's the restriction it has to have. get it?

Hello Guus,

Take a look at the Conditional Port option in the pull requirement from processor 2. Here you can put a condition when it will pull from the different ports.

Hi,

I can't get it to work, I've tried to write some codes but they don't work.

Guus,

Here is a sample model. The only thing I did was write code on the pull from port trigger on the second processor. It has the condition that if there is anything in it's own queue it will pull from there. If there is nothing in it's own queue it will look if there are products in the other queue and if it's own content is smaller then 16 then it will pull from the other queue. If not it will pull from its own queue.

See if this does what you want.

Thx! this is where I was looking for!
