Pull from Rack using List

Hi,

I trying to pull flowitems from usual Rack using List.

my pull condition is ...

'current Rack Dwell Time >= 100' (Present Rack's Dwell Time setting value)

'Global Variable RackPull == 1' (Global Variable RackPull means when Combiner's current state 'collecting', this condition set on 'EntryTransfer5')

But, it's not working. am i set values wrong?

how should i solve this problem?

@tanner.p

I hope you will solve this issue. I also met the same problem like above. The query command using filter can't do itself when using 'List' with Rack. Using 'Pull from List' with Rack has some problem?

I hope you will run the model attached. Jorg Vogel answered without running the model. He looks like to guide after only reading the questions without running the model. Many users not using English are not familiar with express the correct meaning about their issues.

I hope you will solve this issue. Thanks.

There is only one parameter you must set to get the model working:

List RackText1: Properties > Back Orders Tab

activate Reevaluate All Values On Push

Without this option the list will be evaluated only on model run start by the pull function of the entry transfer. Now the list backorders are evaluated every time a value enters the list.

Thanks @Matthew Gillespie for your answer here.

Thanks for your detail and kindness. @Jörg Vogel.

I checked the downstream re-evaluation feature in the rack. And if using Queue instead of Rack, the model shows it as hope.

I hope you will guide as this case after run the model. A end-user not using English is not familiar with expression his correct issue.

Thanks again.
