Unknown type Slot in declaration of variable

[ FlexSim 20.2.3 ]

I'd like to write a code to get a storage slot for a Item. I can't get the syntax right. Why the following gives me an error:

Slot MySlot; // This gives an error: "Unknown type Slot in declaration of variable MySlot"

Slot = getSlot("1--01-1-1");

Hi Tomi,

The class name is actually Storage.Slot. Unfortunately FlexSim highlights Slot so it seems like valid code but it should actually be

Storage.Slot MySlot = getSlot("1--01-1-1");

Hi @Mischa Spelt

Thanks for the answer. I was able to get the syntax right but still i can't get the model right. I'd like to route all Items to certain slot thru ProcessFlow. How do I do that? I don't know what there should be in the Unload-Station field.

Pls see the attached model

asrs_test.fsm

For the unload station, you should use the rack that the slot belongs to. Since the slot is a reference to a variable in the Rack's attribute tree, you can simply use

ownerobject( token.Slot )

as the station:

However, just calling getSlot doesn't assign the item to the slot. It's better if you use the Find Slot activity from the Warehousing section of the library, as that will make a reservation:

As in this updated model: asrs-test-MS.fsm
