How to make a process read the piece label and not the pallet label?

Hello.

In my simulation I want the processors from 1-7 to read the piece's label, however, it is reading the pallet that will transport the piece through the conveyors.

I do not know why it is trying to read the pallet's label and not the piece label.

I'm attaching a picture and my simulation.

I hope you can help me and I thank you in advance.

I also notice your headers for the conveyor entry transfers' orirentation trigger are from 21.0.1 which were changed in 21.0.2 where they should then read:

Object current = ownerobject(c);
Conveyor conveyor = param(1);
Object item = param(2);
Conveyor.Item conveyorItem = conveyor.itemData[item];

and not:

Object current = param(1);
Conveyor conveyor = param(2);
Object item = param(3);
Conveyor.Item conveyorItem = conveyor.itemData[item];

As Jason has said, item.first.Type is the correct way to read the item label.

The logic behind this is that all objects like conveyors or processors in FlexSim read the item that is entering/inside the object, in this case the pallet.

With "item" in this case you are referencing the pallet. With "item.first", you are referencing the item inside the pallet, and with "item.first.Type" you are referencing the label Type of the item inside the pallet.

This logic can work with objects inside objects inside objects, like a box inside a tote inside a Pallet. To read the box label in this case you need to use item.first.first.Type (like Pallet.Tote.box.Type)

And for those of you, who want to read the second, third box label Type value, you do it with the property subnodes.

item.subnodes[2].Type
item.subnodes[3].Type

and in a nested structure like Pallet.Tote.Box.Type

item.subnodes[3].subnodes[2].Type

for 3rd Tote, 2nd Box in a Pallet.
