Unpack - If this button is checked, the separator will assume that the flowitem that entered contains other flowitems that need to be removed.
Split - If this button is checked, the separator will make duplicate copies of the entering flowitem.
Convey Items Across separator Length - If checked, flowitems will travel across the separator during their process time.
Split/Unpack Quantity - This picklist returns how many flowitems will be unpacked or duplicated by the separator. Refer to the split quantity picklist.
Recycle From (Split mode only) - In split mode, the flowitems that are created can be pulled from recycled flowitems rather than creating a new copy. You can use this option to specify what type of flowitem should be created. To learn more about recycling, refer to the Sink Page.
