the discrete logic that represents the activities necessary to replenish the storage (for
example, a Server module). Then that entity could connect to the Add a Pallet connection
point. If you wanted to add several pallets at a time, instead of using the Add a Pallet
connection, you would connect to an Actions module and specify the Add Pallets to
Storage action.
Likewise, you can use discrete logic to keep a Palletizer’s storage full. Simply create an
entity every time it becomes full, then make a connection from the Storage is Full connec-
tion point to the discrete logic that represents the activities necessary to empty the storage
(for example a Process module). Then that entity could connect to the Remove a Pallet
connection point. If you wanted to remove several pallets at a time, then instead of using
the Remove a Pallet connection, you would connect to an Actions module and specify the
Remove Pallets from Storage action.
Refer to the Discrete Entity Logic dialog box in the Palletizer module for other related
options for creating discrete entities.
Switch module
D ESCRIPTION
The Switch module may be used to regulate the flow of a single incoming stream into two
outgoing streams (a “left” stream and “right” stream). The flow can be regulated either by
product waves, by discrete action, or by unit counts. There may be a delay time associated
with the switch.
R EMARKS
If Switch On Product Name is specified, any unlisted product name that comes through
the switch will always go to the left branch.
If the switch Type is Action, then a “Change Direction of Switch” action in an Actions
dialog box or the Actions module may be used to alter the direction of the switch.
Tank module
D ESCRIPTION
The Tank module may be used to represent a container or holding area for any fluid-like
material. It is typically used in combination with one or more valves and a filling
machine.
