The Packaging Panel
Panel modules
This chapter contains a detailed description of each of the Packaging panel modules,
including prompt descriptions and remarks on module usage.
Actions module
D ESCRIPTION
The Actions module is useful for modeling discrete entity logic that alters the status of the
system, but which is not directly dependent upon equipment sensors or controls. When an
entity enters this module, it performs the set of actions defined in the Actions repeat
group. The Actions module is similar to the Actions dialog box found in the Controls and
Sensors dialog boxes of Machines, Conveyors, and Palletizers. There is no time delay
associated with this module.
R EMARKS
The Actions dialog boxes found in the Controls and Sensors dialog boxes of Machines,
Conveyors, and Palletizers allow you to alter system status when controls and/or sensors
are activated. The Actions module provides similar functionality as those Actions dialog
boxes in the equipment modules. It provides additional system control by allowing you to
initiate actions using discrete entities.
The Arena Packaging template provides a set of Packaging variables for several of the
Packaging modules. These special-purpose variables are automatically defined and
assigned values over the course of a simulation by the Arena Packaging engine. They
reference both dynamic and static information of a modeled system (e.g., equipment run
speeds, input and output rates, conveyor accumulation levels, throughput quantities,
storage and tank levels, etc.).
Use the Update HiSpeedSim Variables action to make sure that all packaging-related
variables reflect the current state before using them. This is especially useful if you will be
making decisions based on variable values, writing them, or using them in calculations.
Note that the action is named “Update HiSpeedSim Variables” rather than “Update
Packaging Variables” to maintain compatibility with models built in earlier versions of the
software.
