The Scheduled Stops option in Machine, Palletizer, and Conveyor modules is where
you define scheduled downtimes for those elements.

Dynamic line control
Dynamic line control is often necessary for regulating or directing particular situations
and events in a system. It can be a critical factor of a line’s design, impacting system
utilization and performance.
The Arena Packaging template has options for placing controls and sensors on equip-
ment such that the details of your functional control system can be incorporated into
the model logic. A control is a function that monitors system status for one or more
conditions. When a condition is true, one or more actions can be taken (e.g., change
the speed factor of a machine). Sensors are devices that can be placed anywhere along
the lengths of conveyors and tanks to monitor accumulation levels of units or fluids.
When a sensor is either covered or uncovered, it is triggered and one or more actions
can be taken.
The Controls option in Machine, Palletizer, and Conveyor modules is where you
define controls for those elements. The Sensors option in Conveyor and Tank modules
is where you define sensors for those elements.
The Actions module is also available for performing actions on the system using
discrete entities and logic rather than controls or sensors.
