Free module
D ESCRIPTION
The Free module releases the entity’s most recently allocated transporter unit. If another
entity is waiting in a queue to request or allocate the transporter, the transporter will be
given to that entity. If there are no waiting entities at the time the transporter unit is freed,
the transporter will wait idle at the freeing entity’s station location, unless otherwise
specified in the Transporter module.

A part awaiting a shipping truck frees its forklift
„

Halt module
D ESCRIPTION

busy at the time when an entity enters the Halt module, the status is considered busy and
inactive until the entity that controls the transporter frees the unit. If the transporter is idle
at the time when an entity halts the transporter, it is set to inactive immediately. Once a
transporter unit has been halted, no entities will get control of the transporter until it is
activated.
T YPICAL USES
„
Stop a forklift for scheduled maintenance

Disable a broken gurney in an emergency room
