the motors. In the MagneMover LITE transport system, the guideway is the
integral rails that are mounted on the motors.
Hall Effect Sensor: A transducer that varies its output in response to changes in a magnetic field.
Hall Effect Sensors (HES) are used by MagneMotion LSMs for vehicle posi-
tioning and speed detection.
Headway: The space that is maintained before a vehicle to make sure that the vehicle is
able to stop safely. See Brick-wall Headway.
High-Level Controller: The application in a node controller that communicates with the host con-
troller. Only one node controller per HLC Control Group runs the high-level
controller application. In a transport system with only one node controller, it
runs both the node controller and high-level controller applications.
HLC: See High-Level Controller.
HLC Control Group: The portion of a multi-HLC LSM transport system under control of a specific
HLC.
Host Application: The software on the host controller that provides monitoring and control of the
transport system.
Host Control Session: A session between a host controller application (such as the NCHost TCP
Interface Utility) and an HLC that allows control of all aspects of transport sys-
tem operation. The Host Control Session also allows active monitoring of
transport system status.
Host Controller: The user-supplied controller that provides control and sequencing for the oper-
ation of the transport system.
Host Status Session: A session between a host controller application (such as the NCHost TCP
Interface Utility) and an HLC that only provides active monitoring of transport
system status.
ICT: See Independent Cart Technology.
ID: The software labels used to identify various components of the transport sys-
tem to make sure proper execution of commands involving vehicle position,
vehicle destination, and transport system configuration. ID types include vehi-
cle and path.
Independent Cart Technology: A programmable intelligent conveyor system that uses linear syn-
chronous motors for moving multiple independently controlled vehicles.
Interlock: A user-supplied circuit that is used to stop motion in the transport system. It is
wired through the digital I/O on the Node Controller.
Inverter: The hardware that converts DC from the propulsion power bus to pulse-width
modulated AC to energize the coils in a Motor Block and contains the Master
and the Inverter for QSHT motors. See Drive.
Keep-out Area: A unidirectional area of a Path. A vehicle that is moving in the specified direc-
tion of the area is not allowed to enter the area unless it has permission from
the motors to either move past or stop within the area. Once a vehicle enters the
