Sensor module
D ESCRIPTION
The Sensor module defines a detection device that monitors the level of material in a tank
(Tank module). A sensor’s location is specified using the Tank Name, Location Type,
Level, or Percentage prompts.
A sensor is activated when its location is crossed in the Crossing Direction AND the
sensor is enabled. When the sensor is activated, one or more Actions may be executed.
Additionally, the Create Discrete Entity option may be used to create a discrete entity and
send it to custom logic.
The Initial State field specifies whether the sensor is enabled or disabled at the beginning
of the simulation run. If a sensor is disabled, it will be ignored and never activate. A
sensor may be enabled/disabled dynamically at any point during the simulation run by
assigning the SensorState (Sensor ID) variable.
T YPICAL USES
„
Defines a device to monitor tank level so decisions can be made based on sensor state
„
Defines a device to initiate action when a tank becomes full, empty, or some other
significant level is crossed
„
Defines a device to trigger re-ordering of material when stock runs low
„
Defines a device to start and stop reclamations from a pile based on inventory level
P ROMPTS
Prompt Description
Name The sensor’s identifier.
Tank Name The name of the tank where the sensor is located.
Level The level location of the sensor if Location Type is Specific Level.
Percentage (0-100) The percentage location of the sensor if Location Type is Percentage
Capacity.
Crossing Direction The sensor is activated (triggered) when its location is crossed in this
direction.
Initial State Specifies whether the sensor is enabled or disabled at the beginning of
the simulation run.
If Sensor is Activated:
Action Type Specifies the type of action to perform.
Regulator Name The name of the regulator to regulate.
