scan analysis modes
5.5.3 Analysis Mode Selection
The MINI-ARRAY controller is a versatile microcontroller-based module that may be
configured using a PC-compatible computer running Windows ® XP, Vista, or 7
and the Banner-supplied software via the built-in RS-232 or RS-485 interface. The
Banner MINI-ARRAY System can be programmed for any one or two of the following
Scan Analysis Modes (see Figure 5-13 for examples):
All Data (ALL): The controller passes all beam condition data for every scan to the
serial interface for analysis by a host computer or controller.
First Beam Blocked (FBB): The controller identifies the location of the first beam
blocked. Beams are numbered, beginning with the cabled end of the sensor, and
continuing in sequence to the top end of the sensor.
Last Beam Blocked (LBB): The controller identifies the location of the last beam
blocked.
Total Beams Blocked (TBB): The controller totals the number of blocked beams.
Contiguous Beams Blocked (CBB): The controller totals the number of contiguous
beams blocked in each group of blocked beams along the length of the light screen and
registers the maximum value.
First Beam Made (FBM): The controller identifies the location of the first clear beam.
Last Beam Made (LBM): The controller identifies the location of the last clear beam.
Total Beams Made (TBM): The controller totals the number of clear beams.
Contiguous Beams Made (CBM): The controller totals the number of contiguous
clear beams in each group of clear beams along the length of the light screen and
registers the maximum value.
Vehicle Separation (VHS) (discrete output models only): Controller output #1 is
energized when six or more continuous inches of light screen length are blocked (i.e.,
contiguous beams blocked), and de-energizes when all beams are clear. This mode is
typically used for vehicle sensing in toll booth applications.
Segment (SEG) (controller models MAC16N-1 and MAC16P-1 only): The controller
segments the array into regions and allows the user to partition the array. The user
defines contiguous segments. Once the segments are defined, the Controller monitors
each segment for blocked beams within each segment. If one or more beams are
blocked within any segment, the output corresponding to that segment will respond.
Transition (TRN) (controller models MAC16N-1 and MAC16P-1 only): The controller
counts transitions, which are used to count objects. This mode counts both clear-to-
blocked and blocked-to-clear transitions. For example, if an object blocks beams 20
through 30, the TRN mode will count two transitions. If an additional object blocks
beams 35 through 40, then the TRN mode will count four transitions.
