Scanning Methods

Control Mode
Selection
Continuous
scanning
Gate Mode: scanning controlled by applying 10-30V dc to GATE input
Host Mode: scanning controlled by host computer or PLC
Serial
Communication
Defines
baud rate and controller I.D.
Serial Transmission
Activates
serial data transmission and
specifies
data format.
After
a PSF is
configured,
it may be sent to the controller. The PSF may also be saved for call-up at a later
time.
Many PSFs may be saved
within PC
files
for quick controller
configuration
whenever a
configuration
change is required.
5.4.1 Assigning the Analysis Mode
The MINI-ARRAY controller is a
versatile
microcontroller-based module that may be
configured
using a
PC-compatible
computer running
Windows
®
and the Banner-supplied
software
via the built-in RS-232 or RS-485 interface.
You may program one or two Measurement Analysis modes. Assign Meas1 or Meas2 to one or both outputs. The Banner MINI-ARRAY
System can be programmed for any one or two of the following Scan Analysis Modes:
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.
