Function
The pointer word is used to set the
starting location in the Unit memory
map for the I/O READ and I/O
WRITE instructions that are executed
in ladder logic in the CPU Unit. This
allows the user to selectively read
and write parts of the Unit memory
map.
These bits are turned ON by the user
to enable/disable each input point.
The Unit scans only input points that
are enabled. The default value is all
input points enabled.
These bits are turned ON or OFF by
the user to select the data format
used by each input point.
ON:
OFF:
This selection specifies the format of
the conversion data in words 01 to16.
BCD and binary can be used at the
same time for different input points.
NOTE: When specifying a data for-
mat for an input point, all Unit
memory map words for that specific
input point should have the same for-
mat. Mixing formats for an input point
will cause erroneous results to be
reported.
The default value is BCD (ON) for all
input points.
These bits are turned ON by the user
to enable/disable the scaling function
for each input point. The default value
is disabled (OFF) for all input points.
These bits are turned ON by the user
to enable/disable the Averaging
function for each input point. The
default value is disabled (OFF) for all
input points.
These bits are turned ON by the user
to enable/disable the filtering function
for each input point. The default value
is disabled (OFF) for all input points.
These bits are turned ON by the user
to enable/disable the peak hold
function for each input point. The
default value is disabled (OFF) for all
input points.
These bits are turned ON by the user
to enable/disable the low alarm
function for each input point. The
default value is disabled (OFF) for all
input points.
