NOTE!
The counter and frequency inputs update four times
per second (4Hz), except the Linear 0 to 300 (Hz) input
type, which updates once every 25 seconds (.04Hz).
The update rate of all other input types depends on
the module. See Chapter 7, Specifications.
Input Filter
This parameter determines the time constant for the filter
applied during the conversion of
Input, Raw Counts
to
Input Value
.
The input value responds to a step change by going to
approximately 2/3 of its final value, within the number of scans
set here. A larger number yields a slower, or more damped,
response to changes as measured by the sensor.
Temperature Scale
This register sets the units used during the conversion of
Input,
Raw Counts
to
Input Value
. This parameter applies only to
temperature sensor input types.
lists and describes
the possible settings.

Temperature Scale Conversion
Input Signal Low (Input Signal Lo)
This is the input signal level that corresponds to the low
process value set in
Process Variable Low
(see below). For custom
linear inputs, this parameter is the lowest level signal the
sensor or encoder will supply. Typically, this corresponds to the
lowest process variable to be measured. The units and range for
this parameter correlate to the selected
Input Type
. See
Setting Input Signal Lo and Input Signal
Input Signal High (Input Signal Hi)
This is the input signal level that corresponds to the high
process value set in
Process Variable High
(see below). For custom
linear inputs, this parameter is the highest level signal the
sensor or encoder will supply. Typically, this corresponds to the
highest process variable to be measured. The units and range
for this parameter correlate to the selected
Input Type
. See
