Choosing a Linear Input Type
To set up a linear input first choose an Input Type. There are
seven user selectable linear input types: three input types for
voltage signals, one for current, two for frequencies, and one for
counts. Pick an Input Type with the appropriate signal type
(voltage, current, frequency or counts). Also choose an Input Type
with the appropriate range and sensitivity for the sensor.
Generally, the appropriate Input Type for Soft Inputs is Linear
(Counts).
Table 3.3 Range and Sensitivity of the
Custom Linear Input Types
* Depends on module type. See Chapter 7, Specifications.
Setting Input Signal Lo and Input Signal Hi
After choosing the Input Type, set the Input Signal Lo and Input
Signal Hi. The Input Signal Lo is the lowest level signal the sensor
will supply. Typically this corresponds to the lowest process
variable to be measured. The Input Signal Hi is the highest level
signal the sensor will supply. Typically this corresponds to the
highest process variable to be measured.
Setting Engineering Units
Set the engineering units in which you will specify the PV Lo
and PV Hi. When used with linear inputs, the Units parameter is
for display only and has no effect on the process variable value
calculated or displayed.
Setting PV Lo and PV Hi
After setting the Input Signal Lo and Input Signal Hi, set the
corresponding PV Lo and PV Hi. The PV Lo is the process variable
measured when the sensor signal is at the level set in the Input
Signal Lo field. The PV Hi is the process variable measured when
