Input Measurement Setpoints
There are five setpoints per channel that are associated with the input and how the data is
measured. This section describes how changing these values could affect the measurement
accuracy.
Name Range

Input
Sensor
Type (IST)
0: Input Disabled
1: 0 to 5 Volt
2: 0 to 10 Volt
3: 0(4) to 20 Milliamp
4: PWM Duty Cycle
5: Frequency/RPM
6: 16-bit Counter
7: Digital (High)
1: 0 to 5 Volt
See section
1.3
for more details about
each input type.
Pulse Per
Revolution
0 to 1000
0
This setpoint is only used if the IST is set
to 5: Frequency/RPM, otherwise it is
ignored. If set to zero, the data is reported
in Hertz. If non-zero, the controller reports
the input as RPM.
Measuring
Window
IST = 5
100 to 10000ms
IST = 6
0 to 65535 pulses
1000ms
If IST is set to 5: Frequency/RPM, this
setpoint determines the period at which
the controller will measure the pulses to
determine the frequency.
If IST is set to 6: 16-Bit Counter, the
controller will measure the time (1ms
resolution) it takes for the number of
pulse in the measuring window to be
counted at the input.
If IST is set to anything else, this setpoint
is ignored.
