This parameter is used to define the scan mode for the frequency
measurement.
1000 ms:
This mode provides a normal update rate and normal accuracy.
The acceptable frequency range for the input signal is 1 Hz to 3 kHz
(± 1 Hz error). This mode can be used when the pulse width (signal
source) contains small errors since the measurement is based on the
pulse count.
100 ms:
This mode provides a fast update rate, but the accuracy is low.
The acceptable frequency range for the input signal is 100 Hz to 3 kHz
(± 10 Hz error).This mode can be used when the pulse width (signal
source) contains small errors since the measurement is based on the
pulse count.
Single-pulse:
This mode provides the highest accuracy but can only be used for a
stable signal.
The data update rate depends on the signal frequency and the
acceptable signal frequency range for the input signal is 0.01 Hz to 3.5
kHz (± 0.01 Hz error).This mode can only be used when the pulse
width (signal source) is stable since the measurement is based on the
width of a single pulse.
1 ==> No Average is used
2 ==> Uses the average of 2 continuous sample values
4 ==> Uses the average of 4 continuous sample values
8 ==> Uses the average of 8 continuous sample values
Dynamic: Dynamic I/O type based on DO requests.
Static: Static I/O type by configuration (web or Modbus).
This parameter is used to set the Universal DIO channels to DI or DO Port.
1 ==> DI; 0 ==> DO
