Scan Mode
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 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 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.
Moving Average
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
Universal DIO
Force DI/DO type
(For ET-2254 only)
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
