Specifying the channel number and number of moving average [S1]
Specify the channel number of the high−speed counter and number of moving average.
If necessary, specify the measurement of pulse period.

Measurement of
pulse period

0: Pulse period is not measured.
1: Pulse period is measured in 1us unit.
2: Pulse period is measured in 1ms unit.
3: Pulse period is measured in 1us unit and 1 ms unit.
Measurement limit process for period measurement
The measurement limit process is a function which sets the measurement value to −1 when the period
measurement has not completed in a given amount of time.
When measuring period in 1us unit
When measurement timer overflow has occurred
The measurement value is set to −1 when a short period could be measured although a time more than
174ms has elapsed after the previous measurement request.
When measurement has not completed
The measurement value is set to −1 when measurement has not completed although a time more than
350ms has elapsed after the previous request.
Even when measurement has completed after that, the result is disregarded and measurement is requested
again.
When measuring period in 1ms unit
The elapsed value is set to −1 when the result of checking the period measurement counter _plsCycleTime0
has exceeded the measurement limit specified for the above n.
Even when measurement has completed after that, the data is disregarded and measurement is requested
again.
Specify the counting period for the number of pulses. [S2]
Specify it in 1ms unit. K1 to K5000 (1ms to 5s)
Specifying the starting number of the destination area where the pulse is output. [D]
Specify the starting number of the destination area where the pulse is output.

The latest value is stored with the measurement period
specified by S2.
The period of 1 pulse right after this instruction is executed is
stored.
The latest value is updated every time the period of 1 pulse is
measured after the execution of this instruction.
