Note
This function monitors the input pulse’s frequency from the high-speed
counter movement value. The frequency is stored in A854 and A855. Status
Flag A858.06 can be checked to determine whether or not the frequency is
being measured.
The pulse input’s counter data display must be set to frequency measurement
(mode 2) in the System Setup in advance.
Frequency Measurement (Mode 2) Specifications
The present counter value can be latched at the rising edge of the latch signal
input and stored as the latch register value. Each time the counter value is
captured, the latch register value is overwritten with the new value and the old
value is lost.
