High-speed Counters
Section 5-1
Auxiliary Area Data
Allocation
Counter Input Modes
Differential Phase Mode
(4x)
The differential phase mode uses two phase signals (phase A and phase B)
and increments/decrements the count according to the status of these two
signals.
Conditions for Incrementing/Decrementing the Count
Pulse + Direction Mode
The pulse + direction mode uses a direction signal input and pulse signal
input. The count is incremented or decremented depending on the status (ON
or OFF) of the direction signal.
