F1
Individual
inputs
Counts input A as incremental pulses and input B as
decremental pulses. The count is incremented on the
rising edge of input A and decremented on the rising
edge of input B. If both inputs rise at the same time, the
count is not changed. The count is incremented when
input B is later than input A and decremented when input
B is earlier than input A.
Counting the number of people entering an area
F2
Phase dif-
ferential in-
puts
This function is normally used when connected to an
incremental rotary encoder. The count is incremented on
the falling edge of input B when input A is OFF. The count
is decremented on the rising edge of input B when input
A is OFF.
