Up/Down Counting
The Up/Down Counter Function offers two types of counting: Up Counting (increas-
ingly) and Down Counting (decreasingly). Up Counting: when C0A+ and C0A- sense
any input signals, the counter counts up.
Down Counting: when C0B+ and C0B- sense any input signals, the counter counts
down. On receiving Up and Down signal simultaneously, the counter will not perform
each specific counting accordingly, but will remain at the previous counting value,
since these simultaneous signals won't have any effect on counting values.

Note! If you need only one type of counting, connect C0A+ and C0A- for Up
Counting only; or connect C0B+ and C0B- for Down Counting only.
Bi-direction Counting
For implementing Bi-direction Counting, you need to connect C0B+/D+ and C0B-/D- to
implement the control function for Up/Down Counting. Up Counting: when the input sig-
nal is within logic level "1", the counter value increases.

Down Counting: when the input signal is within logic level "0", the counter value
decreases.
