Analog Input module

Figure 4-30: Wiring for Up/Down Counting

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 signal is within logic level "1", the counter value increases.

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

Note: If users select TTL mode and don't connect C0B+ C0B-, the counter value will increase. If users select Isolated mode and don't connect C0B+ C0B-, the counter value will decrease.
