Module Operation Chapter 2
To invoke the Up/Down Count function by using the output tag method, use the
Counter[x]CountDown output tag to define the direction of Counter[x] as
shown in Figure 4
. By default, the count direction is up.
Figure 4 - Counter[x]CountDown Output Tag
IMPORTANT
The Counter[x].CountDown output tag is active only if the Up/Down Count
function is not tied to Counter[x] via a hardware input. If a hardware input is
tied to Counter[x], the hardware input overrides the value of the
Counter[x].CountDown output tag.
0 = Count direction is up,
level-sensitive.
1 = Count direction is down,
level-sensitive.
