COUNTER
- There are 16 counters available. The count
can be entered directly or a register can be used.
Figure 12.29 - Counter Definition Screen
Two counter types can be selected.
Single Cycle Counter
- Counts each false to true transition of
the counter rung as one count. When the entered number of
counts is reached the counter output bit flag will be true and
stay true until the counter is reset to zero by the counter reset
coil going true. After the counter is reset the output bit flag
will be false. The counter can also be reset to zero at any
time with the counter reset coil.
Continuous Counter
- Counts each false to true transition of
the counter rung as one count. When the entered number of
counts is reached the counter output bit flag will be true for
one program scan only. The counter will then reset to zero
and the start counting again with a false to true transition of
the counter rung. The counter can also be reset at any time
with the counter reset coil.
