In the following example, CNT 001 counts the number of times the 1-second
clock pulse bit (25502) goes from OFF to ON. Here again, 00000 is used to
control the times when CNT is operating.
Because in this example the SV for CNT 001 is 700, the Completion Flag for
CNT 002 turns ON when 1 second x 700 times, or 11 minutes and 40 sec-
onds have expired. This would result in 00202 being turned ON.

Caution The shorter clock pulses will not necessarily produce accurate timers be-
cause their short ON times might not be read accurately during longer cycles.
In particular, the 0.02-second and 0.1-second clock pulses should not be
used to create timers with CNT instructions.

Each TC number can be used as the definer in only one TIMER or COUNT-
ER instruction.
The CNTR(12) is a reversible, up/down circular counter, i.e., it is used to
count between zero and SV according to changes in two execution condi-
tions, those in the increment input (II) and those in the decrement input (DI).
