2.16 Timer, Counter (Out & Reset)
Program example:
2.16.1Basic Timers, Retentive Timers And
Counters
These devices can all be reset at any time by
driving the RST instruction (with the number
ofthedevicetobereset).
On resetting, all active contacts, coils and
current value registers are reset for the
selected device. In the example, T246, a
1msec retentive timer, is activate while X1 is
ON. When the current value of T246 reaches
the preset ‘K’ value, i.e. 1234, the timer coil for
T246 will be activated. This drives the NO
contact ON. Hence, Y0 is switched ON.
Turning ON X0 will reset timer T246 in the
manner described previously.
Because the T246 contacts are reset, the
output Y0 will be turned OFF.
