Timer and Counter Instructions Section 3-6
When CIO 000001 is ON, the Completion Flags for counters C0003 to C0007
are turned OFF and the counters’ PVs are set to the maximum value of 9999.
3-6-10 Example Timer and Counter Applications
The following examples show various applications of timer and counter
instructions including long-term timers, a two-stage counter, ON/OFF delay,
one-shot bit, and flicker bit.
Example 1:
Long-term Timers The following program examples show three ways to create long-term timers
with standard TIM and CNT instructions.
Two TIM Instructions
In this example, two TIM instructions are combined to make a 30-minute
timer.
TIM and CNT Instructions
In this example, a TIM instruction and a CNT instruction are combined to
make a 500-second timer.
TIM 0001 generates a pulse every 5 s and CNT 0002 counts these pulses.
The set value for this combination is the timer interval
×
counter SV. In this
case, the timer SV would be 5 s
×
100 = 500 s. With this combination, the
long-term timer’s PV is actually the PV of a counter, which is maintained
through power interruptions.
