2) Clock Pulse
The desired execution condition can be combined with a clock pulse to mimic the clock pulse (0.1 s, 0.2
s, or 1.0 s).
Timer reset method
There are two methods for resetting a timer instruction.
1. Turn OFF the execution condition for the timer instruction.
The timer will be reset when its execution condition turns OFF.
The timer will start timing again when its execution condition turns ON.
With this method, a timer cannot be reset and then restarted within the same cycle.
2. Use the RESET TIMER/COUNTER instruction.
The specified instruction will be reset when the RESET TIMER/COUNTER instruction (CNR/CNRX) is
executed.
