Precautions for using timers
The RCPU updates the current values of timers and turns on or off contacts of them at execution of the OUT T
Thus, if the current value of a timer becomes equal to or larger than the set value when the coil of the timer turns on, the
contact of the timer will turn on.
To create a program in which the operation of a timer contact triggers the operation of another timer, program the timers in
order from the one that operates last.
In the following cases, if a program is created in order of timer measurements, all timers turn on in the same scan.
• The value set to a high-speed timer is smaller than the scan time.
• The value set to a low-speed timer is 1.
