(1) Precautions for using timer
The following shows precautions when using timers.
For details, refer to the QnUCPU User's Manual (Function Explanation, Program Fundamentals).
(a) QnUCPU/QnASCPU timer ladder programming method
Set the number of points for the timer and retentive timer in the Device setting of the parameter
setting.
To use the low-speed timer, high-speed timer, retentive timer and high-speed retentive timer
separately, add "H" or "S" to the OUT instruction in programming.
Ex.)Low-speed timer:OUTT0Kn
High-speed timer:OUTHT0 Kn
Low-speed retentive timer:OUT ST0 Kn
High-speed retentive timer :OUTHST0 Kn
