Note:
As for the sequence of the timer, the system may check its range automatically, if the repeated sequence or
out of the range, the system may alarm. The presetting time in timer is solidified in the ROM along with the
ladder diagram, so, the time of the timer only can be changed by modifying the ladder diagram file.
