Hello lalit SD (STL for On-delay S5 Timer, called "S_ODT" in English mnemonics if LAD/FBD isused) will stop timing if the "S" input is off. Do not get confused by the fact that its actual time value remains steady at the last value when the "S" input goes off (this is how it is meant to be). The timerwill start timing again fromthe preset value "TV" when the "S" input goes ON again (see also the timing diagram that is available for it with the <F1> inbuilt help). Should you however obeserve that the Timercontinues to time down when the "S" input is off, then please check ifyou use (start) the same timer somewhere else in your program (which is something you must NOT do). I hope this helps |
Cheers |

I want a timer which should reset immediately as soon as the input goes low. |
