Hello, Instead of using timer you could try with reading of CPU clock and on the right time to execute some logic. Look at http://support.automation.siemens.com/WW/view/en/21222026 But if you want to use existing logic with timers, look at SFC/SFB library instructions, you can look at SFB4, "TON", which uses a Time datatype for the preset and accumulated time of the timer, TIME is an IEC32-bit datatype, actually an integer value reperesenting milliseconds, which makes it very useful for timer math, but also gives you a range of up to 24 days.
