What timers actually do in CODESYS, is they remember the time you first called them, and then on every call they just check how much time passed (they don't stall!). Once the set time passes, they'll raise a flag on their output so you can perform some task. WebFlasher – Two Timer Variant. Here’s how it works: initially both timers are off, and their elapsed time values are set to zero. Timer 1 starts timing immediately. After 500 ms, Timer 1 is done timing and its output contact (sometimes called “done bit”) turns on. When this happens, Timer 2 starts timing, and the Flashing Light coil turns ... george new hope club
