  • Countdown Timer

    I downloaded the countdown timer on the example programs and it doesn't countdown it counts up. I did make it so that a user could enter a time for the timer but i cant figure out how to get the timer to not reset after the set time is finished. Does anyone have logic for a countdown timer that has minutes and seconds and then activates an output and stops when finished.
    Thanks

      If you are using EP-MISC-004 in the P3000 column..
      Are you monitoring the correct tag. The timer and counter have their accumulator tags, and then there are separate COUNT/TIME down tags in MATH instructions.

      If you are using EP-MISC-029, I have not looked at it. Maybe I can later.

      [edit]
      EP-MISC-029 is questionable with respect to the project description on the webpage.
      I added a make-do project image

        I am using a productivity 1000. In the above program could i use another contact to turn the timer on after the value is entered.
