  • 1 second blinking LED - output?

    Si does anyone have a timed blinking output sample? I don't want any inputs or anything, just a timer and a blinking output.

    I could not find anywhere such a simple program.

    I believe SP4 is a _1Second bit that can be used for this.

      Ok... so I would load the _1Second bit into the timer and switch the output?

      later edit: I can't seem to be loading a _1Second or anything else in the timer, except _errors... and some other values starting with _, but nu timing values.

        in the rung would have SP4 then your output. The SP4 will toggle every 1 second automatic. If only wanted out to blink when certain condition existed would put that condition in that rung also or output would flash every 1 second all the time

          Oh, ok, thanks. Even better, I don't have to initialize anything. I understand now how to use the preset timers. Thank you.

              --------------------] [---------------+--------------]^[--------------------------------(T1) {ON Tmr}
              C1 | T2
              |
              |
              +-------------] [---------------------------------(T2) {ON Tmr}
              | T1
              |
              +-------------]^[--------------------------------(OUT)
              T1 Y1
              Set T1 & T2 to any time period that you want, and you'll get a continuous blinking output as long as C1 is TRUE. T1 = 1 sec / T2 = 1 sed. gives Y1---> ONE second ON, ONE second OFF.
              ] [ = Normally OPEN contact / ]^[ = Normally CLOSED contact.
