    Default Runtime watchdog

    Hi...

    Any one know if there is a function in Zenon where it is posible to make a watchdog function over the runtime???
    My idear was to generate a puls inside the runtime and send that to PLC and then let the PLC supervise the runtime..

    Hi

    I don't know what you are exactly looking for, but you can use timed events that are executed cyclic with the "Time Control" or also use the Scheduler or Production & Facility Scheduler.

    best regards

    Hi,

    if you change the execution type to "cyclic oly on that day" or "cyclic from that day on" (at least there has to be a cyclic in it ;D) then it should be possible to change the interval.

    The property help usually says it all:
    from that day: The function is executed from the defined day every day at the defined time.
    only on that day: The function is executed once on the defined day at the defined time.
    cyclic from that day on: The function is executed cyclically from the defined day in the defined interval.
    cyclic only on that day: The function is executed cyclically only on the defined weekday in the defined interval.
    So at the cyclic options you also have to use the interval, otherwise it is greyed.


    best regards
