  • Hi, I am using a binary point for a compressor, and I want to know if is any possibility to extract this data and to trigger an alarm after 1000h of running:

    0_1500280464572_run hours.JPG

  • @georgestefan you can add an event detector to detect if it stays in the same state for x hours but that wont work if the compressor turns off and on obviously. I'm sure there is a way to do what you are asking via scripting. @phildunlap should be able to help you.

  • Hi George,

    There is! Runtime information is available in the StartsAndRuntimes object returned from the past() and previous() functions on data points in scripts.

    So, i could have a meta point like,

    var stats = p.past(DAY); //p is the variable name of the binary point in the context
    for(var k = 0; k <; k+=1) {
        if([k].value === true)
            return my.value +[k].runtime/3600000; //runtime given in milliseconds
    return my.value;

    running on a cron like 59 59 23 * * ? and it'll totalize once a day the hours run that day. Then you can put a limit detector on the meta point.

  • Thanks, I'll try this.

  • @phildunlap I've created a meta point like this and when I run the script it shows me the right value, but the limit detector didn't worked

    This is the meta point:

    And I've noticed this in my data base:

    Comp_Run_H it's the meta point from above.
    Can you tel me why I don't have any value returned?

  • This post is deleted!

  • Have you let this run over night? With that cron pattern it should only run on the last second of the day to produce a value.

  • Yes, that's right, at the last second of the day produce that value, I'm starting to see how this is working.
    Thanks again!
