Process history viewer

Hi,

I have a couple of questions, in the process history viewer,  what is ALARMS.MACK / OPERATOR / NEW VALUE = 1 telling me? is it that the alarm mute button has been pressed or that it has been acknowledged by my operator?

also how can I log in the process history viewer when the ACK ALL / SILENCE HORN / DISABLE HORN buttons have been pressed on the alarm banner at the bottom of the screen?

thx in advance

Lee.

  • MACK is the alarm field allowing you to acknowledge all of a module's alarms simultaneously.

    From BOL article "The ALARMS parameter"

    ...0 (NO) is the initial value after download.

    1 (YES) acknowledges all alarm parameters in the next execution cycle and resets to 0....

    To audit clicks of the buttons you cite, the simplest thing you can do is create a module with three parameters, ACKALL, SILENCEHORN, DISABLEHORN, and insert frswritevalue functions in the beginning of each of the scripts for the corresponding alarm banner buttons that sets/resets the parameter value.  This will trigger the event chronicle to record a parameter change when those buttons are pushed.

    I thought there was a way to skip the module and just write an event directly to the chronicle via operate, but I can't seem to find it.
