DCS Alarm Propogation From Process Display to Overview Display

Hi,

There is a customer requirement where we have to show annunciation (flashing box) on overview graphics (say) for Area1 if there is any alarm active on the detailed process graphic of Area1.Basically, create a box per graphics on overview graphics and show annunciation if there is any alarm active on the graphics for this area.

Has anybody come across simillar requirement and any workaroud to achieve this?

P.S. - We can always 'logically OR' all the alarms from this display in a custome module and generate a flag to annunciate the box on overview graphics; but I am looking for more efficient method which can be used to achieve this requirement in DeltaV.

Thanks and Regards,

Abhijit

    Hi Brian,

    Thanks for the resolution. I tried using the expression above; but for some reason, the expression did not work as it is- however, when I tried using 'DVSYS.AREANAME/ALMCNT.F_CV > 0', it worked.

    Thanks for your help!

    Regards,

    Hello Abhijit,

    Great news! Your expression string makes more sense anyway as it is tied to the system rather than the user. I will be using your solution in the future. Thanks for the feedback and great work!

    Thanks,
    Brian
