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
Hello Abhijit,
DeltaV has this functionality built-in. Create a flashing visibility on a box in your overview graphic with the following expression: "dvsys.THISUSER/AREAALMCNT[@index0@].F_CV > 0". Replace the "index0" with "index#" where # is the order in which the Area was created in the system. For example, "index0" will be AREA_A since it is created by default.
Regards,
Brian
