Dear friends,

I noticed a lot of PI Alarm Tags Status (Inherited/ Historical Tags from Previous Platform Operator) seems to be in "reverse order" when compared to the actual DCS Alarm Tag Status.

The previous PI Programmer asked me to just flip the 'digitalset' Attribute from "NormalTRIP" to "TRIPNormal" and check if the Value is 'True' (i.e. matches the Value in DCS), if yes then it is safe to flip the 'digitalset' Atrribute setting for all the Alarm and Status Tags that are affected.

 

For example, all the PI Tags below are showing a Reverse Alarm Status when compared to the actual DCS Alarm Status:

 

 

Is there another approach to check and rectify the above condition, or is the above method the best approach?
