Good morning PI users!
I've recently been trying to include more and more information from our SQL database into our Process displays (i.e. fault summation and current active step). However, I'm at an impasse trying to include SQL information into a trend along with other tags. For instance, using the data below as an example I have a value that is tied to an ODBC Data Set which performs a query to pull the Count(Fault 2) messages since midnight. So it correctly shows 3 as the value of faults.
Message Time
Fault 1 11:20 AM
Fault 2 10:30 AM
Fault 9 10:02 AM
Fault 2 9:05 AM
Fault 2 8:30 AM
Fault 5 7:45 AM
However, in order to see the relationship between a specific fault message and the temperature set as a PI tag, I would like to have them both on the same trend to be able to see how they progressed throughout the night. When I graph the data set, it stays at a constant 3 [instead of 0 from midnight to 8:30AM, 1 from 8:30AM to 9:05AM, and so on]. Is there an efficient way to do this through VBA? I've tried Value.GetValue and putting it into a ListBox but it only compiles information as I have the display open.
Any advice or directional guidance would be greatly appreciated.
Thanks!
