DOR Daily Calculation Methodology
DOR Daily Calculation Methodology
When the daily calculate EXE fires, it gets what items to calculate by
SELECT Pid.*
FROM dbo.tblPLC_PLCid AS Pid
WHERE (Pid.TrackDataOnceDaily = 1)
AND (LEFT(ISNULL(Pid.PLC_SubTagName, ' '), 1) = '=')
AND Pid.DisplayItNow=1
It will forcibly calculate all daily items that have a formula beginning with =
When calculating, if any of the PLCid components of a formula are disabled, IE: DisplayItNow=False, they will be replaced with 0.0
Logic prior to 3/20/2023
Find all datapoints that are from external datasources or manual entries and calculate their dependents, whether disabled or not.
