Output record flags

When the Application Calculation Engine (ACE) writes to a telemetered field, it has the ability to update the fresh flag and the error flag on that record.

If the calculation fails, the record is put into error. If the ACE record is flagged to update the fresh status, the output is set to stale when a calculation fails.

Flags can similarly be changed if a PubSub input has no publisher; the error flag is set to yes and the fresh flag is set to no. The ACE record needs to be flagged to update the fresh status.

When updatefresh is active, the ACE examines all of the inputs and calculates the fresh flag for the output record. The algorithm for each parameter is as follows:

If this parameter = output field

Continue to next parameter

Else

If this parameter is configured

If this parameter has a fresh flag

AndFresh = AndFresh AND parameter.fresh

OrFresh = OrFresh OR parameter.fresh

End If

End If

End If

End For Loop

If Using AND For Fresh

Output.fresh = ANDFresh

Else

Output.fresh = ORFresh

End If
