Phase_Failures named set

The phase_failures named set is used in the Failure_Monitor composite block in the phase logic. When a failure register is set, based on your failure logic, the associated named set string is displayed in the Batch Operator Interface window.

For example, when the phase is running properly, the Failure_Monitor register is set to 0 and DeltaV Operate displays the word OK. When the phase fails, the Failure_Monitor register is set to 255 and DeltaV Operate displays the word Failed.

You can add your own entries to phase_failures to denote certain process-specific failure causes.

Note that the hold logic executes from the first hold step when the FAIL_INDEX changes to a higher value, even when the hold logic is currently running (holding). Therefore, the Phase_Failures named set values should be configured so that the most serious condition has the highest value.
