Alert Reporting

For Field Diagnostic alerts to be reported to the operator console, they must pass four tests:
d Alerts must be active
d Reports must be selected in Feature Select
d Alert priority must be greater than 1
d Reporting must not be suppressed for those conditions that caused active alerts.
Features Selected in the Resource block determines if reporting by the instrument is supported. Refer to page 25 for
additional information on Features Selected.
Failed Priority (FAILED_PRI [RB 86]), Maintenance Priority (MAINT_PRI [RB 94]), and Advise Priority (ADVISE_PRI [RB
98]) determine the Field Diagnostic alert priorities. Although 16 priorities are available only three are actually
meaningful for Field Diagnostic alerts. If the priority is 0, no reporting occurs. If the priority is 1, reporting is simulated
within the instrument, but the alert is not actually reported over the bus. The alert condition is reported for priorities 2
through 15, with the higher priorities taking precedence over the lower priorities.
Failed Suppress (FAILED_MASK [RB 92]), Maintenance Suppress (MAINT_MASK [RB 96]), and Advise Suppress
(ADVISE_MASK [RB 100]) determine which of the alert conditions are suppressed so that they are not reported.

Field Diagnostic Alerts Set Block Status

If a Field Diagnostic Alert is active, the AO or DO Block Readback parameter status may change. This behavior is
controlled with the Field Diagnostic Alerts Set PV Status parameter in the transducer block
