Field Diagnostics
The Resource block acts as a coordinator for alarms. There are four alarm parameters: Fail alarm,
Offspec alarm, Maintenance alarm, and Check alarm. It contains information of device errors that
are detected by the Remote Indicator. Based on the error detected, the device provides the
recommended actions; it is a read only parameter. It displays the recommended action text for the
reported alarms.
Table 14: Diagnostic Definitions
Name Description
Maintenance Although the output signal is valid, the wear reserve is nearly exhausted or a
function is soon restricted due to operational conditions. For example, build-
up of deposits.
Off
Specification
Indicates if the device is operating outside its specified range or internal
diagnostics indicate deviations from measured or set values due to internal
problems in the device or process characteristics.
Check
Function
Output signal temporarily invalid due to on-going work on the device.
Failed Output signal invalid due to malfunction in the field device or its peripherals.
FAILED_ALARMS
Failed alarms indicate a failure within a device that makes the device or some part of the device non-
operational. This implies that the device needs repair and must be fixed immediately.
• FAILED_MAPPED parameter contains a list of failures in the device which makes the device
non-operational that causes an alarm. There are four parameters mapped by default with
FAILED_MAPPED: Communication board fault, communications board over temperature,
low supply voltage, and high supply voltage.
• FAILED_MASK parameter masks any of the failed conditions listed in FAILED_MAPPED.
A bit on means that the condition is masked out from alarming and is not reported.
• FAILED_PRI parameter designates the alarming priority of FAILED_ALM. The default is 0.
• FAILED_ACTIVE parameter displays the alarms that are active.
• FAILED_ALM parameter indicates a failure within a device which makes the device non-
operational.
