3.4.3. 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 transmitter. 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.

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. These parameters are mapped by default with
FAILED_MAPPED: Sensor Board Fault, Communication Board Fault, Sensor
Communication Fault, Reference reflection not found, model number mismatch,
Measurement failure/fault.
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.

diagnostics indicate deviations from measured or set values due to internal
problems in the device or process characteristics.
Output signal temporarily invalid due to on-going work on the device.
