Note
If status is set up to flag failure/warning you will see associated sensor degraded or failure alert.
3.4.5 Field Diagnostics Alerts
The Resource Block will act as a coordinator for Field Diagnostic Alerts. There will be four alarm
parameters (FD_FAILED_ALARM, FD_OFFSPEC_ALARM, FD_MAINT_ALARM, and
FD_CHECK_ALARM) that will contain information regarding some of the device errors that are
detected by the transmitter software. There will be a RECOMMENDED_ACTION parameter that
will be used to display the recommended action text for the highest priority alarm and a
HEALTH_INDEX parameters (0 - 100) indicating the overall health of the transmitter.
FD_FAILED_ALARM will have the highest priority followed by FD_OFFSPEC_ALARM,
FD_MAINT_ALARM and FD_CHECK_ALARM will be the lowest priority.
FD failed alarms
A failure alarm indicates a failure within a device that will make the device or some part of the
device non-operational. This implies that the device is in need of repair and must be fixed
immediately. There are five parameters associated with FD_FAILED_ALARMS specifically, they
are described below.
FD_FAILED_MAP
FD_FAIL_MAP parameter maps conditions to be detected as active for FD_FAIL_ALARM
category. Thus the same condition may be active in all, some, or none of the 4 alarm categories.
Below is a list of the failures with the highest priority first.
Failed Sensor 8 Failure Verify the Sensor 8 Instrument process is within the Sensor
range and/or confirm sensor configuration and wiring.
Failed Body Temperature
Failure
Verify the ambient temperature is within the operating limits
of this device. If condition persists, replace the device.
Failed Hardware/Software
Incompatible
Contact Service Center to verify the Device Information
(RESOURCE.HARDWARE_REV, AND
RESOURCE.RB_SFTWR_REV_ALL).
Failed Memory Error Restart the transmitter by writing the RESTART parameter to
4 - Restart Processor. If condition persists, replace the
transmitter.
Failed Electronics Failure Electronics failure has occurred. Restart the transmitter. If
condition persists, replace the transmitter.
Failed ASIC Failure ASIC failure has occurred. Restart the transmitter. If condition
persists, replace the transmitter.
