Section 4: FOUNDATION fieldbus Configuration
April 2014
Foundation™ fieldbus configuration
FAILED_PRI
Designates the alerting priority of the FAILED_ALM, see “Alarm priority” on page 159. The
default is 0, and the recommended values are between 8 and 15.
FAILED_ACTIVE
This parameter displays the active alarms. Only the highest priority alarm will be displayed. This
priority is not the same as the FAILED_PRI parameter described above, but is hard coded within
the device and is not user configurable.
FAILED_ALM
Alarm indicating a failure within a device which makes the device non-operational.
MAINT_ALARMS
A maintenance alarm indicates the device, or some part of the device, needs maintenance soon.
If the condition is ignored, the device will eventually fail. There are five parameters associated
with MAINT_ALARMS:
MAINT_ENABLED
The MAINT_ENABLED parameter contains a list of conditions indicating the device, or some part
of the device, needs maintenance soon.
Below is a list of the conditions, with the highest priority first.
1. Primary Value Degraded
2. Secondary Value Degraded
3. Configuration Error
4. Calibration Error
MAINT_MASK
The MAINT_MASK parameter masks any of the failed conditions listed in MAINT_ENABLED. A bit
on means that the condition is masked out from alarming and will not be reported.
MAINT_PRI
MAINT_PRI designates the alarming priority of the MAINT_ALM, see “Process alarms” on
page 159. The default is 0 and the recommended values is 3 to 7.
MAINT_ACTIVE
The MAINT_ACTIVE parameter displays which of the alarms is active. Only the condition with
the highest priority will be displayed. This priority is not the same as the MAINT_PRI parameter
described above. This priority is hard coded within the device and is not user configurable.
MAINT_ALM
An alarm indicating the device needs maintenance soon. If the condition is ignored, the device
will eventually fail.
Advisory alarms
An advisory alarm indicates informative conditions that do not have a direct impact on the
device's primary functions. There are five parameters associated with ADVISE_ALARMS. They
are described below.
