Alerts The Resource Block will act as a coordinator for PlantWeb alerts. There will
be three alarm parameters (FAILED_ALARM, MAINT_ALARM, and
ADVISE_ALARM) which will contain information regarding some of the device
errors which are detected by the transmitter software. There will be a
RECOMMENDED_ACTION parameter which 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.
FAILED_ALARM will have the highest priority followed by MAINT_ALARM
and ADVISE_ALARM will be the lowest priority.
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 FAILED_ALARMS specifically, they are described below.
FAILED_ENABLED
This parameter contains a list of failures in the device which makes the
device non-operational that will cause an alert to be sent. Below is a list of
the failures with the highest priority first.
1. Electronics
2. NV Memory
3. HW / SW Incompatible
4. Primary Value
5. Secondary Value
FAILED_MASK
This parameter will mask any of the failed conditions listed in
FAILED_ENABLED. A bit on means that the condition is masked out from
alarming and will not be reported.
FAILED_PRI
Designates the alerting priority of the FAILED_ALM, see “Alarm Priority”
on page 4-25. The default is 0 and the recommended value are between 8
and 15.
FAILED_ACTIVE
This parameter displays which of the alarms is active. Only the alarm with
the highest priority will be displayed. This priority is not the same as the
FAILED_PRI parameter described above. This priority 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.
