alarms
The alarms and recommended actions should be used in conjunction with Table 7-2.
The Resource Block will act as a coordinator for PlantWeb alarms. 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. 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 four 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 alarm to be sent. Below is a list of the failures with the
highest priority first.
1. NV memory failure
2. Sensor board electronics failure
3. Output board electronics failure
4. Thermocouple failure (MTA only)
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 alarming priority of the FAILED_ALM, see “Alarm priority” on page 17. 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.
