Alarms The alarms and recommended actions should be used in conjunction with
Section 2: Troubleshooting.
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.
NOTE
PlantWeb alerts for ADB and mass flow cannot be simulated.
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 alarm to be sent. Below is a list
of the failures with the highest priority first.
1. Memory Failure
2. NV Memory Failure
3. Primary Value Failure
4. Secondary Value Failure
5. Sensor Module Memory Failure
6. Sensor Module Failure
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 3-15. 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.
