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:
 Electronics Failure - Output Board
 Internal Communication Failure
 Memory Failure - Output Board
 Software Incompatibility Error
 Electronics Failure - Main Board
 Internal Temperature Critical
 Sensor Database Error
 Software Error
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.
ADVISE_MASK 81 0x00000000
(0x00000000)
Mask of ADVISE_ALM. Corresponds bit of bit to
ADVISE_ACTIVE. A bit on means that the condition is
masked out from alarming.
ADVISE_ACTIVE 82 0x00000000
(0x00000000)
Enumerated list of advisory conditions within a device.
ADVISE_ALM 83 Alarm indicating advisory alarms. These conditions do
not have a direct impact on the process or device
integrity.
HEALTH_INDEX 84 100 Parameter representing the overall health of the
device, 100 being perfect and 10 being
non-functioning. The value is based on the active PWA
alarms.
PWA_SIMULATE 85 0x00(Simulation off) Parameter allowing simulation of PWA alarms.
