Resource Block
H.2.1 Plantweb 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_AC-
TION 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
ADVISE_ENABLE 80 0x10000000
(Plantweb
™
Alerts
Simulation
Active)
Enabled ADVISE_ALM alarm conditions.
Corresponds bit for bit to the ADVISE_ACTIVE. A
bit on means that the corresponding alarm
condition is enabled and will be detected. A bit
off means the corresponding alarm condition is
disabled and will not be detected.
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 N/A 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.
