80 ADVISE_ ENABLE Enabled ADVISE_ ALM alarm conditions. Corresponds bit for bit to 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.
81 ADVISE_ MASK Mask of ADVISE_ ALM. Corresponds bit for bit to ADVISE_ ACTIVE. A bit on means that the condition is
masked out from alarming.
82 ADVISE_ ACTIVE Enumerated list of advisory conditions within a device.
83 HEALTH_ INDEX Alarm indicating advisory alarms. These conditions do not have a direct impact on the process or device
integrity.
84 PWA_ SIMULATE Parameter representing the overall health of the device, 100 being perfect and 1 being non-functioning.
The value will be set based on the active PWA alarms in accordance with the requirements stated in
"Device Alerts and Health Index PlantWeb Implementation Rules". Each device may implement its own
unique mapping between the PWA parameters and HEALTH_ INDEX although a default mapping will be
available based on the following rules.
HEALTH_ INDEX will be set based on the highest priority PWA *_ ACTIVE bit as follows:
FAILED_ ACTIVE: 0 to 31 - HEALTH_ INDEX = 10
MAINT_ ACTIVE: 27 to 31 - HEALTH_ INDEX = 20
MAINT_ ACTIVE: 22 to 26 - HEALTH_ INDEX = 30
MAINT_ ACTIVE: 16 to 21 - HEALTH_ INDEX = 40
MAINT_ ACTIVE: 10 to 15 - HEALTH_ INDEX = 50
MAINT_ ACTIVE: 5 to 9 - HEALTH_ INDEX = 60
MAINT_ ACTIVE: 0 to 4 - HEALTH_ INDEX = 70
ADVISE_ ACTIVE: 16 to 31 - HEALTH_ INDEX = 80
ADVISE_ ACTIVE: 0 to 15 - HEALTH_ INDEX = 90
NONE - HEALTH_ INDEX = 100
85 ADVISE_ ACTIVE Allows direct writes to the PlantWeb Alert "ACTIVE" parameters and RB.DETAILED_STATUS. The
simulate switch must be "ON' and the SIMULATE_STATE must be "Switch on, simulation allowed" before
PWA_SIMULATE can be active.
