Table C-1. Resource Block Parameters

Number	Parameter	Description
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.
