PlantWeb™ Alarms	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.
	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.	Electronics Failure
	2.	NV Memory Failure
	3.	No I/O Power
	4.	Primary Value Failure
	5.	Secondary Value 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. The default is 0 and the recommended value is 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 not user configurable.

FAILED_ALM

Alarm indicating a failure within a device which makes the device non-operational.
