PlantWeb™ Alarms	The alarms and recommended actions should be used in conjunction with
	Section 2: Troubleshooting.
	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.
	NOTE
	PlantWeb alerts for ADB and mass flow cannot be simulated.
	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.	Memory Failure
	2.	NV Memory Failure
	3.	Primary Value Failure
	4.	Secondary Value Failure
	5.	Sensor Module Memory Failure
	6.	Sensor Module 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, see “Alarm Priority” on page 3-15. The default is 0 and the recommended value are 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 hard coded within the device and is not user configurable.

FAILED_ALM

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