PlantWebAlarms

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.
