Alarm Priority

ADVISE_ACTIVE

The ADVISE_ACTIVE parameter displays which of the advisories is active. Only the advisory with the highest priority will be displayed. This priority is not the same as the ADVISE_PRI parameter described above. This priority is hard coded within the device and is not user configurable.

ADVISE_ALM

ADVISE_ALM is an alarm indicating advisory alarms. These conditions do not have a direct impact on the process or device integrity.

Alarms are grouped into five levels of priority:

Priority	Priority Description
Number

0The alarm condition is not used.

1An alarm condition with a priority of 1 is recognized by the system, but is not reported to the operator.

2An alarm condition with a priority of 2 is reported to the operator.

3-7	Alarm conditions of priority 3 to 7 are advisory alarms of increasing priority.
8-15	Alarm conditions of priority 8 to 15 are critical alarms of increasing priority.

Process Alarms

Recommended Actions for PlantWeb Alerts

Process Alarm detection is based on the OUT value. Configure the alarm limits of the following standard alarms:

•High (HI_LIM)

•High high (HI_HI_LIM)

•Low (LO_LIM)

•Low low (LO_LO_LIM)

To avoid alarm chattering when the variable is oscillating around the alarm limit, an alarm hysteresis in percent of the PV span can be set using the ALARM_HYS parameter. The priority of each alarm is set in the following parameters:

•HI_PRI

•HI_HI_PRI

•LO_PRI

•LO_LO_PRI

RECOMMENDED_ACTION

The RECOMMENDED_ACTION parameter displays a text string that will give a recommended course of action to take based on which type and which specific event of the PlantWeb alerts are active.
