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.

Alarm Priority

Alarms are grouped into five levels of priority:

Process Alarms

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 Actions
for PlantWeb Alerts

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.
