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

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.
