4.2.5.1 Alert handling
The Tranduscer Block will act as a coordinator/
collector for (PlantWeb
™
) alerts.
Although the alerts have default settings (see table
4.3), these levels can be set by the customer to
match their requirements.
There are three levels of alerts available:
1 Failed Alerts
A Failure Alert 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.
This alert has the following five parameters:
1 FAILED_ENABLE: Enable the indication and
reporting
2 FAILED_MASK : Suppress reporting
3 FAILED_PRI : Designates the priority
4 FAILED_ACTIVE : Displays which of the condi-
tions within the alert is active.
5 FAILED_ALM : To report the particular failed
condition to the host system.
2 Maintenance Alerts
A Maintenance Alert indicates a condition within a
device that, if not attended to in the near future
(the type of alert defines the time period for “Near
Future”) 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 as soon as possible.
This alert has the following five parameters:
1 MAINT_ENABLE : Enable the indication and
reporting
2 MAINT_MASK : Suppress reporting
3 MAINT_PRI : Designates the priority
4 MAINT_ACTIVE : Displays which of the condi-
tions within the alert is active.
5 MAINT_ALM : To report the particular failed
condition to the host system.
3 Advisory Alerts
An Advisory Alert indicates a condition within a
device that is informational in nature. The alert is
used to notify the host that the device has de-
tected a condition within the device that is not
critical, will not cause a failure if left unattended
but should be reported to the host for awareness
and possible action.
This alert has the following five parameters:
1 ADVISE_ENABLE :Enable the indication and
reporting
2 ADVISE_MASK : Suppress reporting
3 ADVISE_PRI : Designates the priority
4 ADVISE_ACTIVE : Displays which of the condi-
tions within the alert is active.

condition to the host system.
