Alerts processing within the device
1. Diagnostics perform comprehensive checks and update status within the device. These
status conditions allow the user to troubleshoot probable causes and take corrective
actions.
2. The status conditions are then mapped into four status signals that can be used for
annunciation on the segment to the host.
3. Before annunciation, a check is made to determine if the user has masked any alert
parameters. Any masked parameters will not be annunciated to the host, but will be
visible using the device DD or DTM.
4. Unmasked alert conditions are annunciated by the appropriate status signal to the
host.
PlantWeb Alerts and NE107 alerts are both processed using the steps described previously,
and annunciate the same consolidated status parameters.

1. Detailed status includes
conditions found by all
diagnostics the device
runs.
Detailed status for
NE 107 and PlantWeb
alerts are identical.
2. Consolidated status
groups diagnostics by
probable cause and
corrective action.
Consolidated status for
NE 107 and PlantWeb
alerts are identical.
3. Mapping of conditions
defines how conditions will
be reported. NE 107
mapping can be user
modified.
4. Masking of conditions
determines which
conditions are reported to
the host and which are not
by status signal. All
status signals remain
5. Unmasked active
conditions are reported to
the host. The unmasked
