If the same value is used by multiple applications or is also historized, this usage
could significantly reduce the load on the TPN as compared to direct accesses to
the TPN Server.

PHD Auxiliary Tags are used to store the state of the application, which is useful
for communication with other applications or for operator access through GUS.
This is an alternative to storing the data on the TPN (for example, in AM custom
data segments), which, again, yields significantly reduced TPN loading.
Event Annunciation and Journal Entries
TPS Network Process Alarms and Messages
Process alarms and messages from the TPS Network are presented on the Native
Window and the Integrated Keyboard (IKB) exactly as they are on the TPS Network.
In addition TPS Network alarms and messages are available within GUS displays as
discussed in the previous section on GUS.
TPS Network System Status
TPS Network System status (including LCN, UCN, Data Hiway, module, and box
status) is presented on the Native Window and the Integrated Keyboard exactly as they
are on the TPN. For system level operations, such as directing node startups,
checkpointing, etc., the operator must use the Native Window.
Journals of TPS Network Events
HM Journals are available exactly as they are on the TPN, including data retrieval
through the Native Window. In addition, PHD can be configured to collect HM
journals and store them into relational tables, where the information is available
through various relational query tools.
Application Alarms
NT applications that need to present application conditions such as process alarms to
the operator can use AM facilities (e.g., switch data point) to create custom alarms.
NT Event Log
Other events of interest are captured in the NT Event Log, on each TPS node. They are
viewed through NT facilities at the node of origination of the event. These events
include such things as the following.
