TPS System Overview

Honeywell Inc.

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.

• Log-in/log-out
