display individually by address. The default format is standard. The
data and time is also set here.

Category

The Category option is used to assign categories to messages. This
helps in organizing messages for certain operations and when
performing a find.

Message Priorities

The Priority option is used to give messages a priority of low,
medium, and high. As an example, a normal operating water
temperature reading of a generator is a low priority message. A
pre-alarm message of high water temperature is a medium priority
message. An alarm message of high water temperature shutdown is a
high priority message.

In our example, the water temperature is part of the generator signals
that are constantly being monitored and displayed as low priority
signals in the message queue (the message queue can hold up to 64
messages). When the water temperature rises above a pre-alarm
threshold, the medium priority high water temperature message is
added to the message queue. When this happens, only medium
priority messages are displayed. If other medium priority messages
were added to the queue, they are also displayed until a high priority
message is added to the queue. When the water temperature rises
above an alarm threshold, the high priority high water temperature
shutdown messages are displayed.

In order to view the low priority messages, the medium and high
priority messages need to be removed from the message queue.

See InView Protocol, Chapter 4, for information on how to add or
remove messages from the message queue.
