Displaying Messages

Display Event and alarm messages are always output to the display at message level
and are displayed according to display and message priorities.
Display priorities
System messages always have top priority in so far as display is concerned;
unacknowledged alarm messages always have the second highest priority.
Otherwise, messages are displayed in different sequences depending on
whether separate or together output of event and alarm messages was config-
ured.
Message priorities Message priorities of 1 (low) to 4 (high) can be set within event and alarm
messages in the configuration according to their importance. If several mes-
sages of the same display priority exist simultaneously, they are displayed
according to their message priorities, those with the highest message priority
being shown first and those with the lowest last.
Displaying If several messages having identical display and message priorities exist si-
first/last message
multaneously, the most recent is displayed in all cases, for both event and
alarm messages.
Depending on the value preset during configuration, the oldest message or
the most recent message is shown for alarm messages. You can use the stan-
dard screen to modify the setting for viewing the oldest (first) or most recent
(last) alarm message when there are several of them waiting. To do this,
choose System
7-6
DispMsg and set the corresponding parameter.
