Alarm and event messages can be configured so that text components flash in
order to distinguish them from other message texts.
Messages may contain text and tag fields. Tag fields display current PLC ac-
tual values in numeric form.
A sub–category of the event message is the standby message. The standby
message is the event message number 0. It is displayed when there are no event
messages on the Touch Panel.
A current event or alarm message can be displayed in either a message line or
message window. One of the following combinations can be defined in the
configuration:
S Window/window
Event messages and alarm mes-
sages are displayed in separate
windows.
The alarm message window is
opened automatically when an
alarm message arrives. When the
alarm message is acknowledged,
the alarm message window disap-
pears.
The event message window can
be opened only by activating a
button.
