Presentation
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.
Standby message
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
