The following table describes the typical alert types and colors.
Depending on your system configuration, other principles and colors may be
used. The following presents only some typical examples.
CAUTION!
Table 9 Alarm Types
Type Frame Color Description
Alarm Red When an alarm is raised the frame is blinking.
After acknowledgement the red frame remains, but blinking stops. Alarm
frame disappears only when the alarm reason vanishes.
Warning Orange When a warning is raised the frame is orange, but it is not blinking.
Acknowledgement makes the color disappear.
Notification Green When a notification is raised the frame is colored, but it is not blinking.
Acknowledgement makes the color disappear.
If different types of alerts are linked to the same data field alert frame then only the most
severe alert is shown. Alarm overrides warning and notification, warning overrides
notification.
Depending on the system configuration, the alerts can be automatically acknowledged or an
ACK button is included for acknowledging them. Depending on system configuration and
the notification type, the acknowledging will, for example, stop the flashing.
Alarms, warnings, and notifications may be emphasized with audio sounds. The possible
sound configuration settings are: the type of sound, the continuation of the sound, and the
acknowledging logic.

The data fields can also contain tendency indicators indicating whether the value has been
recently increasing, decreasing or has not changed.
