4.11.6.1.2 Format<br />

This field shows the last queued alarm. Cursor keys can be used to scroll through alarm entries<br />

in this list. The displayed alarm can be acknowledged.<br />

Defines the length of the alarm line in characters and the font to be used.<br />

4.11.6.1.3 Key Assignment<br />

Determines the keys which are to be used for the corresponding action. These could be either keys from the<br />

operator panel being used (configured as function keys) or buttons/hot spots in the case of panels with touch<br />

screens.<br />

A corresponding function key has to be assigned to each key. Otherwise, otherwise an error message appears<br />

and the dialog box cannot be closed with OK.<br />

The 'Previous Alarm' and 'Next Alarm' keys are only provided for 'Active Alarm' lines. The other alarm line types<br />

only have an 'Acknowledgement' key.<br />

4.11.6.1.4 Additional Settings<br />

Under the 'Colors' tab of the dialog box, colors used for alarm line display can be set or a color control variable<br />

can be connected.<br />

The information displayed in the alarm line and the separators to be used are set under the 'Field Format' tab. A<br />

detailed listing of all settings can be found in the reference manual (see references at the end of this page).<br />

4.11.6.2 Alarm List<br />

Introduction to <strong>Visual</strong> <strong>Components</strong> 2.3<br />

An alarm list displays the same information as an 'Active Alarm' line but displays several lines. Field size can be<br />

selected as desired, but the number of alarms which can be displayed simultaneously depends on the available<br />

display surface and the selected font.<br />

Two keys can be used to scroll thorough the previous (newer) or next (older) alarms in the alarm list. The alarm<br />

with the current cursor focus can be acknowledged with the acknowledgement key. The function keys to be<br />

used must be configured (see below).<br />
