Once all the information has been provided for the new alarm, selecting the OK pushbutton commits
the new alarm to the alarms database, whilst the Cancel pushbutton aborts this add operation.
Note:
Alarm Header Information
The name of the alarm is entered in the Name: field. The alarm name can be constructed of up to 20
alphanumeric characters. Any other characters, including spaces, generate an audible error, or an
Invalid Alarm Name entered message. This field is visible from the Alarm Editor dialog.
The group to which this alarm is added is selected from the Group: field. To create a new group
name, simply type the name of the new group in the Group: field. The use of alarm groups allows
filtering of alarm messages by group name.
The priority assigned to the alarm is selected from the Priority: field.
The Display Alarm Acknowledge Box setting determines whether the Acknowledge Alarm dialog is
displayed in runtime when the alarm occurs. The dialog notifies the operator of the alarm condition
and allows the operator to acknowledge the alarm. The default value is True.
Activating the Auto Acknowledge Alarm setting causes these messages to be acknowledged without
any operator action. Refer to chapter 8, Alarm Acknowledge.
The Play Sound setting determines whether an audible warning is sounded when the alarm occurs.
The default value is False. Note that a waveform file must also have been selected for the warning
sound to be heard. The waveform is selected by using the Alarm Sound pushbutton on the Alarm
Settings dialog.
An alarm description, detailing the possibilities of how the current alarm would be raised, is inserted
in the Description: field. To move to a new line, press <Ctrl>+<Return>. Any characters are valid,
and up to 255 characters may be entered in the text field. This field is visible from the Alarm Editor
dialog.
Activating the Print Alarm Messages setting causes alarms of this type to be printed automatically
when they occur.
Alarm Type
The alarm type can be Simple, Deadband or Rate of Change. Select the desired type by clicking on
the Simple, Deadband or Rate of Change settings. This field is visible from the Alarm Editor dialog.
Release 2.0
The short-cut keyboard combinations for Cut, Copy and Paste operations are valid
within the Add Alarm dialog. Highlight part or all of a field and type <Ctrl>+X to
cut the text or <Ctrl>+C to copy the text. Insert the cursor at the desired field and
type <Ctrl>+V to paste the text. Since the cut and copy operations store the
information in the Windows Clipboard, it may be pasted to another dialog or
application.
