CHAPTER 8
Alarms
This chapter describes CX-Supervisor alarms and the procedures associated with the creation,
amendment and removal of alarms using the Alarm Editing facility. The use of alarms during the
running of a project is also described.
What is an Alarm?
Alarms provide notification of a problem during the execution of an application in runtime. Alarms
are defined in the development environment and monitored in the runtime environment. Alarms
range from incidental to catastrophic in nature.
In runtime, the occurrence of an alarm condition, and any subsequent change of state, is recorded in a
log file known as the Alarm History log.
An operator is alerted to an alarm condition by means of an Alarm Acknowledge dialog, which may
also be accompanied by a warning sound. A list of current alarms is also maintained.
Individual alarms are defined in the development environment using the Alarm Editor. General
alarm settings are controlled in the development environment using the Alarm Settings dialog.
The Alarm Object (refer to chapter 4, Objects) is a graphical object which can be configured to
display alarm messages for certain groups of alarms and thus provides a convenient way of filtering
alarm messages.
Alarm definitions are made and modified using the Alarm Editor. To use the Alarm Editor, CX-
Supervisor must currently have a project open. If no project is currently open, either select Open
Project from the Project menu to open a previously saved project, or select New Project from the
Project menu to create a new project.
Facilities exist to add an alarm, modify an existing alarm, copy an alarm, remove an existing alarm
following confirmation, and display the alarm list in name, type or description order.
Alarm Settings
To open the Alarm Settings dialog, select the Change General Alarm Settings button from
the Alarm Editor toolbar. The dialog is displayed as follows.
