Defining alarm areas

With the button the violated class is indicated along with the number of violated alarms/unacknowledged alarms in the class.

There are three ways to create an alarm area:

Mouse click on the according icon in the tool bar
Command Alarm area new in the context menu
Click button Paste

Configuration and management of the alarm areas is done via the respective properties. Configurable settings of an alarm area are:

Property	Description
Name	Name of the alarm area.
Status variable	The first bit of this byte variable shows whether there are any active alarms in this alarm area. The second bit of this byte variable shows whether there are any unacknowledged alarms in this alarm area. Button `...` opens the dialog for variable selection.
Number of active alarms	Variable that contains the number of active alarms in this alarm area as a numerical value. Button `...` opens the dialog for variable selection.
Number of unacknowledged alarms	Variable that contains the number of unacknowledged alarms in this alarm area as a numerical value. Button `...` opens the dialog for variable selection.
Nr.	Number of the alarm area, as specified by the system.

Here you create a list of alarm areas. Each alarm area contains a list of alarm classes. 3 variables can be linked to each alarm class.

Alarm area	Class	Status variable	Count variable active alarms	Count variable unacknowledged alarms
1	Warning	Status_warn_1	Active_warn_1	Unackn_warn_1
	Disturbance	Status_error_1	Active_error_1	Unackn_error_1
2	Warning	Status_warn_2	Active_warn_2	Unackn_warn_2
	Error	Status_error_2	Active_error_2	Unackn_error_2

Three variables can be linked to each combination alarm area/alarm class.

Status variable (BYTE), which specifies with a bit pattern, whether alarms are active or unacknowledged:

Bit	Meaning
0	1=active alarms 0=no active alarms
1	1=unacknowledged alarms 0=no unacknowledged alarms

Number of active alarms (INT or similar)

Number of unacknowledged alarms (INT or similar)

Attention

For an alarm to be displayed in the selected alarm area, edit the properties of the corresponding variable. Select the corresponding alarm area and alarm treatment.
