View of the Alarm and Event Screen
Open the alert or the event panel through the System Management -> Diagnostics tab:
Click the Alert or Event panel button. The alert or event panel is opened with the default configuration. The alert and event panels can also be opened simultaneously. The following figure shows the alert and event panel with a specific configuration in the split mode. This configuration shows alert and event tables simultaneously.
The lowest part of the alert and event panel is intended for displaying and changing settings:
This area includes two tabs. The current displayed values/properties for a query are shown behind one tab (for the upper and lower table, respectively). Depending on the table focus, the right tab can be active as well.
All relevant information of a query in compressed form is shown behind these tabs. Furthermore, you can start and stop a query for the specific table with the two buttons at the bottom. The mode is reflected also in the tab heading as - Running, Current, Stopped. You can acknowledge all visible alerts and open the properties panel for changing the query parameters through this panel.
In the left text field, you can see the number of alerts as well as the number of unacknowledged alerts. The first number represents the number of alerts and the second the number of unacknowledged alerts.
The second tab is visible or invisible depending on the configuration. In the standard view, the second tab is used for events with the same functionality as the first tab.
Saves the content of the alert and event tables. The settings are saved in <proj_path>/data.
Prints the table
Starts the query of the alerts or events (what query is started depends on the selected table). If the connection between two distributed system is, a new server was added or the DIST Manager has been stopped, then the play button in the alert and event panel is displayed with a blue border. Thereby the user knows that the data shown is possibly not up-to-date and the view in the table should be updated (by a click on the play button).
Stops the query.
Use the button to scroll backward in time. The button is only displayed in the closed mode.
Use the button to scroll forward in time. The button is only displayed in the closed mode.
This button is displayed only if your query is explicitly connected to other systems or the "All available systems" check box in the "Filter system" tab of the property panel is activated. The button shows connection information for the different systems. The numbers of connections to the systems are given in the text field. The first number represents the number of the actual connections and is followed by the number of the configured connections. The asterisk indicates that you allow connection to all available systems.
A click on the "..." button opens the connection information panel:
The property panel (see button below) allows configuring relevant changes in the view at runtime. You can specify what query is started, what mode is active and what filter settings should be used. You can also set, for example, the table inactive, specify the types of the data point elements for the upper and lower table. For detailed information about the property panel, see the chapter properties of the alert panel.
Opens the property panel (see properties of the alert panel) for configuring queries in the alert and event panel. This panel looks differently for alerts and events. This panel allows specifying new content (what data should be queried).
The content of a newly created configuration is specified in its own panel. The panel AES table configuration (see table configuration) opens through the AES settings button behind the Settings tab of the System Management. Through the table configuration, you define what the alert and event tables should look like, for example, what columns should be displayed.
The available configurations (the default configurations as well as the configurations created via the AES table configuration panel) can be selected from the AES Config. combo box. There are four configured configurations for the view of the alert and event panel by default (these cannot be edited or even deleted):
- aes_default: Shows the alert and event panel in split mode (see figure "Alert and Event panel").
- aes_alerts: Shows only the alert table in full screen mode (events are deactivated).
- aes_events: Shows only the event table in full screen mode (alerts are deactivated).
- aes_command: Commands from a visualization and control system are generally transferred to the periphery. For this purpose, own command data points are used (see chapter state signal simulation). This configuration shows all command data point groups with users.
To change the view of the alert and event panel, select a configuration from the combo box.
Close the alert and event panel by means of the close button. The OnlineHelp button is located next to the Close button.

The AEScreen recognizes the overload. A warning is displayed in the AEScreen. The AEScreen is stopped automatically. AEScreen does not display any new values until the overload has passed. Therefore, there are two timeouts: MINCB_TIME (hardcoded = 2 sec) and MAXCB_TIME (hardcoded = 5 sec). This means that the AEScreen is stopped for a minimum of two and a maximum of five seconds. The AEScreen is restarted after MAXCB_TIME. If the AEScreen is overloaded and the buffer limit (maxBcmBufferSize) has been exceeded, the Event Manager automatically closes the connection to the VISION and the VISION is stopped:
