Alarm table

The element ‘Alarm table’ is used to visualize alarms, which must be defined before, see Alarm configuration, Overview.

As soon as the element gets inserted in the visualization object, the dialog ‘Configure alarm table’.  Besides the known categories for configuration of tooltip and security the following settings concerning display and selection in the table can be made.

Category Alarm table

Define what you want to get displayed in the alarm table:

• Change alarm group: Press this button to get the selection tree of the alarm configuration, which offers all alarm groups currently defined. Choose the desired group (which even may contain just one alarm).

  Note: The name of the alarm group, as it is displayed here (e.g. “System/Alarmgroup1”) can be used as PREFIX in a XML-file for dynamic texts in order to get dynamic language switching for the message texts in the alarm table; the associated ID in this must be the number of that line in the Alarm group configuration table, that defines the respective message text.

• Priority: Define the priority for which you want to get displayed all alarms. Permissible range: 0 to 255.

• Alarm classes: Mark a class which you want to get displayed and press button Add to add the class to the list in the window ‘Alarm classes’. Do this for all required classes. In order to remove a marked entry from the alarm classes window press button Delete.

• Activate options Column heading resp. Row heading, if the headings should be displayed in the alarm table.

Category Settings for sorting

Define here according to which criteria the alarm table should be sorted:

• Sort column: Sorting according to Priority, Alarm class, Date/Time or Alarm state

• Sort order: Ascending or Descending;

  Example: Ascending  according to priority means that the table will start with alarms of priority 0 (if available), followed by higher numbered priorities.

Note

When using in a Target-Visualization this settings are not regarded in the display of the alarm history. There the sorting always is descending according to the date.

Category Columns

Define here, which of the columns (alarm parameters) should be displayed in the alarm table: The parameters are defined – except for date and time (alarm is coming) and alarm state in the configuration of the alarm groups: Bitmap, Date, Time, Expression, Value, Message, Priority, Type, Class, State, Target value (for alarm types DEV+ and DEV-), Deadband.

Using the buttons “>”, “>>”, you can take single resp. all parameters from the left to the right window. The selection defined in the right window will be displayed in the alarm table. Using the buttons “<” resp. “<<” entries can be removed from the selection.

For each column you can open the dialog ‘Configure columns’ by a double-click on the entry in the right window. In this dialog Column header and  Column width can be defined.

Category Selection settings \ for alarm table

Define here some settings for the display for the chosen table fields:

• Selection color: This button opens the standard dialog or a target-specific selection list for choosing a color. Define the color in which selected fields should be displayed.

• Row height: Height of the table rows in Pixel.

• Slider size: Height of the slider (Pixel) at the bottom of the table.

• Frame around selected rows: If this option is activated, selected table rows will get a frame.

• Show statusline: If this option is activated, below the alarm table a status bar will be displayed providing the following buttons for the operation in online mode:

  • Acknowledge: All alarm entries marked in the alarm table get acknowledged.

  • Acknowledge all: All alarm entries listed in the alarm table get acknowledged.

  • History: If this button is pressed, instead of the current status of the alarms the table will show a complete list of all events which have occurred up to now (all transitions between any alarm stati). In this list no acknowledgement is possible ! Any new events will be added currently.

    If you have defined a record file, also there you will find this history for all alarm classes, for which the action ‘Save’ has been activated.

  • Start: cancels Stop (see below)

  • Stop: the current update of the list with newly occurring events will be stopped until it is restarted by pressing button ‘Start’.

• Acknowledge variables: This option is only available as long as you have not chosen option ‘Show statusline’ (see above). If it is activated, the functions described above for the status string buttons can get controlled by variables. In order to define these variables, choose a function from the selection list and enter a project variable in the assigned edit field. Thus for example the acknowledgement of all alarms in online mode can be done by a rising edge of the assigned variable.

Note

The Web-Visualization might be configured in a way, that in online mode a tooltip will display the full string of a text entry, which is only partially visible in the alarm table.
