Matrix

The matrix columns are divided into three types: Information, Source, and Destination.
To the left of the matrix, information is divided into information groups.
The matrix may become very extensive because of the amount of information
contained within. Therefore, it is useful to limit the display via filtering to certain
information, thus reducing the number of rows.
The tool-bar below the menu bar contains two pull-down menus by which information
may be filtered. Using the first menu, the rows can be limited to indications,
commands, indications and commands, or measured and metered values. The
second menu allows to display only configured information, information configured to
physical inputs and outputs, or non-configured information.
A further reduction in the number of rows is possible, by compressing an information
group to one row. This is done by double-clicking on the group label area (located to
the far left). If this is done, the number of rows is reduced, allowing the user to focus
on the information groups of interest. A second double-click restores all rows in the
information group.
To limit the width of the matrix, two possibilities exist: The tool bar allows to switch
between standard view and short view, or individual columns can be hidden.
In the latter case you double-click on the field with the column heading thus hiding the
contents of the associated column. In the example of Figure 5-4, the long text (/)
under IQIRUPDWLRQ is not shown. By double-clicking on long text field (/), the long
text becomes visible again, and vice versa.
With two options on the tool bar you may switch between standard view and short
view, thus modifying the all columns under the 6RXUFH and 'HVWLQDWLRQ title
blocks. The columns associated with the ,QIRUPDWLRQ block remain unchanged.
In standard view, all binary inputs, binary outputs, and LEDs are accessible, as shown
in Figure 5-4 for the binary outputs and LEDs.
In short view (not illustrated in the figure), a common column is displayed for each of
the sources and destinations. Within the individual cells of a common column,
information regarding the configuration type is available in an abbreviated form. For
example, the abbreviation H1 in a cell of the common binary input (BI) column means
that the corresponding information is configured with active voltage (High) to binary
input 1. If an information is assigned to several sources or destinations, the
abbreviations of all destinations are shown, separated by commas. If there is not
enough space in the cell for the simultaneous display of all abbreviations, a double-
click on the cell and movement of the text cursor within the cell allows to scroll through
the entire contents of the cell.
To switch between standard view and short view, the menu item 9LHZ can also be
used.
All information is organized into information groups. In addition to general relay
information, information regarding individual device functions is also included.
By clicking on an information group title area with the right mouse button, a context
menu can be viewed, which contains information regarding the properties of that
information group. This is particularly useful if the information group is associated with
a function that contains parameter settings.
If the information group belongs to a protective function for the relay, a dialogue
window can be accessed in which the settings of the protective function may be read
out and modified. The procedure for entering settings of a protective function is
