Note :
When deleting a group, all information definitions within this group will be deleted.
To delete individual entries, click on ,QIRUPDWLRQ in the line with the entry to be
deleted. Then press the right mouse button to open the context menu, and select
'HOHWH ,QIRUPDWLRQ. The remaining steps are the same as those for deleting a
group.
The actual assignment between the information (rows) and the sources and
destinations (columns) of the information is made in the cell of intersection. You click
into the cell and press the right mouse button. A pull down menu appears where you
may determine the properties of the assignment.
In certain cases, the pull down menu will offer ; (allocated) or B (not allocated) as the
configuration choices. In other cases, three options will be offered (e.g. / = latched, 8
= unlatched, and B = not allocated). Entries resulting in an implausible configuration
are blocked and inaccessible to the user.
Single point indications, double point indications, transformer tap indications and
pulse metered values can all be configured as binary inputs. In addition, whether or
not binary inputs are activated by the presence of control voltage can be established.
That is,
• "H" (High with voltage active): Control voltage at the binary input terminals activates
the indication;
• "/" (Low with voltage active): Control voltage at the binary input terminals
deactivates the indication.
