Confirmation window before deleting a user defined group
Click Yes if you actually want to delete the group.
Note:
When deleting a group, all information definitions within this group will be deleted.
To delete individual entries, click under Information in the line with the entry to be
deleted. Then press the right mouse button to open the context menu, and select De-
lete Information. The remaining steps are the same as those for deleting a
group.
The actual assignment between the information (rows) and the sources and destina-
tions (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 de-
termine the properties of the assignment. In certain cases, the pull down menu will of-
fer X (allocated) or _ (not allocated) as the configuration choices. In other cases, three
options will be offered (e.g. L = latched, U = unlatched, and _ = 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;
• "L" (Low with voltage active): Control voltage at the binary input terminals deacti-
vates the indication.
Note:
A single logical indication should not be configured to two binary inputs, since an OR-
combination of both signals is not ensured. The operating program allows only one
combination, and deletes the first combination when a second is established.
