5.2.5 Performing Configuration
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 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.
Configuring Binary
Inputs as Sources Single point indications, double point 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 deacti-
vates the indication.
Note :
When deleting a group, all information definitions within this group will be deleted.
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.
