Setting Values
The upper box in the diagram on the left is the
usual symbol of a setting value in a function
diagram. The setting name is speci󰊟ed by its
module and parameter name, separated by a
dot “.” one from the other.
Second example: Thanks to the high degree of
modularization in WI Line protection devices,
the logic depicted in some function diagrams is
often valid for several modules. In these cases,
only a symbolic module name, for example:
“name”, is given. In the heading part of the
diagram, the meaning of “name” is speci󰊟ed as
a list of modules to which the diagram applies.
In rare cases it is necessary to also specify
the menu path (or at least the top-level menu
item), because it would be too inconvenient
to specify this particular setting only based
on module name and parameter name. In the
third example, the setting is marked as a Field
Parameter (i. e. to be found within menu branch
[Field Para]).

Input and Output Signals
A binary (output) signal is shown on top.
A dashed line indicates a measured value (i. e.
an analog signal).
Bottom row left: Numbered input signal; right:
numbered output signal: From the technical
point of view, there is no di󰊞erence to “normal”
(non-numbered) signals. But these signals
appear in several di󰊞erent diagrams, and the
numbering helps to identify and locate them
across the Technical Manual.
Therefore all encircled numbers appearing “on
the right side” (i. e. as an output signal) of a
diagram are listed as part of the Index chapter,
so that you can look up where a particular
signal has been “generated”.
Another remark: All diagrams in this document
show a small label, for example the bottom
one: “HPT_Y46”. This is the diagram name, i. e.
a unique identi󰊟er for the diagram. Of course,
this is not a setting name, nor any other part of
the depicted logic. All function diagrams have
an identi󰊟er with the characters “_Y”.)
