Click the left mouse button on the status button of the desired signal to open the di-
alog “
Select Binary Input ” for configuring the status of the particular binary input
signal.
The dialog has two tabs, the first of which (“TRUE / FALSE”) provides facility for
setting the input status to “Always True”, OR “Always False”. This is a permanent
assignment, without the involvement of an output signal of another function.

The second tab “Output from Function” enables the output of an existing instance
of a protection function to be connected to the particular signal input.
The “ Output from Function ” tab lists all the protection function instances set for
the particular bay unit together with the unique number of the instance. Upon se-
lecting a protection function in the list on the left by clicking the left mouse button
on it, its binary output signals appear on the right of the dialog.
