Functions of binary inputs
Figure 8-43 Binary inputs function
Six floating binary inputs are included in the standard equipment ("0" = 0 V [0 to 4.5 V]; "1" =
24 V [13 to 33 V]).
If these six inputs are insufficient, you can add eight more binary inputs through
supplementary electronics (option board).
If you activate the "NAMUR" ("■") operating mode with softkey 1, the binary inputs behave as
marked with "N" in table "Control functions of the binary inputs".
If you deactivate the
"NAMUR" ("□") operating mode, the binary inputs behave compatibly
with the software releases of the older version V 4.3.0 (marked with "X" in table "Control
functions of the binary inputs").
Select softkey 2. The following function screen appears on the display.
Figure 8-44 Defining binary inputs
Here you assign one of the control functions listed below to each input as you like, whereby
every function may only be assigned once.
The connection assignments for the individual inputs can be found in the section "Electrical
connection".
