Figure 5-49 Binary input 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 retrofit additional electronics with eight further
binary inputs (optional board).
If you activate the "NAMUR" ("■") operating mode with softkey 1, the binary inputs behave as
in table "Binary input activation functions" marked with "N".
If you deactivate the "NAMUR" ("□") operating mode, the binary inputs behave compatibly
with the software outputs of the older version V 4.3.0 (in the table "Binary input activation
functions" marked with "X").
Press softkey 2. The following function screen appears on the display.
