Connection example for the addressing and bus termination
In the following connection example, the input/output module XE 040/x is the
last bus participant and must be configured with an active terminating resistor.
In this case, the terminating resistor of the operating panel must be deactivated
since it is not the last participant (DIP switch 6=OFF).

Cable specification
Cable type: shielded, twisted pair data cables with a characteristic impedance
of 100 - 120
Ω
. The connector casing must be completely conductive. The
cable shielding must connect surface-to-surface with the shield cover of the
plug.
