Plugging the bus connector into the module
Connecting bus connector
Proceed as follows to connect the bus connector:
1. Plug the bus connector into the module.
2. Screw the bus connector tightly onto the module.
3. If the bus connector is at the beginning or end of a segment, you must activate
the terminating resistor (switch position “ON”) (see Fig. 7-2).
Make sure that the stations where the terminating resistor is activated are always
supplied with voltage when they are ramping up and during operation.

Unplugging bus connector
You can unplug the bus connector with the looped through bus cable from the
PROFIBUS DP interface at any time, without interrupting the data traffic on the
bus.
!
Warning
Disruption of data traffic on the bus possible!
A bus segment must always be terminated by the terminating resistor at both
ends. This is not the case if the last node with the bus connector is de-energized.
Because the bus connector takes its voltage from the station, the terminating re-
sistor does not have any effect.
Make sure that the stations where the terminating resistor is switched on are al-
ways supplied with voltage.
