A bus segment must always be terminated at both ends with a matching
resistor. This is not the case, for example, if the last slave with bus
connector is not live. Because the bus connector obtains its voltage from
the station, the matching resistor has no effect.
Make sure that the stations at which the matching resistor is connected is
always supplied with voltage.
You can pull out the bus connector with looped-through bus cable from
the PROFIBUS-DP interface at any time without interrupting data transfer
on the bus.
