Connecting
4.7 Connecting PROFIBUS/MPI
Removing the bus connector
You can remove the bus connector with a looped-through bus cable from the PROFIBUS DP
interface at any time without interrupting data traffic on the bus.
NOTICE
Data communication disturbed because bus terminator missing
A bus segment must be terminated at both ends with a terminating resistor. This is not the
case if the last bus connector node is de-energized, for example. Because the bus connector
takes its voltage from the station, this terminating resistor is ineffective.
Make sure that the stations at which the terminating resistor is connected are always
energized.
Adapter plug
An adapter plug (Article No. 6FX2003-0BB00) is required when the bus cable has to be looped
through the PROFIBUS interface (X126; two PROFIBUS cables wired to the plug) and also
● Ethernet interface X120, in the case of D4x5‑2 DP or
● PROFINET interface X150 for D4x5‑2 DP/PN Port 3
has to be wired to a FastConnect plug.
When using the adapter plug, the PROFIBUS connector is higher, which creates extra wiring
space.
