5.3 PROFIBUS interface (X22 on SLE-DP)
The interface between the SLE-DP and the PROFIBUS line is the
EN 50170-compliant 9-pin SUB D socket with screw locking
mechanism (UNC) on the front of the housing. It is labeled with the
designation X22 as well as "PROFIBUS" and the following symbol:
.
The interface supplies an electrically isolated, short-circuit-proof supply
voltage for the optional connection of an OLP (Optical Link Plug). All
PROFIBUS signals are isolated from the 24 V voltage supply (X1) and
the encoder signals (X21).
The connector hardware for both the encoder interface and the
PROFIBUS interface is a 9-pin SUB D socket. The two interfaces can
be distinguished only by their labeling and position (cf. Fig. 4-3). The
plug and socket must be connected correctly by the end-user during
installation.

The cables must be connected by means of PROFIBUS connectors
since these contain the bus terminating resistors.
