PROFIBUS Connector
The PROFIBUS connector on the font of the Unit is a 9-pin female sub-D con-
nector, as recommended by the PROFIBUS standard EN 50170.
The signal RTS (TTL signal) is for the direction control of repeaters, which do
not have a self-controlling capability.
The signals DGND and VP are used to power the bus terminator located in
the cable connector.
Note The orientation of the sub-D connector allows the use of PROFIBUS connec-
tors with a 90° angle cable outlet, e.g ERNI, Delconec and Phoenix.
Note The 9-pin sub-D connector uses #4/40 UNC thread, for mechanical fixation of
the cable connector. Make sure that if non-standard PROFIBUS connectors
are used, the corresponding thread is used on the cable connector.
