Profibus DP: Overview and installation
To connect to the Profibus DP, the Profibus module must be integrated in the SIPORT 2.
In the
Digi.interf.
\
General
menu, the
Module type
must be set to
Profibus DP
and
the
Module location
to
SIPORT 2
.
To be able to work with the Profibus, the bus parameters in the
Digi. interf.
\
Profibus
menu must be set correctly. If the associated parameters are changed, the function
becomes effective only after a restart.
If the photometer is used as a terminal device, DIL switch S2/1 must be switched ON on
the connection module (Figure 13, pos. 3).
The addressing of the Profibus DP interface is described in Section 8.7.
