Connecting to PROFIBUS-DP

Baud Rate
The module uses single modular width.
The RM2-DP is connected to the PROFIBUS by means of a male DB-9 con-
nector which, for security reasons, should be screwed tightly onto the female
DB-9 connector of the RM2-DP12. The X71 PROFIBUS connector is located
on the front panel. The pin assignment corresponds to the PROFIBUS stan-
dard.

From the P5V_ISO on the X71 PROFIBUS-DP connector, up to 100 mA of
current can be picked off externally.
The module automatically adjusts to the baud rate of the PROFIBUS-DP
(9600 baud to 12 Mbaud).
