3. PROFIBUS operating mode
The PROFIBUS operating mode determines the participants for the
bus system. We distinguish between two operating modes:
• pure PROFIBUS-DP operation
• mixed operation of PROFIBUS-DP and PROFIBUS-FMS
In the following, criteria for the selection of the suitable operating
mode are listed.
Criteria Code
numbers Mixed operation
(FS = factory setting) DP operation
(FS = factory setting)
PROFIBUS-DP master
exists − possible necessary
PROFIBUS-FMS master
exists − possible no
Station address can be set L-C1901 yes
FS = 126 yes
FS = 126
Station address can be set
via bus − no yes
Baud rate up to 1.5MBaud L-C1902 yes
FS = 500 kBaud yes
FS = 500 kBaud
Automatic baud rate
setting L-C1903 no possible
FS = active
DP parameter setting
channel L-C1905 possible
FS = active possible
FS = active
Data transmission time /
cycle time − medium low
The PROFIBUS operating mode is selected under L-C1900.
L-C1900 PROFIBUS
operating
mode -0- DP operating mode. Only pure PROFIBUS-DP
-1- Mixed operation. PROFIBUS-FMS and PROFIBUS-
DP services are possible at the same time
The selection of the operating mode causes other bus parameters
to be set automatically to the default values of this operating mode
so that, especially for the DP operating mode, further setttings are
not required.
