BC-600-PB Connection to PROFIBUS
Softing Page 17
7.1.2 Connection types
There are several ways to connect a bus station to a PROFIBUS network:
•
Using connectors
o
D-sub connectors, most of which have an integrated terminating
resistor and, optionally, an additional service socket
o
M12 connectors for environments requiring increased IP ratings
o
Special vendor-specific hybrid connectors; they are used in
combination with special cables to supply power via the bus
•
Using terminals for direct connection
Due to the typical daisy-chain topology, the connection points of the bus
stations are the only possible points for connecting the test tool in most cases.
7.1.3 Adapter cable
The PROFIBUS Tester 4 is supplied with the D-sub adapter cable BC-600-PB-
CB-DSUB-2 „Standard“ (light connector). For testing on live systems the
optional D-sub adapter cable BC-600-PB-CB-DSUB-2 is recommended. An
M12 adapter set is optionally available, see on page
9 .
Attention: Use only the short original cables with special pin layout to
connect the unit to a PROFIBUS network. Do not cascade more than
two D-sub connectors with service sockets at the same time:

Active connection cables with integrated repeaters, such as Softing's BC-131-
PB, cannot be used for testing.
