Connector features
The
bus connector is used to connect the PROFIBUS cable to the PROFIBUS DP interfaces.
thus establishing a connection to additional nodes.

4.8.3 Length of PROFIBUS cables
Cable lengths and baud rate
The baud rate determines the cable length of a subnet segment.
Table 4-5 Permitted cable length of a subnet segment for specific baud rates
Baud rate Max. cable length of a segment (in m)
19.6 to 187.5 kbit/s 1000

500 kbit/s 400
1.5 Mbit/s 200
3 to 12 Mbit/s 100
1)
With isolated interface
Longer cable lengths
If you must implement longer cable lengths than permitted in one segment, you must use
RS 485 repeaters. The maximum possible cable lengths between two RS 485 repeaters
correspond to the cable length of a segment. You can connect up to nine RS 485 repeaters
in series.
Note that an RS 485 repeater must be counted as a subnet node when determining the total
number of nodes to be connected, even if it does not have its own PROFIBUS address.
