Bus cable length
The length of the bus cable depends on the baud rate used:
Baud rate [kbps] Length [m]
9.6 ... 93.75 1200
187.5 1000
500 400
1500 200
3000 ... 12000 100
Note!
The baud rate depending on the data volume, cycle time, and number of nodes
should only be selected as high as required for the application.
Tip!
For high baud rates we recommend to consider the use of optical fibres.
Advantages of optical fibres:
ƒ On the transmission path external electromagnetic interference remains
ineffective.
ƒ Bus lengths of several kilometres are also possible with higher baud rates.
The bus length
– is irrespective of the baud rate.
– depends on the optical fibre used.
