Baud rate / length of bus cable
The length of the bus cable depends on the baud rate used:
Baud rate [kbps]
9.6 ... 93.75
187.5
500
1500
3000 ... 12000
)
Note!
The baud rate depending of the data volume, cycle time and number of nodes
should only be selected as high as required for the application.
I
Tip!
For high baud rates we recommend to consider the application of optical
fibres.
Advantages of optical fibres:
Electromagnetic interferences on the transmission path remain ineffective.
ƒ
Bus lengths of several kilometres are also possible with higher baud rates.
ƒ
The bus length is
– independent of the baud rate.
– dependent on the optical fibre used.
