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.
I
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.
