Bus cable length
Depending on the baud rate and the cable type used (thick cable/thin cable), the following
bus cable lengths are possible:
Baud rate [kbps] Bus cable lengths [m]
Thick cable Thin cable
125 500
100 250 250
500 100
If both thick and thin cable types are used, the maximum cable lengths can be defined
according to the baud rates as follows:
Baud rate [kbps] Max. bus cable length
125 500 m = L thick + 5 L thin
250 250 m = L
thick
+ 2.5 L
thin
500 100 m = L
thick
+ L
thin
L
thick
: thick cable length
L thin : thin cable length

Note!
Select a baud rate in dependency of the data volume, cycle time and number
of nodes just high enough to suit your application.
