5.4 Bus cable length
5.4.1 Total cable length
The total cable length is also specified by the baud rate.
5.4.2 Segment cable length
Repeaters divide the total cable length into segments. The segment cable length is defined by the
cable cross-section and the number of nodes per segment. Without a repeater, the segment cable
length corresponds to the total cable length.

Note!
• It is absolutely necessary to comply with the permissible cable lengths.
• Observe the reduction of the total cable length due to the signal delay of the repeater.
 Use of repeaters ( 23)
• If the total cable lengths of the nodes are different at the same baud rate, the smaller
value must be used to determine the max. cable length.
