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.
