3. Compare both values.
If the value given in Tab. 2 is smaller than the total cable length given in Tab. 1, repeaters
must be used. Repeaters divide the total cable length into segments.

Note!
Note the reduction of the total cable length due to the signal delay of the
ƒ
repeater (see example
Mixed operation
ƒ
– Mixed operation is available if different nodes are operated on the same
mains.
– If the total cable lengths of the participants are different at the same
baud rate, the smaller value must be used in order to determine the
max. cable length.
Example: Selection help
Given:
Cable cross-section:
Number of nodes:
Repeater:
At maximum number of nodes (63) the following cable lengths/number of repeaters must
be complied with:
Baud rate [kbps]
Max. cable length [m]
Segment cable length [m]
Number of repeaters
Check repeater application
Given:
