5.4.3 Use of repeaters

Compare the values from the tables Total cable length ( 22) and Segment cable length ( 22).

If the detected segment cable length is smaller than the total cable length to be achieved, repeaters

must be used.

Example: Detecting cable lengths / number of repeaters

At the maximum number of nodes (127), the following cable lengths/number of repeaters from the

specifications have to be observed:

Given:

Cable cross-section 0.5 mm

, according to Bus cable specification ( 21)

Number of nodes 127
