The classic AS-i bus is designed for a cable length of 100 metres.
Experienced users have found out that often systems with 130 meters and more function without any problems. However, AS-i has a free topology so that there is no general installation rule for these 100 plus "x" metres.
In many cases long, non-terminated cables cause reflections which overlay the AS-i messages and cause faults and message repetitions.
