Additional components

The AS-Interface functions without any

problem with standard components up

to a length of 500 m – without re-

peaters or extenders up to 100 m.

… repeaters

When using repeaters, up to two re-

peaters can be connected in series, on

which all components can be distrib-

uted to the segments in any way. But

there is a widespread misunderstand-

ing that an AS-Interface network therefore

has a maximum extent of 300 meters!

Much larger extents are possible because

parallel arrangement of several lines in a

star configuration is possible. In a mail sort-

ing system, an AS-Interface network has a

total extent of 1600 meters. The repeater

works as an amplifier. The slaves can be

connected to all AS-Interface segments.

Each segment requires a separate power

supply unit. In addition, the repeater iso-

lates the two segments, which improves

selectivity in the event of a short-circuit.
