Topology
ARCNET is one of the few networks that can be operated in every conceivable
topology. Options include bus, star, or tree topologies, or mixtures of these. This
means that ARCNET can be used for a broad field of different applications.
Bus assignments
ARCNET operates on the token-passing procedure, where each subscriber has
equal rights.
Configuration mechanisms
ARCNET allows to add and to remove subscribers from the network during
runtime. When a new
subscriber is added, the entire network will be re-configured.
Security mechanisms
A 16-bit CRC is appended to every data packet, and checked by the recipient.
If the token is lost, a reconfiguration routine will be initiated, and the network will
automatically be restructured. Additionally, diagnostic registers are available.
Physical characteristics
ABB recommends coaxial cables as transmission medium, for direct connection
to the CPU. But also twisted-pair cables or (glass, plastic) fiber-optic cables can
be connected via bus converters. The line lengths that can be achieved without
any intermediate amplifiers depend not only on the used medium, but also on the
selected baud rate and the number of subscribers. The ranges per segment vary
from approximate ly 120 m for a simple two-wire bus, up to 3 km for fiber-optics,
in each case at 2.5 MBit/s. By providing appropriate hubs, different topologies
and transmis sion media can be combined with each other and the transmission
distance can be increased. The coaxial cables used are a type with 93 Ohm, e.g.
RG 62.
