Industrial "Field Buses" are sub-divided into Buses depending on
the capabilities they offer.
The most complex are the Control
Buses: High Speed Ethernet (HSE) and ControlNet, followed by the
Field
Buses: Foundation Fieldbus and Profibus, the Device Buses:
DeviceNet, Profibus DP, SDS and Interbus-S, and then the Sensor Buses:
CAN, ASI, Seriplex and LonWorks.
Control Buses are listed on this page
Attached Resource Computer NETwork "ARCNET" [ANSI/ATA 878.1-1999]
uses a token-passing protocol, with packet lengths of from 0 to 507 bytes
at a data rate of 2.5 Mbps [10Mbps max].
ARCNET uses CRC-16. Depending on
the topology the following cables may be used: Coax; RG-62/u, RG-59/u
[BNC], or #24 or #22 AWG solid copper twisted-pair cable [RJ-11], or
fiber optic cable [SMA or ST].
ARCNET is also used with [DC or AC
coupled] RS485.
ARCNET Trade Association (ATA)
Developed by Allen Bradley. Uses RG6, around 250 meter @ 5Mbytes over dual redundant BNC connections. Used for Time/Mission Critical applications. Looks to be Ethernet based.
Over-all Description {Synergetic}
Product Listing {ControlNet.org}
High Speed Ethernet or HSE and the "conventional" Ethernet both share the
same physical and MAC levels , but use different protocols.
HSE [High
Speed Ethernet] runs at 100 Mbps over standard Ethernet physical layers.
Uses IEC/ISA-S50.02-1992 as the standard, as does Profibus.
The
physical layer (PHY) for device control is H1 which runs at 31.25kbps on
a single twisted pair wire that can be run up to 1900 Meters, or HSE
[High Speed Ethernet] which runs at 100 Mbps over standard Ethernet physical layers.
FOUNDATION
Fieldbus provides up to 32 devices on a H1 segment running at 31.25 kps
(differential).
H1 is a IEC 61158 standard.

Industrial Ethernet and the "conventional" Ethernet both share the same
physical and MAC levels , but use different protocols.

SafetyBus is based on the CanBus [with added redundancy] as a
multi-master system with a linear bus topology and uses an open protocol.
SafetyBus is event driven, with messages being sent only when an event
changes.
{Industrial Control Bus Index}
WorldFIP "Flux Information Processbus" [European Standard
EN50170].
The Physical Layer: is compliant to IEC 1158-2 for all speeds
[up to 2.5Mbit/sec (typically 1Mbit/sec)] on twisted pair and fiber
optic.
The Physical Layer, Data Link Layer, and Application Layer are
specified.
