Full Description


Specifies the requirements for fieldbus component parts. It also specifies the media and
network configuration
requirements necessary to ensure agreed levels of data integrity before data link layer
error checking and interoperability between
devices at the physical layer. The fieldbus physical layer conforms to layer 1 of the
OSI 7-layer model as defined by ISO 7498 with the
exception that frame delimiters are in the physical layer.

A fieldbus is a digital, serial, multidrop data bus for communication with low level
industrial control and instrumentation devices such as transducers, actuators, and
local controllers. The Physical Layer here specified provides for transparent transmission
of data units between Data Link Layer entities across physical connections. This document
is Part 2 of a set of eight, which together provide a complete fieldbus standard.
