PROFIBUS Overview

Introduction

PROFIBUS (Process Field Bus) is a standard for field bus communication in automation technology and was first

promoted in 1989 by BMBF (German department of education and research).

Topology

PROFIBUS uses the bus topology. In this topology, a central line, or bus, is wired throughout the system.

Devices are attached to this central bus. One bus eliminates the need for a full-length line going from the

central controller to each individual device.

In the past, each PROFIBUS device had to connect directly to the central bus. Technological advancements,

however, have made it possible for a new “two-wire” system. In this way, multiple PROFIBUS buses can

connect to each other.
