Microcontroller based Ethernet Interface

Abstract

Ethernet’s combination of low cost, wide spread availability and market familiarity has been attractive to industrial automation applications. In this thesis, Ethernet technology has been reviewed for industrial purposes. An application has been developed to control a remote motor through the network. To make the motor network capable, an Ethernet interface has been added to a microcontroller; the microcontroller is used to drive the Ethernet interface and on the other side used to actuate the motor. In industrial systems real time communication must be provided, so that UDP is used instead of TCP because UDP does not have to establish a formal connection and as a result is a faster way to send a message.
