Abstract
In this paper, we implemented universal controller for distributed intelligent control system using LonWorks technology of Echelon co. and developed LON system.


LON is a important element in low-level control network that issues in the automatic as well as in economic aspect.


It can change large control system to small by using distributed control technique with intelligent device. Developed system is based on network communication technique using LonWorks technology.


LonWorks communication module has the advantage that field bus is connected without protocol modification.


LonWorks communication module can be divided hardware module and software module. First, hardware module is divided into microcontroller attaching sensors and hardware communication module for working together control network and data network. Second, software module is realized with neuron C.


Hardware module is making use of neuron chip(TMPN3120FE3M), microcontroller(PIC16F873), transceiver(FTT-10A), Lon card(PCLTA- 20 PCI LonTalk adapter). And operating software is realized with neuron C using NodeBulider 3.0 development tool.


Produced and implemented LonWorks communication module is pretested using LTM-10A, Gizmo 4 I/O board, parallel I/O Interface. For field test, microcontroller module part is tested by hyper-terminal, communication procedure in data network is certified by transmitting and receiving short message using LonMaker for Windows tool.


This thesis is composed of five chapters. Chapter 1 describes the historical background, goals of LonWorks and outline of remaining chapters. Chapter 2 describes the concepts of LonWorks. Chapter 3 describes design and implementation of LonWorks communication module for microcontroller control. Chapter 4 describes the experimental result of LonWorks communication module and consideration to the result. Chapter 5 summarizes all results obtained in this thesis and includes the further reseach topics and the work to be supplemented.
