An Advanced Implementation of a Distributed Control Scheme Based on LonWorks System over Ip Networks

Abstract

In this paper, an advanced distributed control scheme that connects the control networks to the IP networks, based on LonWorks technology, which is one of the control networks, are presented. The proposed approach is implemented by using a simple programmable basic Lon node (BLN) and a IBM PS/2 (PC) compatible computer as an Internet server. BLN is a developed electric board in this research and it physically contains a transceiver, Neuron chip and some memory devices. To perform various functions as an Internet server of PC, control software of Lon on internet system (LOIS) with C-language for GNUILINUX environment is also developed. Our approach makes system designers to easily implement their various specific applications, only with the download of a control program from serial port (RS-232) of PC.
