一、LON技术简介 1993年,美国Echelon公司发表了一项称为LON-WORKS的新的现场总线技术,它提供了一个开放性很强的、无专利权的低层通信网络——局部操作网络(LOCAL OPERATING NETWORK),简称LON。 1.现场总线技术 LON这种全分布式智能通信网络实际上是一种工控网,因此,在介绍LON技术之前,先介绍一下现场总线技术。现场总线是用于现场仪表与控制室之间的一 I. INTRODUCTION OF LON TECHNOLOGY In 1993, Echelon Company of the United States published a new fieldbus technology called LON-WORKS, which provides a low-level and open communication network with no patent rights - local operation network LOCAL OPERATING NETWORK), referred to as LON. 1. Fieldbus technology LON This fully distributed intelligent communication network is actually an industrial network, therefore, before introducing LON technology, first introduce the field bus technology. Fieldbus is used between field instrumentation and control room
