主流现场总线简介
下面就几种主流的现场总线做一简单介绍。
1 基金会现场总线（Foundation Fieldbus 简称 FF）
这是以美国Fisher-Rousemount公司为首的联合了横河、ABB、西门子、英维斯等80家公司制定的ISP协议和以Honeywell公司为首的联合欧洲等地150余家公司制定的WorldFIP协议于1994年9月合并的。该总线在过程自动化领域得到了广泛的应用，具有良好的发展前景。

基金会现场总线采用化组织ISO的开放化系统互联OSI的简化模型（1，2，7层），即物理层、数据链路层、应用层，另外增加了用户层。FF分低速H1和高速H2两种通信速率，前者传输速率为31.25Kbit/秒，通信距离可达1900m，可支持总线供电和本质安全防爆环境。后者传输速率为1Mbit/秒和2.5Mbit/秒，通信距离为750m和500m，支持双绞线、光缆和无线发射，协议符号IEC1158-2标准。FF的物理媒介的传输信号采用曼切斯特编码。
2 CAN（Controller Area Network 控制器局域网）
最早由德国BOSCH公司推出，它广泛用于离散控制领域，其总线规范已被ISO组织制定为，得到了Intel、Motorola、NEC等公司的支持。CAN协议分为二层：物理层和数据链路层。CAN的信号传输采用短帧结构，传输时间短，具有自动关闭功能，具有较强的抗干扰能力。CAN支持多主工作方式，并采用了非破坏性总线仲裁技术，通过设置优先级来避免冲突，通讯距离最远可达10KM/5Kbps/s，通讯速率最高可达40M /1Mbp/s，网络节点数实际可达110个。目前已有多家公司开发了符合CAN协议的通信芯片。
3 Lonworks
它由美国Echelon公司推出，并由Motorola、Toshiba公司共同倡导。它采用ISO/OSI模型的全部７层通讯协议，采用面向对象的设计方法，通过网络变量把网络通信设计简化为参数设置。支持双绞线、同轴电缆、光缆和红外线等多种通信介质，通讯速率从300bit/s至1.5M/s不等，直接通信距离可达2700m（78Kbit/s），被誉为通用控制网络。Lonworks技术采用的LonTalk协议被封装到Neuron（神经元）的芯片中，并得以实现。采用Lonworks技术和神经元芯片的产品，被广泛应用在楼宇自动化、家庭自动化、保安系统、办公设备、交通运输、工业过程控制等行业。
