 1 GFK-1291A1章简介1-13 Profibus Profibus是一种串行现场总线，用于内部控制和I/O信息。Profibus由几个独立的协议组成，其中常见的是Profibus FMS和Profibus DP。Profibus FMS用于控制器之间的通信，其中通信服务比系统反应时间更重要。Profibus DP用于I/O级的高速数据传输，包括传感器和致动器。GE Fanuc现场控制Profibus BIU支持Profibus DP协议。Profibus为主设备和从设备提供服务。主设备能够控制总线。当它有权访问总线时，主机可以在没有远程请求的情况下传输消息。从设备是简单的外围设备，如传感器、致动器、变送器或模块化I/O单元，如GE Fanuc现场控制Profibus BIU。从属设备没有总线访问权限，它们只能确认接收到的消息，或者在主设备的请求下向该主设备发送消息。Profibus的协议架构基于开放系统互连（OSI）参考模型，符合国际标准ISO 7498。总线规范网络拓扑线性总线，两端终止。存根是可能的。中屏蔽双绞线电缆。根据环境的不同，可以省略屏蔽。车站数量每段32个车站1 GFK-1291A Chapter 1 Introduction 1-13 Profibus Profibus is a serial fieldbus that is used for both inter-control and I/O information. Profibus consists of several separate protocols, the most common of which are Profibus-FMS and Profibus-DP. Profibus-FMS is used for communication between controllers, where communications services are more important than system reaction time. Profibus-DP is used for high-speed data transfer at the I/O level, including sensors and actuators. The GE Fanuc Field Control Profibus BIU supports Profibus-DP protocol. Profibus serves both master and slave devices.
Master devices are able to control the bus. When it has the right to access the bus, a master may transfer messages without remote request.
Slave devices are simple peripheral devices such as sensors, actuators, transmitters, or a modular I/O unit such as the GE Fanuc Field Control Profibus BIU. Slaves have no bus access rights—they may only acknowledge received messages, or at the request of a master, transmit messages to that master. The protocol architecture of Profibus is based on the Open Systems Interconnection (OSI) reference model in accordance with the international standard ISO 7498. Bus Specifications Network Topology Linear bus, terminated at both ends. Stubs are possible. Medium Shielded twisted pair cable. Shielding may be omitted, depending on the environment. Number of Stations 32 stations in every segment
