Profibus DP cable specification Our Profibus DP cables represent the optimised performance version of the more generic profibus cable range. These cables are specifically designed to deliver time-critical communication between process automation systems and distributed peripherals. They are widely used in fa...
每个PROFIBUS-DP系统可包括以下三种不同类型设备:① 一级DP主站(DPM1):一级DP主站是中央控制器,它在预定的周期内与分散的站(如DP从站)交换信息。典型的DPM1如PLC或PC。②二级DP主站(DPM2):二级DP主站是编程器.组态设备或操作面板,在DP系统组态操作时使用,完成系统操作和监视目的。③ DP从站:DP从站是进行输...

1 PROFIBUS 概述PROFIBUS网络通讯的本质是RS485串口通讯,按照不同的行业应用,主要有三种通讯行规: DP(Decentralized Pe 3、ripherals),FMS(Field Message Specification)和PA(Process Automation)行规。其中DP通讯的方式在OSI参考模型中主要使用第1、2、7层,因此PROFIBUS DP网络的通讯 速度较快,且报文简单(表1)。第...
PROFIBUS由3个兼容部分组成,即PROFIBUS-DP(Decentralized Periphery,分布I/O系统)、PROFIBUS-PA(Process Automation,现场总线信息规范)和PROFIBUS-FMS(Fieldbus Message Specification,过程自动化)。 PROFIBUS-DP是一种高速、低成本通信,专门用于设备级控制系统与分散式I/O的通信。使用PROFIBUS-DP可取代24V DC或4~20mA信号...
网络拓扑是线性总线,两端带终端器或不带终端器,包括短截线(drop cable)和分支(树) 介质、距离、站点数取决于信号特性,如对屏蔽双绞线,≤1∙2公里(不带中继器),32个站点。 数据传输速率取决于网络拓扑和总线长度,从9.6 kbit/s到1.5 Mbits/s不等。 后备介质(冗余)是可选的。 在传输时,使用半双工,异步,滑...
