MVME2604 712I/O 用于交换过程值的通信过程

PROFIBUS标准已有20多年的历史，是一种成熟的数字现场总线技术，用于许多工厂和过程自动化应用，以及食品、饮料和制药等混合行业。根据PROFIBUS和PROFINET国际(PI)协会，2015年销售了超过5000万台PROFIBUS设备，并且这个数字还在继续增长。让我们更深入地了解PROFIBUS，包括它是什么以及它是如何工作的。

PROFIBUS是过程现场总线的缩写，是自动化技术中领先的现场总线通信标准，支持使用单条总线电缆在网络内进行数字数据交换。目前，PROFIBUS有两种变体，最常用的是PROFIBUS DP(分散外设),用于通过集中控制器操作传感器和执行器。

PROFIBUS通常使用EIA-485传输技术作为其物理层。EIA-485基于带有一对阻抗为150欧姆的双绞线的屏蔽铜电缆，支持多达126个站连接到一个PROFIBUS DP网络，支持线性总线拓扑。现场总线数据链路(FDL)协议定义了PROFIBUS数据链路层。通过令牌传递，FDL定义了网络访问，并区分了主站和从站。它还控制单个主机的时隙。

PROFIBUS DP设备类型有哪些？

根据PROFIBUS DP，有三种设备类型:

1. PROFIBUS DP主站等级1。该类控制用于交换过程值的通信过程，在配置的时隙期间，各个从设备使用定义的循环命令。设备包括控制器和个人电脑。
2. PROFIBUS DP主站等级2。该类通过使用非循环服务访问现场总线，实现智能现场设备的配置和参数化。设备包括工程和操作面板。
3. PROFIBUS DP从站。这些外围设备读取输入信息并将输出信息发送到外围设备。器件最多可以处理246字节的输入数据和244字节的输出数据。
