10.2.- 控制器与工业通讯

随着大型工业厂房控制的发展,出现了一种新型的系统,在这种系统中,控制不再由单一的设备来实现:分布式控制系统或DCS。在这些系统中,待自动化的过程被划分为简单的控制回路,由工业控制器和/或可编程逻辑控制器(PLC)进行本地调节,并由中央监督控制和数据采集系统(SCADA)进行监督。这种分散式的结构使得不同设备之间必须建立一个操作层次(CIM模型或金字塔),并建立一个允许信息流动的通信网络。

在CIM自动化模型中,上层与监督和生产计划有关,下层用于过程控制。在下层中是现场设备(传感器和执行器)和相关的局部控制器。这些级别的工业通信采用现场总线的方式,用多点数字网络取代传统4-20mA电流回路的点对点连接。这些通信由各种协议和标准管理,包括HART、现场总线基金会、Profibus、Modbus、Profinet、以太网和AS-i。

工业通信的最新发展包括无线系统和协议、增加的远程功能和操作、嵌入式网络服务器和通过人机界面设备的移动控制。
