5 PLC的网络及发展趋势

　　 一个或若干PLC与PC机联出系统，PC机起到原编程器及人机界面操作站的作用，这20世纪90年代的新潮流，这样为系统集成带来了商机，同时编程软件和人机界面软件(监控软件或称组态软件)及软件接口(或称驱动软件)也得到了发展。

　　 近年来，PLC厂家在原来CPU模板上提供物理层RS232/422/485接口的基础，逐渐增加了各种通讯接口，而且提供完整的通讯网络。由于近来数据通讯技术发展很快，用户对开放性要求很强烈，现场总线技术及以太网技术也同步发展，所以PLC构成的PCS系统比DCS的开放性所处的现状稍好一些。目前罗克韦尔AB公司已形成了多层结构体系，即Ether Net、Control Net、Device Net及Asi等现场总线(原DH+网也可兼容)。西门子公司在Profibus-DP通讯网络及Profibus-FMS网络以外，提出了S7 Routing网络，即Profibus-DP和Industrial Enternet两层结构。网络还在发展，我国应已积极的姿态投入其中。
