由以上结构图可以看出，此系统分为两个网络层，从控 制器到远程 I/O采集器采用 GENIUS 现场总线，从控制 器到人机界面采用标准的工业以太网，这样的结构不仅 有利于第三发方设备的加入，同时采用标准的工业以太 网，有利于企业过程控制自动化、办公自动化以及企业 ERP的无缝衔接。在此系统中烧结 PAC 和配料 PAC 各自配置一个独立的 GENIUS总线控制器（IC697BEM731）用于管理各自独立的 GENIUS 现场总线。同时从整个控制工艺来说，配料系统 和烧结系统之间的设备存在互相关联，所以必然的存在数 据交换，但是由于现场环境的限制，无法通过以太网来连 接他们，所以我们通过光纤来连接两个PAC。
