ACCU 轧机控制系统设计基于这样的思想：满足工艺设备 要求，确保自动化水平，优化系统结构，增强运行的稳定 性。本系统采用美国GE公司的系列90-30 PLC作基本控制单元，完成整个轧机在线设备的自动控制功能。系列90-30 PLC具有系统易扩展、配置灵活、交互式编程、界面友好、易于操作、系统功能强、具有 I / O 点监测报警、易于查找等特点，是完成现代工业自动控制的一种较理想设备。控制系统由两台PLC组成，实现对 ACCU轧机在线7个分区的控制，两台PLC通Genius通讯模块进行相互的控制数据交换。所有调速装置作为PROFIBUS-DP从站，连入DP现场总线网络。通过两个PLC中CPU单元（CPU364）的以太网接口连接到HUB或以太网交换机，进而与上位机PC连接。系统配置如
