过程自动化级由 ALPHA 小型机和工业计算机组成，完成对生产工艺过程的跟踪和控制，它们也通过基于光缆的以太网与PLC 和HMI进行通讯；生产线上的各类检测仪表（测厚、测宽、测力及测温等）则分别通过直接I/O 或通讯的方式与PLC完成信号传递。另外，还根据各厂的实际情况为轧线供辅系统（液压站、稀油润滑站、高压水除鳞泵站等）配置了若干台由中、小型PLC 控制器构成的控制系统，并且这些 PLC 可以通过现场总线（PROFIBUS-DP、GENIUS 等）与轧线 PLC、HMI进行通讯。系列 90-30 PLC 成本低，性能高，能方便地取代从简便的继电器到复杂的中型自动化应用系统场合。它的 CPU具有强大的功能，如内置 PID调节，结构化编程，中断控制，间接寻址及各种功能模块，能完成复杂的操作。另外系列90-30 有功能很强的特殊模块可供选择，如高速计数模块，
