强大的功能，并且除了多种类型开关量及模拟量 I/O外，还有轴定位模块、Genius 通讯模块 等功能很强的特殊模块供选择。对于如 ACCU轧机控制这 类复杂的工业自动化应用场合而言，能提供更经济有效 的解决途径。本文以某公司已投入在线作业的ACCU 轧机 系统为例，描述了机组工艺流程、控制系统功能需求和 采用GE90-30PLC作为基本控制单元的整个控制系统设计 及实现。ACCU 轧机机组主要设备分布如图 1 所示。机组主要工艺 流程如下：穿孔后的毛管经星轮翻料机→月牙挡料钩→横 移链→对齐辊道→对齐辊道翻料钩→予穿台→芯棒插入→ 毛管步进梁→入口台限动小车启动→芯棒夹钳动作、芯棒 予旋转启动→斜送辊升起并旋转→限动小车前进到2.85 米 （可设定）限动位置→主
