(一）分析被控对象并提出控制要求
&sp; &sp; 详细分析被控对象的工艺过程及工作特点，了解被控对象机、电、液之间的配合，提出被控
对象对PLC控制系统的控制要求，确定控制方案，拟定设计任务书。
&sp; &sp; （二）确定输入／输出设备
&sp; &sp; 根据系统的控制要求，确定系统所需的输入设备（如：按纽、位置开关、转换开关及各
种传感器等）和输出设备（如：接触器、电磁阀、信号指示灯及其它执行器等），从而确定与PLC
有关的输入/输出设备，以确定PLC的I/O点数。
&sp; &sp; （三）选择PLC
&sp; &sp; PLC选择包括对PLC的机型、容量、I/O模块、电源等的选择，详见本章第二节。
&sp; &sp; （四）分配I/O点并设计PLC外围硬件线路
&sp; &sp; 1.分配I/O画出PLC的I/O点与输入／输出设备的连接图或对应关系表，该部分也可在第２步中
进行。
&sp; &sp; 2.设计PLC外围硬件线路画出系统其它部分的电气线路图，包括主电路和未进入可编程控制器
的控制电路等。由PLC的I/O连接图和PLC外围电气线路图组成系统的电气原理图。到此为止系统的
硬件电气线路已经确定。
