可编程控制器的应用设计[***讲]——可编程控制系统设计的七个步骤
　　设计一个PLC控制系统需要以下七个步骤：
　　?1.?系统设计与设备选型
　　?a.?分析你所控制的设备或系统。PLC最主要的目的是控制外部系统。这个系统可能是单个机器，机群或一个生产过程。
　　?b.?判断一下你所要控制的设备或系统的输入输出点数是否符合可编程控制器的点数要求。（选型要求）
　　?c.?判断一下你所要控制的设备或系统的复杂程度，分析内存容量是否够。
　　?2.?I/O赋值（分配输入输出）
　　?a.?将你所要控制的设备或系统的输入信号进行赋值，与PLC的输入编号相对应。（列表）
　　?b.?将你所要控制的设备或系统的输出信号进行赋值，与PLC的输出编号相对应。（列表）
