2.PLC的软件设计
挂面在刚刚生产出来时，并非像我们平时见到的那样短小，而是长度约1.3米的长长的一串，因此为了适合人们的食用以及方便运输，需要将其切割为长度适当的若干段。
PLC以可靠性高、抗干扰能力强而著称，但现代工业对可靠性要求越来越高，用户仍然希望下一代PLC的故障检测与处理能力将会更强。据统计，在PLC控制系统的故障中，CPU和I/O仅占20%，而输入输出设备、线路故障占80%。前者可通过PLC软件本身的软硬件实现检测、处理，而故障须加强研制、发展用于检测外部故障的专用智能模块，进一步提高系统的可靠性。
(1)提供**的编程特性，易于组态便于安装。
4)输入继电器的状态地取决于对应的外部输入电路的通断状态，因此在梯形图中不能出现输入继电器的线圈
3)梯形图中各编程元件的常开触点和常闭触点均可以无限多次地使用。
