1、所编的程序要符合所使用的PLC的有关的规定

主要是对指令要准确地理解,正确地使用。各种PLC指令多有类似之处,但还有些差异。对于有PLC使用经验的人,当选用另一种不太熟悉的型号进行编程设计时,一定要对新型号PLC的指令重新理解一遍,否则容易出错。

2、要使所编的程序尽可能简洁

简短的程序可以节省内存,简化调试,而且还可节省执行指令的时间,提高对输入的响应速度。要使所编的程序简短,就要注意编程方法,用好指令,用巧指令,还要能优化结构。要实现某种功能,一般而言,在达到的目的相同时,用功能强的指令比用功能单一的指令,程序步数可能会少些。

3、要使所编的程序尽可能清晰

这样既便于程序的调试、修改或补充,也便于别人了解和读懂程序。要想使程序清晰,就要注意程序的层次,讲究模块化、标准化。特别是在编制复杂的程序时,更要注意程序的层次,可积累自己的与吸收别人的经验,整理出一些标准的具有典型功能的程序,并尽可能使程序单元化,像计算机中的常用的一些子程序一样,移来移去都能用,这样,设计起来简单,别人也易了解。
