目前部分厂家已推出了符合或接近iec61131-3标准的编程软件，但是仍然有相当多的plc产品的编程语言与iec6113l-3有较大的差异。尽管如此，各种plc产品在软件上还是比较接近的，学好了一种plc的编程语言，再学别的plc就比较容易了。
程序：plc指令的有序集合，plc运行它，可进行相应的工作，当然，这里的程序是指plc的用户程序。用户程序一般由用户设计，plc的厂家或代销商不提供。用语句表达的程序不大直观，可读性差，特别是较复杂的程序，更难读，所以多数程序用梯形图表达。
第二部分是自诊断处理。plc每扫描一次，执行—次自诊断检查，确定plc自身的动作是否正常。如cpu、电池电压、程序存储器、i／o和通讯等是否异常或出错，如检查出异常时，cpu面板上的led及异常继电器会接通，在特殊寄存器中会存入出错代码。当出现致命错误时，cpu被强制为stop方式，所有的扫描便停止。
一个企业，应尽量做到plc的机型统一。主要考虑到以下三方面问题：
2）软件模拟法是在plc中另外编写一套模拟程序，模拟提供现场信号，其简单易行，但时效性不易保证。模拟调试过程中，可采用分段调试的方法。，并利用编程器的监控功能。
指令表编程语言是与汇编语言类似的一种助记符编程语言，和汇编语言一样由操作码和操作数组成。在无计算机的情况下，适合采用plc手持编程器对用户程序进行编制。同时，指令表编程语言与梯形图编程语言图一一对应，在plc编程软件下可以相互转换。图3就是与图2plc梯形图对应的指令表
