这两个例子说明：同样的若干条梯形图，其排列次序不同，执行的结果也不同。另外，也可以看到：采用扫描用户程序的运行结果与继电器控制装置的硬逻辑并行运行的结果有所区别。当然，如果扫描周期所占用的时间对整个运行来说可以忽略，那么二者之间就没有什么区别了。
编程器用作用户程序的编制、编辑、调试和监视，还可以通过其键盘去调用和显示plc的一些内部状态和系统参数。它经过接口与cpu联系，完成人机对话。
20世纪80年代初，小型plc在价格上还高于小系统用的继电器控制装置。随着微电子技术的发展，新型器件大幅度的提高功能和降低价格，使plc结构更为紧凑，功能不断增加，将原来大、中型plc才有的功能移植到小型plc上，如模拟量处理、数据通讯和复杂的功能指令等，但价格不断下降，真正成为继电器控制系统的替代产品。
保证plc控制系统能够长期安全、可靠、稳定运行，是设计控制系统的重要原则。这就要求设计者在系统设计、元器件选择、软件编程上要全面考虑，以确保控制系统安全可靠。例如：应该保证plc程序不仅在正常条件下运行，而且在非正常情况下（如突然掉电再上电、按钮按错等），也能正常工作。
plcopen运动标准的第四部分，包含运动控制功能块，将plc、机器人和运动控制集成到一种易于理解的、并在很多厂商比较常见的语言中。一般情况下，这些转变功能块由供应商提供，所以对大多数生产制造商而言，如果运动控制器不支持，则不能添加此功能。该标准支持scara和delta，但除此之外，任何编程人员都可以编写自己的运动转换功能。
通过修改与调试后的程序称为用户执行程序，由于不需要再作修改与调试，所以用户执行程序就被固化到eprom内长期使用。
2)手动复位型热继电器，其常闭触点可以在plc的输出电路中与控制电机的交流接触器的线圈串联。
