充分发挥PLC的功能，最大限度地满足被控对象的控制要求，是设计PLC控制系统的首要前提，这也是设计中最重要的一条原则。这就要求设计人员在设计前就要深入现场进行调查研究，收集控制现场的资料，收集相关先进的国内、国外资料。同时要注意和现场的工程管理人员、工程技术人员、现场操作人员紧密配合，拟定控制方案，共同解决设计中的重点问题和疑难问题。
还有更进一步冗余的，采用三取一的设计，CPU、I/O模块、电源模块都冗余或其中的部分冗余。三套同时工作，最终输出取决于三者中的多数决定的结果。这可使系统出故障的机率几乎为零，做到万无一失。当然，这样的系统成本是很高的，只用于特别重要的场合，如铁路车站的道叉控制系统。
