1、一个系统中使用的成熟技术至少应占到75%以上
“成熟技术”一是经过一定的生产实践考验的可编程控制器产品或类似设计，或者确定能在未来的生产实践中，经得起考验；二是设计工作人员对于需要使用的技术要有经验或有掌握它的能力。设计与配置一个可编程序控制系统选用的技术与设计方案切实可行。因为一个生产过程控制系统，一旦做出来，要长久使用下去，难以找到机会反复修改。设计的硬件系统和编程软件，其中某些缺欠，可能一直隐藏在已完成的系统中。若遇到发生破坏作用的条件，后果难以预料。
2、系统的硬件结构和网络要简明而清晰
硬件结构不要追求繁琐，网络组态不要追求交叉因素太多，要力求使用可编程序控制器自身配置的组网能力。在组成I/O机箱配套的模板时，建议型号简单，力求一致，模板密度不宜过大。使用的结线点不宜过多，从目前机箱的制造和配线工艺来看，输入与输出配线密度不能太高。
