7、合理地配置可编程序控制器系统的冗余
可编程序控制系统可能做出多种方式的冗余，处理器的双机热备、冷备冗余是常见的方式。另外，双系统冗余，即处理器和全部的输入、输出、组网通信完全冗余，其价格和实用性虽然在许多工程项目中难以被人接受，但在有毒、有害的化工生产环境这种冗余很有必要。在设计系统中，要使配置冗余方式较为经济而又实用，力求使故障缩小在本设备身上。不要因某一设备发生故障，引起工艺流程中相关设备运行或状态受到冲击。
以上阐述的几个方面，是在可编程序控制系统总体方案设计时，要格外重视的问题，只有在设计系统时，考虑周到，系统投入运行之后，设计人员才能少些遗憾。
1．输入程序
2．检查电气线路
3．模拟调试
模拟调试可以采用系统提供的模拟台调试，也可以在关闭系统强电的条件下模拟调试，例如关闭主轴强电空开，那么调试中即使PLC动作有误，由于主轴电动机不会实际运转，所以也不会引起事故。
