plc的程序一定要正确，并要经过实际工作验证，证明其能够正确工作。这是对plc程序的zui根本的要求，若这一点做不到，其它的再好也没有用。

要使程序正确，一定要准确的使用指令，正确的使用内部器件。准确的使用指令与准确理解指令相，为此对指令含义和使用条件一定要弄清楚。必要时，可编些小程序对一些不清楚的指令作些测试。

同一指令，由于plc的出厂批次不同或是plc的系列型号的不同，一些指令细节有可能不一样，应仔细查阅编程手册。

内部器件正确使用也是重要的。如有的plc有掉电保护，有的plc没有。一定要做到该掉电保护的一定要用掉电保护的器件，反之则不能用。

总之，要准确的使用指令，正确使用内部器件，使所编的程序能正确要作，这是对plc程序zui根本的要求。

2、可靠性

程序不仅要正确，还要可靠。可靠反映着plc程序的稳定性，这也是对plc程序的基本要求。

有的plc程序，在正常的工作条件下或合法操作时能正确工作，而出现非正常工作条件（如临时停电，又很快再通电）或进行非法操作（如一些按钮不按顺序按，或同时按若干按钮）后，程序就不能正常工作了。这种程序，就不大可靠，或说不稳定，就是不好的程序。

好的plc程序对非正常工作条件出现，能予以识别，并能使其与正常条件衔接，可使程序适应于多种情况。好的plc程序对非法操作能予以拒绝，且不留下“痕迹”。只接受合法操作。

联锁是拒绝非法操作常用的手段，继电电路常用这个方法，plc也可继承这个方法。
