However, although it has the reliability which like on states high, antijamming ability stronger, but works as production environment is too bad, electromagnetic interference specially intense, or installs uses is improper, possibly creates the program error or the operation mistake, thus produces inputs by mistake and causes outputs by mistake, this will be able to create the equipment out of control and the disoperation, thus will not be able to guarantee PLC the normal operation, will have to enhance the PLC control system reliability, on the one hand will request PLC to produce the factory to enhance the equipment the antijamming ability; on the other hand, in the request design, the installment and the use maintenance cause highly takes, coordinates to be able in every way to consummate solves the problem, effectively strengthens the system the resistance to interference.

然而，尽管有如上所述的可靠性较高，抗干扰能力较强，但当生产环境过于恶劣，电磁干扰特别强烈，或安装使用不当，就可能造成程序错误或运算错误，从而产生误输入并引起误输出，这将会造成设备的失控和误动作，从而不能保证PLC的正常运行，要提高PLC控制系统可靠性，一方面要求PLC生产厂家提高设备的抗干扰能力；另一方面，要求设计、安装和使用维护中引起高度重视，多方配合才能完善解决问题，有效地增强系统的抗干扰性能。
