    Abstract
  • The fundamental and means of realization of fault diagnosis was introduced, which can be applied in the dynamic system controlled by PLC controller. In order to improve the reliability of the control system, one method that is realized by programming the ladder diagram to make use of the output module to shield the exception points was presented, which can realize fault detection and tolerance control function in the running process of the dynamic control system and can be even enable the system to run with fault. The applied instance illustrated that the method is very feasible in avoiding or reducing the fault effect on system.
