| Abstract: | Several methods of program design of fault detection for PLC control system were presented based on different fault of control system, including the self detection of fault signals generating firstly, the judgement of logic of state and the detection of time limit. The methods of display of fault signals were given as well. These methods are useful for raising the reliability and safety of PLC systems. |
