| Abstract: | In Order to enhance the stability and reliability of the control system, anti - interference capability must be improved in control system. An analysis is made on internal and external interference source of PLC system in the paper. Some concrete anti - interference measures are presented from the aspects of power supply, signal system, earthing system and so on.. For instance, 160tPLC control system of frame bending machine with manipulator controlled by programmable controller of Qingshan shipyard indicates that these measures are very useful for improving anti - interference capability and reliability of PLC control system. |
