ndustrial control process flow diagram of the bus involved in the process, light equipment, boards, carefully drawing then make the control system more clear image and vivid. Advanced and convenient touchscreen input technology are the second highlights in the it apply a convenient input to the third highlights is that Light equipment offline detection. So We use from time to time ask, from the node offline detection. In short, in this design, the master node to multiple remote setup and monitoring functions of light equipment from the node offline detection, run munication indicator, updated in real time slave node With independent settings, control the function of the lamp device of the node from the node. The overall system is reliable, normal munication, the munication congestion, crashes and so on. And develop system software and hardware with a certain significance of application to achieve effective control of the lighting equipment.
