将每个场信号合理分配并连接到每个I/O点。只有确定设备的物理地址后，才

Distribute each field signal reasonably and connect it to each I/O point. Only after the physical address of the device is determined, can the program be written and the electrical connection diagram of the device can be drawn. Based on the consideration of the simplicity of finding the circuit and the regularity of the editing program, signals of the same type are generally allocated together. It should be noted that: some points are vacant, these are automatically generated in the software design, so the software design should be based on the actual situation. <br>Generally speaking, buttons, optical internal and external detection switches, limit switches, etc. in the control circuit are processed as the input signal of the programmable controller, and the AC contactor of the control motor is processed as the output object. The system needs one each for inside door, one outside door detection switch, one inside door detection switch, one door opener, one limit switch, one door opener manually, one door opener and one door close actuator, a total of 9 input points and 3 output points.

Allocate and connect each field signal reasonably to each I/O point. You can't write programs and map the electrical connections to your device until you have determined the physical address of your device. Based on the simpleness of finding lines and the regularity of editing programs, the same type of signals are generally assigned together. It should be noted that some points are vacant, these are automatically generated in the software design, so the software design should be based on the actual situation.<br>Generally speaking, the control circuit buttons, light internal and external detection switches, limit switches, etc. as a programmable controller input signal processing, control motor AC contactor as the output object to deal with. The system needs the door, door detection switch, door detection switch each one, open door, limit switch each one, manual door one, open door, close the door execution body each one, a total of 9 input points, 3 output points
