Note that the PLC output module here should use transistor or thyristor output units, rather than relay output units. Because the relay output unit is a contact switch with slow response and low speed, it is not suitable for high-frequency on/off, It is also not suitable for dynamic data display [1]. Therefore, OMRON CJ1W-OD261 (64 points) is used in Figure 1 The transistor serves as the output unit, and its IO address allocation on this PLC rack is 6.00-9.15. Here, channel 0006 is used as the internal data display channel. 6.00-6.03 are the data input terminals A, B, C, and D of CD4511, where A is the lowest bit and D is the highest bit, which are high level locked data. The four digit data terminals are controlled by PLC's 6.04-6.07, and the four digital tubes occupy a total of 8 output points. 2.2 Generation of gating signals: Due to the fact that all four digital tubes are controlled by one I/O port, at each moment, the four LED lights will display the same characters.

To display different characters for each, it is necessary to use scanning to turn on each LED, that is, only one character is displayed at each moment. Display the corresponding character for each time division. According to the visual characteristics of the human eye, when the signal frequency of the LED is greater than 50Hz, the human eye cannot feel its changes. Therefore, the interval between each display should not exceed 20ms, which means that all LEDs should be lit up in time within 20ms. The more LEDs there are, the shorter the time division will be, and the brightness will be insufficient; If the lighting time is increased, it will also cause a decrease in scanning frequency, which can cause flickering sensation and easily cause eye strain. Therefore, dynamic scanning is often used
