The working sequence of colored lights is as follows: 1. LD 1 Lights turn off after 5 seconds. 2. Next, the LD2 colored lamp lights up for 3 seconds, and then flashes three times (every cycle is 1 second and then goes out). Enter the recycling and repeat the process of (1)~(2) continuously. Analyze the meaning of the question, the program is coming to an end.

-Siemens PLC 200 has some special relays SM as shown in the figure, which can simplify our programming through reasonable use. Today, we will introduce the ingenious usage of SM 1.0, and use SM 1.0 to realize the circular control of colored lights with the shift command. Example: Use a switch to control eight lights, which will be introduced later.

-17 PLC control of lantern circular lighting Chapter 1 Introduction and characteristics of PLC1.1History and development of PLC The first PLC recognized in the world was developed by Digital Equipment Company (DEC) of the United States in 1.969. What is microcosmic appeared in the early 1970s.

—— The selected editable pptPage.docin The editable pptPage selected by the kitten lights up in turn. After it is completely lit, the flashing 1 goes out in reverse order, and the time interval is still that the lamp is lit, and the cycle begins. Fig. 8- 1 A neon sign on a billboard.

—— Practice 7 PLC control of lantern circular lighting 1. Training purpose (1) To master the basic operation of FXGP programming software; (2) Master the basic methods and skills of programming; (3) Familiar with the external wiring of PLC. Second, training equipment (l will be introduced later.

-There are four colored lights (L 1~L4), which are lit in turn, and each light is only lit for 3S. Programming ladder diagram program with Mitsubishi PLC! Interpretation of I/O address assignment program When the start button x000 is pressed, the coil of M 1 is energized, the normally open contact of M 1 is closed and self-locked, and the coil of M0 is energized, which will be introduced later.

-Step 1: Start the program and send the initial value to the bit combination elements of Y0~Y 12. K 1 stands for Y0. A light lights up at 1 (ON), which can be changed as needed to start the cycle. Step 2, stop the program, reset the cycle and reset the interval Y0~Y 1.
