3.4 Single chip microcomputer , PLC programmable design and control virtual simulation software:
This software is developed based on Unity3D, with built-in experimental steps, experimental instructions, circuit diagrams, component lists, connection lines, power on, circuit diagrams, scene reset, return and other buttons. After the connection and code are correct, the 3D machine model can be operated through the start/stop, forward motion, and reverse motion buttons . When the line is connected, the 3D machine model can be enlarged/reduced and translated.
1. Relay control: Read the experimental instructions and enter the experiment. By reading the circuit diagram, select relays, thermal relays, switches and other components in the component list and drag and drop them into the electrical cabinet. The limiter is placed on the 3D machine model. You can choose to cover the lid. Some component names can be renamed. Then click the connection line button to connect the terminals to the terminals. After the machine circuit is successfully connected, choose to turn on the power and operate. If the component or line connection is wrong, an error box will pop up, and the scene can be reset at any time.
2. PLC control: The experiment is the same as relay control, with the addition of PLC control function. After the connection is completed, press the PLC coding button to enter the program writing interface, and write two programs, forward and reverse. There are 12 ladder diagram symbols in total. After writing, select Submit to verify the program. After successful verification, turn on the power to operate. Error boxes will pop up for components, line connections, and code errors, and the scene can be reset at any time.
3. MCU control: The experiment is the same as relay control, with the addition of MCU control function. After the connection is completed, press the C coding button to enter the programming interface, enter the correct C language code, and submit for successful verification. Turn on the power to operate. Error boxes will pop up for components, line connections, and code errors, and the scene can be reset at any time.
