Creating and experimenting with a relay PLC using openplc and raspberry pi

If you have a Raspberry Pi 4, you can teach remotely, and you can also use VNC to control the screen from a remote location, in case you want to conduct the experiment in another room on the same LAN. VNC (Virtual Network Computing) is the ability to call up the screen of another computer to your own computer and control it from your own computer. This is different from a VPN (Virtual Private Network). By using OpenPLC for this, learning sequence control can be done without a PC. Let's learn the basics of controlling sequences with Raspberry Pi 4+OpenPLC.
