This video series, although a few years old, is very good for covering the basics in a short, concise manner. However, the reason I was interested in it is for one particular feature it has that OpenPLC doesn’t - you can make your own basic HMI (human-machine interfaces) with it. Compared with OpenPLC, it is much more feature-rich (and more complex), able to interface with a large number of PLCs. However, as I was studying LL and ST, another piece of software kept being mentioned - CODESYS.Īccording to CODESYS, they are “the leading manufacturer-independent IEC 61131-3 automation software for engineering control systems”.
Until now I’ve used OpenPLC for all my PLC ( ladder logic) projects, as it’s very user-friendly and it makes using an Arduino as a PLC very simply.
