How to learn *PLC technology systematically?
Thread Content
Are there any good books or courses?
1. There are many types of PLCs, and it’s not necessary to learn them all*. The ones that are most commonly used in China include Siemens, Omron, Rockwell, and so on. You only need to learn one type; once you master it, it will be much easier to learn other PLCs. You should first learn the PLC type that you use in your work, otherwise the learning process might take longer. 2. Each manufacturer has its own Chinese-language website, where you can register to download learning materials. 3. You can download PLC video tutorials from Southeast University online, or download Siemens’ training e-materials from Siemens’ website. 4. Recommended book: Electrical and PLC Control.
It’s best to start with hardware, as that will be faster. There are too many PLC brands these days; let’s learn just one at a time. I suggest you check out some relevant websites. It is recommended to buy a book titled \"Electrical Control and PLC Application Technology\". The first half of this book covers the electrical components commonly used in control cabinets as well as basic circuits, while the second half deals with the applications of PLCs.
There are many brands of PLCs, and each brand uses a different programming language. Even when ladder diagrams are used, the algorithms remain the same, but the ways in which they are expressed vary. There is a book on the forum, I think it’s titled \"Understanding Siemens S7‑200 PLCs from the Basics to Practical Examples\", covering everything from the most fundamental concepts to various case studies. The better approach is to program the PLC according to its actual application.
The major PLC brand manufacturers or distributors hold lectures and seminars from time to time; attending such events can be beneficial. It would be even better if your employer allows you to go to companies like Siemens, AB, and others that produce PLCs to attend their paid courses
First, one needs to understand the working principle of PLCs. Then, learn one specific brand, such as Siemens; take a PLC project that has already been developed by someone else, and study it while reading relevant materials.
It’s best to work on a small project with an expert yourself; it’s easy to learn this way
