How to self-study PLC

1, find a good book to read, recommended Liao Changchu's book, and Siemens Cui Jian's book, but the book do not die reading, involving the hardware part of the flip on the hardware part of the focus is the system structure, the relationship between hardware and software, the key to the software programming (that is to say, when I learned the s7 programming time have no information, which instruction to use to look at the online help)

2, there is a good material is the official training ppt out of the internet, very long and detailed, this can also turn over

3, software go to the next Siemens official training ppt out of the internet, it is very long and detailed. 2, there is a good material is the official training ppt of the Siemens company out on the Internet, very long and very detailed, this can also turn over

3, the software to go down a step7 professional version (with simulator plcsim), so that you can be programmed inside the computer and simulate the running test, familiar with the various types of basic commands

4, to give themselves some small topics, such as traffic lights, motor forward and reverse, robots, etc., more than a few ways to achieve

5, more on the industrial control forum to see the post

6, do not limit themselves to ladder programming, statement table and SCL are worth to learn

7, do not limit themselves to the PLC programming language, to learn a high-level language programming, such as VB, the experience of high-level language programming ideas, on the future of the PLC programming Great benefit (some people buried in a lifetime inside the PLC, vision can not see far after all, subject to step7 this platform is the openness of the strong you can not imagine)

Generally speaking, to do 2-3 years of engineering basically to achieve a more proficient degree (which almost everyone can reach), and then after the difference will be demonstrated (which is mainly the difference in knowledge of computers brought about by the difference, and often). Computer learning good people, plc programming level can reach a certain height), and then want to improve on their own enlightenment and opportunity (good project or encountered a high point)

I hope you can help.
