It's a bit difficult to start learning DCS, which requires a certain theoretical basis. You need to know the principle of automatic control, the knowledge of digital and analog electricity, a little programming language (now the configuration of DCS is much simpler, most of them are in the form of functional blocks, and VB is used when writing scripts), the knowledge of communication networks, and the basic knowledge of computers (system installation, hardware configuration, etc.). ). You don't need a lot of field instrument knowledge, but you can understand DCS system faster if you know it.

After a little foundation, I will find a mature DCS system to learn. There are systems of Zhejiang University Kong Zhong, Beijing Hollysys and Shanghai Xinhua (acquired by GE) in China. There are Honeywell's PKS 300, Yokogawa's CS3000, Emerson's Delta V Siemens' PCS 7 and ABB's industrial Foxboro's I/A system abroad. There is no need to learn from others. Find one. It's not that hard. Learned one, other systems are similar, the essence is similar, very easy to use.
