Plc mainly refers to the programmable logic controller of the digital operation operating electronic system, which is used to control the mechanical production process. So how can I learn the plc major?
To learn PLC, you must first choose the PLC of that manufacturer. The integration of Japanese PLC internal software is simple. The early OMRON, Mitsubishi applications are more, now because of the trade and international cooperation relationship Siemens clc, Rockwell's more, (although learning a brand is profound, others will soon get started, but People's energy is limited. We must use our limited energy in one of the most widely used, potential, and development directions. However, we know everything about PLCs, including imported and domestic ones. Corresponding understanding, for each PLC's characteristics, advantages and disadvantages, these have a better understanding, then will be a rare talent in the market.)
PLC is not a single programming technique, it is a system professional course. PLC can be broadly considered to be a highly reliable PC with a back embedded operating system. First of all, it is necessary to deepen the PLC programming language ladder diagram and statement list language. At this level you can only read the programmed program and design some engineering needs. In this industry, it is also necessary to apply VB and VC++ to realize serial communication and distributed control system. Knowledge of the database is also needed in some large programs.
PLC is a discipline that focuses on the application direction. So you have to practice a little more. Don't look down on small projects where you can sum up the logical thinking of the design process. Continuous improvement in the summary. For example, every time you go to the field to debug, you can call the program on the spot to view it. From the above, the structure of the program is different from other programs, so the progress is faster.
