PLC is a device specially developed for industrial automatic control. Usually, PLC uses “natural language” programming oriented to control process and problems. The products of different manufacturers use different programming languages, such as ladder diagram, statement table, control system flow chart, etc. In order to enhance the various operation functions of PLC, some PLCs are also equipped with BASIC language, and are exploring the use of other high-level languages for programming.

The PLC products produced by FANUC, Lishi, Mitsubishi and Fuji in Japan all adopt ladder diagram programming. When a programmer is used to input a program to the PLC, the general simple programmer uses the code table for input, and the large programmer can also use the ladder diagram for direct input. In many PLC products, due to different manufacturers, the representation method of the instruction system and the mnemonic in the statement table are also different, but the principle is completely the same. In this book, we take FANUC-PMC-L as an example to introduce the PLC instructions applicable to the control of CNC machine tools. In FANUC series PLC, the specifications and models are different, but the number of functional instructions is different. For example, there are 23 FANUC-BESK PLC-B functional instructions developed jointly by Beijing Machine Tool Research Institute and FANUC Company. In addition, the instruction system is completely the same.
