PLC are classified in various ways.

According to their structural forms, they can be divided into integral PLC, modular PLC and stacked PLCs. The CPU, I/O interface, memory, power supply, etc. of the integrated PLC are all fixedly installed on one or several printed circuit boards to form a unified whole; while the modular PLC is a combination of these parts in the form of modules according to certain rules. Become. Stacked PLC combines the characteristics of integral and modular.

According to the control scale, PLC can be divided into microcomputer, minicomputer, medium-sized computer, mainframe computer and supercomputer. The number of I/O points of microcomputers is less than 64 points and the memory capacity is small; while the number of I/O points and memory capacity of mainframes and supercomputers are larger, and they are suitable for large and complex control systems.

For laser cutting machines, if a large amount of cutting work is required and the cutting process is relatively fixed, you can choose to use PLC as the main station controller of the cutting machine. For example, GCANPLC is a combined PLC that can expand the IO interface according to actual needs, up to 512 channels of IO expansion, and is very suitable for laser cutting machine control systems that require a high degree of customization and scalability.

In addition, the control methods of laser cutting machines also include CNC control, manual control and automatic control. CNC control is one of the most important control methods, which controls the operation of the cutting machine through preset programs. Manual control is controlled through manual methods such as joysticks and buttons, and is mainly used for debugging or operations under special circumstances. Automatic control is based on real-time collection of data such as digital signals and sensors. Controlling the equipment through programs can greatly improve processing efficiency and accuracy.

When choosing a PLC, you also need to consider its stability, reliability, ease of maintenance and other factors to ensure that the laser cutting machine can operate stably and efficiently. At the same time, depending on factors such as the type, thickness, and processing requirements of the cutting material, it may be necessary to choose different focus control methods, such as cutting focus on the workpiece surface, cutting focus on the workpiece, or cutting focus inside the workpiece, etc.
