In the past 10 years, with the continuous reduction of the price of PLC controller and the continuous expansion of user demand, more and more small and medium-sized equipment began to use PLC controller for control, and the application of PLC controller in China grew rapidly. With the rapid development of the economy and the continuous improvement of the basic automation level, PLC controllers will still maintain a high growth momentum in China in the future.
For systems with the same I/O points, the cost of using PLC controller is lower than that of using DCS (about 40% can be saved). PLC has no special operation station, its software and hardware are universal, and its maintenance cost is far lower than DCS. The PLC controller can receive thousands of I/O points (up to 8000 I/Os). If the control object is mainly equipment interlocking and the circuit is less, PLC is more suitable. Because PLC uses general monitoring software, it is easier to design enterprise management information system.

1. Main board, also known as main board, system board, logic board, main board, backplane, etc. It is the center or main circuit board of a complex electronic system such as an electronic computer.
2. Computer chassis motherboard is also called motherboard, system board or motherboard; It is divided into commercial motherboard and industrial motherboard. It is installed in the chassis and is one of the most basic and important components of the microcomputer. The main board is generally a rectangular circuit board, on which the main circuit system of the computer is installed, generally including BIOS chip, I/O control chip, keyboard and panel control switch interface, indicator connector, expansion slot, DC power connector of the main board and card, etc.
