Design and development of programmable controller based on Embedded Technology

With the development of social productivity, people's requirements for industrial automation continue to improve, the proportion of industrial automation equipment in the production process is growing. At present, PLC controller has been widely used in various fields and industries. Usually, the core of a complete embedded system is embedded processor and embedded operating system. Embedded processor belongs to chip industry, and the related industry chain has been very mature. Embedded processors can be subdivided into design, wafer manufacturing, packaging and testing. In this paper, a low-cost PLC controller design scheme is proposed. From the aspects of hardware circuit construction, product reliability design and software design, Bing explains in detail the PLC controller hardware and software design and specific implementation.
