摘要：This study researched from the introduction of PLC, combined with the characteristic of PLC, it discusses the design of full-automatic computer food controlling system based on PLC. Programmable Logic Controller (PLC) is automation equipment with microprocessor as the key and an electronic system working with figure in working environment. It can be easily interfaced and the programming language is easy to be accepted by engineering technicians. Graphic symbol and means of expression of ladder diagram language is rather close to circuit diagram of relay.
