ntrol system using single chip microputer as the control core. The programmable controller is integrated puter technology, automatic control technology and munication technology and developed a new type of industrial control devices, it has high reliability, easy programming, easy maintenance and other advantages, has been in the field of industrial control has been widely used. Because the vending machines as social plete retail and integrated services of independent facility, its structure must be reliable, stable and high efficiency. But PLC also has its own characteristics, PLC in the identified tasks, in special procedures to bee a special machine, which uses circular scanning mode, system of job management and execution of the application program is pleted by cyclic scanning.Keyword: Vending machine programmable logic controller PLC關鍵詞之間加分號目 錄1. 引言 2 2 自動售貨機的基本功能描述 2 自動售貨機的控制工藝分析 32.
