Electrical and Mechanical Interface Characteristics and Line Control Protocol Using Communication Control Characters for Serial Data Link Between a Direct Numerical Control System and Numerical Control Equipment Employing Asynchronous Full Duplex Transmission (Stabilized: May 2016)
直接数控系统和采用异步全双工传输的数控设备之间串行数据链路的电气和机械接口特性以及使用通信控制字符的线路控制协议(稳定:2016年5月)
The increasing use of computers and related equipment in Direct Numericai Control (DNCI) Systems for storage and distribution of machine programs to numerically controlled machines and for communication between various components of DNC systems has demonstrated the need for a standard data communication link between the DNC and the numerical control unit. As a result, the EIA Committee IE-31 which is made up of representatives of numerical control system builders, machine builders and users has prepared this standard for use by people specifying, building and using DNC systems.
