三菱电机EZMontion-NC E60/E68 系列数控系统（CNC）DDB 接口说明书（中文）阐述了在运行由用户PLC 的梯形图语言进行编程时，通过CNC 实现数据输入输出的DDB（Direct Data Bus）功能加以说明。对通过PLC 使用DDB 功能，读/写NC 的各种信息的方法加以记述。三菱电机EZMontion-NC E60系列数控系统（CNC）PLC联机操作手册（中文）是为用户在控制设备上进行PLC程序开发而编制的。在控制设备上执行PLC操作称为联机操作。联机操作的包含以下主要功能：
(1) 创建新的梯形图文件
(2) 编辑现有的梯形图(例如读写插入和删除)
(3) 梯形图回路监控
system fully embodies the Industrial” (Industrial Information) system pioneered and led by ABB in technology.
information technology) new trends.
The system is divided into two levels: operation management level and process control level. At the operation management level, not only the traditional control system monitoring operation function is realized

can. The process control stage realizes various loop adjustments including complex control (various PID, ratio, Simith, etc.) and high-speed logic control.
Control, sequence control and batch intermittent control functions.
The internal communication of the process control station (between the controller and various intelligent devices such as I/0 or field instruments) adopts the international standard field controller.
Wire. The field controller supports various field buses such as Profibus. Profibus is the most widely used open field bus in the world.
Line international standard, divided into FMS, DP and PA three levels, DP communication rate can be as high as 12Mb. The CAN (DIN/IS011898 standard) bus
The biggest feature is its super sturdiness and data security. The system of course also supports Modbus. The communication with the intelligent field instrument is through
IART protocol or field bus (31. 25Kb ProfibusPA and FF bus).
The system communication between the operation management level and the process control level is realized by Di giNetS network (Industrial Ethernet/IEEE802.3 standard),
Users can choose the communication transmission medium (ordinary cable or optical fiber) and network topology according to the actual situation of the application.
The popular PC and MS_ Windows 2000 have been widely used in various fields all over the world, becoming the de facto standard computer platform.
tower. The operating station 0S, the engineering station ES and the data gateway GS of the Industrial” system use this platform to ensure the system’s
Versatility, openness and ease of use, and bring great convenience to future technical upgrades and maintenance.
