摘　　要：研究了NetLinx协议的构架,提出了一种适用于ControlLogix控制器的远程操作系统。该系统通过虚拟专用网技术,建立起客户端与现场设备的远程连接;通过RADIUS进行用户认证、账号管理、服务器运行状态查询等管理工作;通过上位机组态软件,实行对设备的组态操作。客户端还允许对控制器进行调试,上载或下载程序,通过实时视频观察现场设备的运行状态。该系统运行稳定,实时性好,可操作性强,作为网络化系统控制实验室的实施方案投入使用。The remote control system was designed for the ControlLogix based on the NetLinx architecture. This system built the communication between the client and instructions in the lab by VPN. RADIUS would afford user authentication, account management and server monitoring. The clients operated the instruments of the lab by configuration software and also upload or download the programs of the ControlLogix. The status of instrument could be observed through real time stream video provided by the server. The experiment shows that the system runs stably, real-time responses fast and used friendly and this remote control system has been applied as the network control laboratory project.
