摘要
论述了一种基于Lonworks网络技术的电动通风/排烟窗智能控制系统。该系统采用WAGO 750现场总线控制器,底层采用三菱FX系列PLC构成网络智能控制节点。控制节点(区域)采用起止式异步通讯协议和地址映射通讯方式与上层总线控制器进行通讯,较好地解决了PLC与WAGO 750双向通讯问题。
This paper studies a intelligent control system for electric ventilating / smoke exhaust window based on Lonworks network technology. This kind of system adopts WAGO 750 field bus controllers. And the bottom layer utilizes FX series PLC from Mitsubishi to build intelligent control network nodes. The control nodes (areas) utilize start- stop type asynchronous communication protocol and address mapping to communicate with the upper bus controllers, which can solve the two-way communication between PLC and WAGO 750.
