摘　　要：随着可编程控制器应用范围加大,其需要支持的总线类型也不断增多,亟需一种通用的、可扩展的总线开发设计方法,以提升总线开发集成效率。采用层次化信息描述文件对总线和模块进行建模,组态软件以树形结构展现总线树,支持配置EtherCAT、Modbus、IEC61850和LocalBus等各种工业总线。采用组件库方式实现总线的功能,控制器运行时软件支持多种类型的总线库加载运行,支持总线配置内容在线增量更新。基于提出的通用建模配置和运行管理方法,新增一种数据总线时,控制器和组态软件都无需做适配修改,提升了系统的适配能力和可靠性。With the expansion of the application range of programmable controller,it needs to support more and more bus types,so a general and extensible bus development design method is urgently needed to improve the efficiency of bus development configuration.In this paper,the hierarchical information description file is used to model the bus and module,and the configuration software displays the bus tree in a tree structure,supporting the configuration of EtherCAT,Modbus,IEC61850 and LocalBus and other industrial buses.Component library is used to realize the bus function.The controller runtime software supports multiple types of bus library loading and running,and supports online incremental update of bus configuration content.Based on the general modeling configuration and operation management method proposed in this paper,when a new data bus is added,the controller and configuration software do not need to make adaptation modifications,which improves the adaptation ability and reliability of the system.
