摘　　要：介绍了具有DeviceNet现场总线通信接口的电动执行器的开发过程。保留了原有电动执行器现场控制功能,增加了DeviceNet远程控制和故障信号的采集。给出了软硬件实现方案和程序流程图,并详细讨论了DeviceNet对象模型的建立和在Keil C中对象化的实现方法。该电动执行器支持组态软件的接入并实现与其他DeviceNet现场总线产品的互连、互操作。In this paper,the development process of an electric actuator with DeviceNet fieldbus communica-tion interface is introduced. The formal functions of the electric actuator are reserved,and the DeviceNet remote control and error signals feedback are added. The hardware solutions and the software flowchart are given,and the emphasis is placed on the DeviceNet object modeling and the implement method in Keil C. The electric actuator can get access to DeviceNet network through configuration software to communic...
