The DeviceNet has being widely used in the field of automation on the world for its outstanding advantages. With the development of DeviceNet devices increasing,the conformance of DeviceNet devices attracts more and more attention. Based on the analysis of the DeviceNet protocol and the related conformance test specifications, the test items are analyzed, and the hardware and software structures are designed and a time model is build. The testing solutions are given in the examples of the testing of identity object, DeviceNet object and response time.%DeviceNet现场总线以其独有的优势在自动化领域得到了广泛应用,随着设备厂商对DeviceNet设备的开发日益增多,DeviceNet设备的一致性测试愈发受到重视.根据DeviceNet协议与相关规范,分析了DeviceNet从站设备的软件一致性测试项目,设计了测试系统的硬件与软件结构,构建了测试系统的时间模型,并以标识对象、DeviceNet对象和响应时间的测试为例,给出了具体测试方法.
