摘要
基于EPA通信规范与EPA协议一致性测试规范,研究了对EPA网络进行确定性调度测试的方法,阐述了EPA网络确定性调度测试的实现技术。实践证明,开发的EPA协议确定性调度测试系统,可读取/修改目标设备的组态信息,可还原EPA网络上的报文传输情况,并能对EPA网络进行确定性调度测试。
This paper is based on standard of EPA communication protocol and EPA protocol conformance test, method of EPA network deterministic scheduler test has been studied,and the realization technology of EPA network deterministic scheduler test has expounded. It is proved that this scheduler test software is able to read/write configuration information of target device,reinstate the network packet transmission,and test the deterministic scheduler of EPA network.
