摘　　要：针对一个实际的工厂自动化PROFINET IO实时网络进行测试研究。由于该网络应用了PROFINET IO实时等级1和2级(非同步)的设备,包含较多分布式IO、执行器和传感器,而且拓扑结构复杂(包含星形和环形),非一般实验室设备能仿真,所以选定该网络进行测试具有实际参考意义。测试的实时参数可以用来改进仿真模型,并验证真实生产条件下的紧急情况。The paper presents a case study regarding a real PROFINET IO network for factory automation. The aim of the study is the evaluation of the time related parameter of a real network. A large factory automation plant has been chosen as testbed since PROFINET IO RT Class 1 and 2 （unsynchronized） are mainly used in those applications. The analyzed network has a high number of distributed IO, actuators and sensors; its topology is complex （star and ring）; and it is fully operative （in-production）. The considered implementation stresses the PROFINET IO communication as no laboratory setup can do, giving meaningful information about real operative conditions on short-term. The results of this case study can be used both to improve imulation models of devices and to verify critical situations in real plants.
