Evaluation of Response Time in Ethernet-based Automation Systems

This paper presents a method to assess response time of automation system architectures including industrial switched Ethernet networks using client/server protocols. The method relies upon modeling the behavior of the components of these architectures in the form of hierarchical timed colored Petri nets and upon simulation of these models. A case study exemplifies the method and shows how it can facilitate design of automation systems including this kind of industrial Ethernet networks.
