Currently, in a scenario of Industry 4.0, the communication protocol is a key factor of success
for modern industry. Allits needs could be fulfilled by Ethernet based protocols. One of the …

Distributed architectures for industrial applications are a new opportunity to realize cost-
effective, flexible, scalable and reliable systems. Direct interfacing of sensors and actuators …

A trend, accompanying the change of automation systems and their architectures, is the
virtualization of software components. Virtualization strengthens platform-independent …

Ethernet technology is widely used in real-time industrial automation. Thanks to real-time
Ethernet (RTE) protocols, defined in IEC61784-2 standard, new top-performance automation …

In this paper, we are interested in the design of closed-loop control laws to satisfy a set of
temporal constraints in discrete event systems modeled by timed event graphs (TEGs). The …

This research deals with the temporal performance analysis of distributed networked
automation systems. It describes a new formal approach that estimates the maximum limit of …

In this paper, we present an analytic approach to evaluate the reactivity of client-server
networked automation systems (NASs). Both deterministic and probabilistic analyses are …

In this paper, an approach to evaluate time performances of networked control systems
(NCSs) is presented. Switched Ethernet with a client/server protocol is considered for …

This paper presents a novel two-step approach for modeling forward and backward network
delays in networked control systems (NCS). The first step is to build a colored Petri net …

In this paper, we address the problem of temporal performances evaluation of
producer/consumer networked control systems. The aim is to develop a formal method for …
