Petri nets, as a graphical and mathematical tool, provide a uniform environment for
modelling, formal analysis, and design of discrete event systems. The main objective of this …

Field-level networks have been one of the keys to modern automation systems. Be it in
factory, process, or building automation, networks allow for horizontal and vertical …

The recent performance improvements of wireless communication systems are making
possible the use of such networks for industrial applications, which typically impose severe …

The aim of this paper is to discuss the problems relating to communication in distributed
process control, highlighting the limits of traditional centralized communication systems …

The IEC 61158 is on the way to become an international fieldbus standard after a long
period of contrasts and misunderstandings. The final standard document results from the …

The delays associated with the use of Profibus process automation (PA) networks within
control loops are investigated in this paper. A SMAR IF303 device, a SMAR FI303 device, a …

The delays associated with the use of foundation fieldbus (FF) H1 networks within control
loops are investigated in this paper. A Smar IF302 device, a Smar FI302 device, a DeltaV …

The paper deals with the problem of scheduling the transmission of periodic processes in a
distributed FieldBus system, defining the conditions guaranteeing correct transmission. The …

This paper presents the use of Hopfield-type neural networks for process scheduling in the
area of factory automation, where bus-based communication systems, called FieldBuses …

This paper describes the pilot implementation of a local area network by using a hybrid
medium access control (MAC) layer protocol, called group implicit token-carrier sense …
