Abstract. This paper presents the design and implementation of RT-EP (Real-Time Ethernet Protocol), which is a software-based token-passing Ethernet protocol for multipoint communications in real-time applications, that does not require any modification to existing Ethernet hardware. The protocol allows a fixed priority to be assigned to each message, and consequently well-known schedulability analysis techniques can be applied. A precise model of its timing behavior has been obtained. Furthermore, this protocol provides the ability of recovering from some fault conditions. It has been ported to an implementation of the Minimal Real-Time POSIX standard called MaRTE OS [10], and is being used to support real-time communications in an implementation of Ada’s Distributed Systems Annex (RT-GLADE). It has been successfully used to implement a distributed controlled for an industrial robot.

Abstract-In this paper, we propose a platform for the implementation of Distributed discrete event control systems. We propose an architecture for the Distributed implementation of Petri Nets (PN) in control applications. The architecture covers the local execution of PN and the communication amongst controllers. Both synchronous and asynchronous communication paradigm is supported. A framework of classes for supporting the real time communication and real time execution or remote calls has been developed. The Real Time Wireless Multi-hop Protocol has been adopted. With this protocol and the framework of classes developed, control deadlines of the system can be guaranteed. In order to solve access to common resources, a new class of communications places, the Auction Communication Places, is proposed. To support the real time and concurrent characteristics, we used the Java real-time specification. In order to implement PN, we have extended the concurrent coordinators technique, developed in previous works, to distributed systems introducing the distributed coordinators. To demonstrate the practical utility and feasibility of the architecture, we have applied it to the control of a flexible manufacturing cell. I.
