Distributed automation is unthinkable without adequate communication. This fact was discovered quite early, and from the first ideas of computer integrated manufacturing onwards, the need for networks in automation has been addressed. This chapter reviews the history of fieldbus systems and the problems of standardization and sheds light on the complex variety of existing approaches. Furthermore, it will discuss the recent adoption of Internet technologies and Ethernet as automation network and the ongoing work to overcome its real-time limitations. Finally, we address evolution prospects and current research issues ranging from the apparent security problem and synchronization mechanisms in distributed systems to entirely new approaches like bionics-inspired concepts.
