The trend in the design of complex instruments is toward distributed control systems implemented with networks of embedded devices. Historically these embedded networks have been implemented using field busses such as CAN, LonWorks, or ProfiNet but the ubiquitous nature and low cost of Ethernet has made it the trend in embedded network applications. Ethernet, however, largely depends on DHCP and DNS servers or static IP addressing scheme to enable communication between devices on the network. This paper presents a service-oriented architecture for self-configuring Ethernet-based distributed control systems that is able to adapt to changes in network topology without manual intervention.
