  Diamond Light Source is actively investigating the use of EtherCAT-based Remote I/O modules for the next phase of photon beamline construction. Ethernet-based I/O in general is attractive, because of reduced equipment footprint, flexible configuration and reduced cabling. EtherCAT offers, in addition, the possibility of using inexpensive Ethernet hardware, off-the-shelf components with a throughput comparable to current VME based solutions. This paper presents the work to integrate EtherCAT-based I/O to the EPICS control system, listing platform decisions, requirement considerations and software design, and discussing the use of real-time pre-emptive Linux extensions to support high-rate devices that require deterministic sampling.
