The Control System will be distributed and digitally connected to all equipment in order to avoid analog signal cables. A three-layer control system will be used. The equipment layer uses RS485 serial networks, running at 10Mbps, with a light proprietary protocol, over a proprietary hardware, in order to achieve good performance. The middle layer, interconnecting these serial networks, is based on Beaglebone Black single board computer and commercial switches. Operation layer will be composed of PC's running EPICS client programs. Special topology will be used for Orbit Feedback with a dedicated commercial 10Gbps switch. The lower layers software implementation may use either (a) distributed EPICS conventional servers, the traditional approach, or (b) centralized EPICS server, using data servers and light proprietary protocol over Ethernet. Both cases use the same hardware and can run concurrently, sharing the control network. Measured performance with these two approaches will be presented.
