Sirius is a new 3 GeV synchrotron light source currently being designed at the Brazilian Synchrotron Light Laboratory (LNLS) in Campinas, Brazil. The Control System will be heavily distributed and digitally connected to all equipments in order to avoid analog signals cables. A three-layer control system is being planned. The equipment layer uses RS485 serial networks, running at 10Mbps, with a very light proprietary protocol, in order to achieve good performance. The middle layer, interconnecting these serial networks, is based on Single Board Computers, PCs and commercial switches. Operation layer will be composed of PC’s running Control System’s client programs. Special topology will be used for Fast Orbit Feedback with one 10Gbps switch between the beam position monitors electronics and a workstation for corrections calculation and orbit correctors. At the moment, EPICS is the best candidate to manage the Control System.
