The Swiss Light Source is a high brightness synchrotron light source at the Paul Scherrer Institute in Switzerland. It consists of a 100 MeV electron Linac, a booster synchrotron, a 2.4 GeV storage ring, and experimental beam lines. The machine and beamline control system consist of 150 VME crates running Epics on Motorola power PC processors. The network is based on switched 100mbit/sec and Gigabit Ethernet technology. Consoles and servers are PCs running Linux. To achieve high availability of the control system, emphasis has been put on software engineering and the use of a relational database for all system configuration. Most hardware channels are directly connected to VME input/output cards rather than using a field-bus, and this has resulted in higher performance, better reliability, and reduced costs. Any of the 100,000 data channels can be archived at high speed, and the resulting data accessed through the Web. The VME input/output cards can be 'hot-swapped' in case of failure, and have circular buffers for post-mortem analysis in case of beam loss. Having all machine parameters available through the control system in a consistent and easy to use manner has contributed to the fast and successful commissioning of the machine.
