A control system designed for today's large experimental physics projects is likely to be in operation for decades. Over the lifetime of a facility, computer hardware technologies will change, custom electronics designs will face obsolescence, and software and computing technologies will evolve. The control system must be designed to work from the onset of operations, while also adapting to changes in technology, requirements and science priorities. Using the ongoing upgrade of the Spallation Neutron Source beam line controls and data acquisition systems as a case study, this paper will offer lessons learned for future control system designs.

  EPICS version 4 is a set of software modules that add to the base of the EPICS toolkit for advanced control systems. Version 4 adds the possibility of process variable values of structured data, an introspection interface for dynamic typing plus some standard types, high-performance streaming, and a new front-end processing database for managing complex data I/O. A synchronous RPC-style facility has also been added so that the EPICS environment supports service-oriented architecture. We introduce EPICS and the new features of version 4. Then we describe selected deployments, particularly for high-throughput experiment data transport, experiment data management, beam dynamics and infrastructure data.
