Controls Software Documentation

This page exists to collect links to documentation about the instrument control system EPICS, its modules and related libraries (synApps, areaDetector), as used at the Advanced Photon Source.

Documentation referenced should be appropriate for beamline scientists, as opposed to only EPICS developers. New deployments should prefer EPICSv7, the latest release series.

See also the extensive resources from past EPICS Collaboration meetings.
