The S-DALINAC (Superconducting Darmstadt Linear Accelerator) is an electron accelerator for energies from 3 MeV up to 130 MeV. It supplies beams of either spin-polarized or unpolarized electrons for experiments in the field of nuclear structure physics and related areas of fundamental research. The migration of the Accelerator Control System to an EPICS-based system started three years ago and has essentially been done in parallel to regular operation. While it has not been finished yet it already pervades all the different aspects of the control system. The hardware is interfaced by EPICS Input/Output Controllers. User interfaces are designed with Control System Studio (CSS) and BOY (Best Operator Interface Yet). Latest activities are aimed at the completion of the migration of the beamline devices to EPICS. Furthermore, higher-level aspects can now be approached more intensely. This includes the introduction of efficient alarm-handling capabilities as well as making use of interconnections between formerly separated parts of the system. This contribution will outline the architecture of the S-DALINAC's Accelerator Control System and report about latest achievements in detail.
