The Spiral2 project is aiming to provide high intensity rare ion beams for nuclear physics experiments. It is based first on a primary beam driver accelerator consisting of a RFQ followed by a superconducting L. I.N. A.C., then a rare ion production process delivers the beam either to a low energy experimental area or to the existing Ganil facility. The EPICS software has been chosen as the basic framework to improve efficient collaboration between several research laboratories (CEA-IRFU, CNRS-IPHC, GANIL) which are designing the accelerator control system. The whole facility will integrate more than 600 power supplies used for the magnetic and high voltage equipment control of the accelerator. It has been decided to interface these power supplies through the MODBUS/TCP protocol, using Ethernet as a field bus. This paper introduces the EPICS software archetype set up to assess the practicability of such a solution and presents a first implantation for prototyping.
