  CEA Irfu Saclay is involved as partner in the ESS accelerator construction
through different work-packages: controls for several RF test stands, for
cryomodule demonstrators, for the RFQ coupler test and for the conditioning
around 120 couplers and the tests of 8 cryomodules. Due to the high number of
components it is really crucial to automatize the conditioning. This paper
describes how the control of these test stands was done using the ESS EPICS
Environment and homemade EPICS modules. These custom modules were designed to
be as generic as possible for reuse in future similar platforms and
developments. They rely on the IOxOS FMC ADC3111 acquisition card, Beckhoff
EtherCAT modules and the MRF timing system.
