A few years into development of the new control system for FAIR (Facility for Antiproton and Ion Research), a first version of the new settings management system is available. As a basis, the CERN LSA framework (LHC Software Architecture) is being used and enhanced in collaboration between GSI and CERN. New aspects, like flexible cycle lengths, have already been introduced while concepts for other requirements, like parallel beam operation at FAIR, are being developed. At SIS18, LSA settings management is currently being utilized for testing new machine models and operation modes relevant for FAIR. Based upon experience with SIS18, a generic model for ring accelerators has been created that will be used throughout the new facility. It will also be deployed for commissioning and operation of CRYRING by the end of 2014. During development, new challenges came up. To ease collaboration, the LSA code base has been split into common and institute specific modules. An equivalent solution for the database level is still to be found. Besides technical issues, a data-driven system like LSA requires high-quality data. To ensure this, organizational processes need to be put in place at GSI.

The FAIR facility makes use of the General Machine Timing (GMT) system and the Bunch phase Timing System (BuTiS) to realize the synchronization of two machines. In order to realize the bunch to bucket transfer, firstly, the source machine slightly detunes its RF frequency at its RF flattop. Secondly, the source and target machines exchange packets over the timing network shortly before the transfer and make use of the RF frequency-beat method to realize the synchronization between both machines with accuracy better than 1o. The data of the packet includes RF frequency, timestamp of the zero-crossing point of the RF signal, harmonic number and bunch/bucket position. Finally, both machines have all information of each other and can calculate the coarse window and create announce signals for triggering kickers.
