To boost up the intensity of the uranium beam accelerated in the RIKEN RI Beam Factory (RIBF), a new 28GHz superconducting ECR ion source was constructed in 2008. The standalone commissioning of the ion source has started in early 2009. In order to control the ion source as a part of the RIBF accelerator complex, we introduced F3RP61-2L as IOCs and integrated them into the existing EPICS-based RIBF control system. F3RP61-2L is a new CPU module running Linux, which functions with the I/O modules of FA-M3 PLC on the PLC-bus. We have confirmed stable operation of EPICS on F3RP61-2L and found that the new IOC makes our control system simpler and easier to maintain. We will report the details of the control system of the new ion source and its integration into the whole RIBF control system.
