The control system of the RIKEN RI-Beam Factory (RIBF) is based on the Experimental Physics and Industrial Control System (EPICS). To control magnet power supplies of cyclotrons and their beam transport lines, we are using VME and CAMAC as I/O Controllers (IOCs) depending on a kind of their interface boards. To control beam-diagnostic equipment and vacuum systems, small single-board computers mounted with Linux are used as IOCs. Other devices of cyclotrons like RF are controlled by PCs, which are independent systems from EPICS. These details will be reported. Furthermore, we will report about the RIBF beam interlock system using Melsec PLCs. We started beam commissioning of RIBF in July 2006 and succeeded in extracting uranium beam from the Superconducting Ring Cyclotron (SRC), which is the last of the multi-stage accelerators of the RIBF, on March 23, 2007.
