  RIKEN Radioactive Isotope Beam Factory (RIBF) is a cyclotron-based heavy-ion accelerator facility for producing unstable nuclei and studying their properties. Many components of the RIBF accelerator complex are controlled by using the Experimental Physics and Industrial Control System (EPICS). We will here present the overview of the EPICS-based RIBF control system and its latest update work in progress. We are developing a new beam interlock system from scratch for applying to some of the small experimental facility in the RIBF accelerator complex. The new beam interlock system is based on a programmable logic controller (PLC) as well as the existing beam interlock system of RIBF (BIS), however, we newly employ a Linux-based PLC-CPU on which EPICS programs can be executed in addition to a sequencer in order to speed up the system. After optimize the performance of the system while continuing operation, we plan to expand the new system as a successor to the BIS that has been working more than 10 years since the start of its operation.
