A new 28 GHz electron resonance ion source has been installed upstream of them. Its control system will be consisted of Yokogawa FA-M3 series which is a porgrammble logic controller (PLC) with EPICS because of many achievements in case of RIBF control system. On the other hand, in the previous system with PLCs there was a disadvantage of low reliability for communications between PLC stations. Additionally, some devices (eg, oven, mivoc etc.) are changed for the generation of various kind of ions each times, therefore higher expandability is required. In the new system, we have designed the control system by utilizing star topology fieldbus for communications between the PLC stations to establish safety and expandability. In this conference, we report on the details of the system.
