A new type of Input / Output Controller (IOC) has been developed based on F3RP61, a CPU module of FA-M3 Programmable Logic Controller (PLC). Since the CPU module runs Linux, it takes no special effort to run EPICS IOC core program on the CPU module. With the aid of wide variety of I/O modules of FA-M3 PLC, the F3RP61based IOC has various applications in accelerator controls, such as magnet power supply control, stepping motor control, data acquisition from beam monitors, monitoring interlock status and so forth. The adoption of the new IOC makes the architecture of accelerator control systems simpler by unifying the two layers of front-end computers, i.e., the IOC layer and the PLC layer, into one layer. We found that the simplification of the control system architecture helps us to reduce the time and cost for the development and maintenance of application software.
