SuperKEKB is the upgrade of the KEKB asymmetric energy e⁺e⁻ collider, for the B-factory experiment in Japan, designed to achieve a 40-times higher luminosity than the world record by KEKB. The KEKB control system was based on EPICS at the equipment layer and scripting languages at the operation layer. The SuperKEKB control system continues to employ those features, while we implement additional technologies for the successful operation at such a high luminosity. In the accelerator control network system, we introduce 10GbE for the wider bandwidth data transfer, and redundant configurations for reliability. The network security is also enhanced. For the SuperKEKB construction, the wireless network is installed into the beamline tunnel. In the timing system, the new configuration for positron beams is required. We have developed the faster response beam abort system, interface modules to control thousands magnet power supplies, and the monitoring system for the final focusing superconducting magnets to assure stable operations. We introduce the EPICS embedded PLC, where EPICS runs on a CPU module. The design and status of the SuperKEKB accelerator control system will be presented.

There were more than 2500 magnet power supplies for KEKB storage rings and injection beam transport lines. For the remote control of such a large number of power supplies, we have developed the Power Supply Interface Controller Module (PSICM), which is plugged into each power supply. It has a microprocessor, ARCNET interface, trigger signal input interface, and parallel interface to the power supply. The PSICM is not only an interface card but also controls synchronous operation of the multiple power supplies with an arbitrary tracking curve. For SuperKEKB, the upgrade of KEKB, most of the existing power supplies continues while handreds of new power suplies are also installed. Although the PSICMs have worked without serious problem for 12 years, it seems too hard to keep maintenance for the next decade because of the discontinued parts. Thus we have developed the upgraded version of the PSICM. The new PSICM has the fully backward compatible interface to the power supply. The enhanced features are high speed ARCNET communication and redundant trigger signals. The design and the status of the upgraded PSICM are presented.
