The accelerator control architecture in KEK evolved in several steps. Several control systems employed a combination of several fieldbuses. In order to consolidate the efforts on the development and maintenance, some of the fieldbuses were gradually removed and many controllers were directly attached to IP networks.

At the same time, the EPICS control software framework was employed, and eventually many controllers evolved to embed EPICS IOC software, the same as on other EPICS control components.

Common pieces of IOC software communicated with others using a common protocol called channel access (CA), which realized a unified application development environment from top to bottom. We call this embedded EPICS framework CA everywhere, and it enabled both rapid development and smooth maintenance.

Developed controllers include:
