The SACLA linac will be used as the injector of the SPring-8 storage ring. The MADOCA control framework was created 20 years ago and has contributed to the stable operation of both SPring-8 and SACLA. However, we must integrate separated control systems of two machines for the upgrade. In addition, some new ICT standard protocols designed recently have the potential to simplify the implementation of the framework. With these background, we have developed a new messaging system MS-MQTT and a new DAQ system MDAQ, based on the concepts of simple, easy management and unified operation covering SPring-8 and SACLA. For the equipment control hardware, we have adopted the modern architecture of MTCA.4 and Ether-CAT. We are developing a universal driver for MTCA.4 modules. A pilot application of the new control system including the new hardware was performed at the RF test stand. The result of high power RF operation showed that the high stability required for the RF amplitude and phase in the cavity was achieved using the new system. We confirmed that the new framework can control SPring-8-II.

The SACLA generate brilliant coherent X-ray beams with wavelength of below 0.1nm and the SPring-8 provides brilliant X-ray to large number of experimental users. On the SPring-8 upgrade project we have a plan to use the linac of SACLA for a fullenergy injector of the storage ring. For this purpose, two accelerators should be controlled seamlessly and the SACLA has to provide low emittance electron beam to generate X-ray laser and injector for the SPring-8 simultaneously. We start the design of control system to meet these requirements. We redesign all of a control framework such as Database, Messaging System and Equipment Control include with NoSQL database, MQTT and EtherCAT. In this paper, we report the design of control system for SACLA/SPring-8 together with status of the SPring-8 upgrade project.
