MTCA workshop for accelerator and physics in Japan 2021 was held from October 26-28 2021 in a virtual format. The goal of this workshop is to boost the application of MTCA in Japan by exchanging the information and experiences. The first day was dedicated for the tutorial session in Japanese and the other two days consisted of oral presentations. The workshop was very successful with more than 120 registered participants. The summary and outlook are presented.

The number of the MTCA systems in Japan Proton Accelerator Research Complex (J-PARC) is steadily increasing. The LLRF control system of the main ring (MR) was fully replaced with the new system based on MTCA.4. The R&D of the LLRF systems for the UHF and L-band parts of the future muon linac has been started. The systems employ the COTS RFSoC AMCs, contrary to the other applications in J-PARC that employ custom AMCs. The status and future plan of the MTCA application in J-PARC are presented.

Japan Atomic Energy Agency is developing control and data acquisition systems for poloidai polarimeter, edge Thomson scattering system, divertor impurity monitor, IR thermography and micro fission chamber in ITER project. We developed supervisory control system, which coordinates internal devices such as detectors and laser system following discharge sequence, leading other domestic agencies. Supervisory system configures measurement parameters and performs consistency check between the parameters. We also developed sequence control function to coordinate control programs for measurement and auxiliary devices complying to ITER standards and guidelines. A flowchart conversion tool was developed. The conversion tool reduced troubles in the program codes. It also makes changes of control logic flexible. We also developed prototype data acquisition system communicating with a central control simulator. The prototype demonstrates that our system design was valid.
