Nakatani, Takeshi ; Inamura, Yasuhiro  ; Moriyama, Kentaro*

The instrument control software framework "IROHA2" have been introduced and used in several neutron instruments at MLF, J-PARC. IROHA2 consists of several severs, which are the device control, the instrument management, the sequence management and the integrate control. Users cooperate to use these servers to carry out their experiments with a web browser. By the development since last year, new features are implemented to IROHA2 as follows: (1) Real-time data processing interface on the device control server with a distributed messaging middleware, (2) Flexible web user interfaces for automatic measurements on the sequence management server, (3) Remote experimental status monitoring system on the integrate control server, which is access controlled by the MLF integrate authorization system. We will report the implementation status and future plans of IROHA2.
