The instrument control software framework "IROHA2" is used for the neutron and muon experiments at J-PARC MLF. IROHA2 consists of four core software components: i) The device control server controls and monitors devices, ii) the instrument management server authenticates users, manages measurements and configures device combinations, iii) the sequence management server builds and controls automatic measurements, iv) the integrate control server has centralized control over the device monitoring and measurement. Since IROHA2 is equipped with a web user interface, the control system can be accessed remotely using a web browser. MLF's sample environment team developed several device modules of the device control server in order to be able to use the sample environment equipment for automatic measurements. For example, the modules currently used in the experiments are those for He and He cryostats, superconducting magnets, niobium furnaces, and so on. In this presentation, we will introduce the features of IROHA2 and the functions of the device modules for the sample environment equipment.
