The public beamlines in MLF, J-PARC carry out many kinds of measurements and produce huge experimental data by users. It is important to be user-friendly and automated control software for efficient measurements. We have developed the MLF standard instrument control software framework "IROHA2". IROHA2 consists of the device control server to control and monitor each device, the instrument management server to authenticate a user, manage a measurement and configure an instrument setup, the sequence management server to do an automatic measurement and the integrate control server to unify instrument control and monitoring. Because each software component of IROHA2 has a web interface, we are able to use its all functions under multi-platform environment via a web browser. IROHA2 is also connected to and cooperated with several other systems which are the experimental status system, the MLF integrated authentication system and the MLF business database.
