A neutron scattering experiment in MLF of J-PARC is done while changing measurement conditions. Variations of measurement conditions can be automatically done by the control software of the experimental instrument in MLF. In 2013, we have upgraded our standard control software framework of the instruments. The new framework, named "IROHA2" is more user-friend, available, flexible and scalable than the original IROHA. Last year, we have developed the sequence management server based on IROHA2 for an automatic measurement. The sequence management server has the functions which are not only sequential control but also feedback control with exchanging the parameters between control commands. The sequence management server has the web user interfaces as well as other software components of IROHA2. The interface is to edit the sequence of the automatic measurement, to run control the sequence and to monitor the sequence graphically. We will report the sequence management server of IROHA2.
