HASP/ACLD, ACSSs one of the famous simulation programs that had developed in Japan. Despite the sophisticated algorithm and its high accuracy, this program has not use to the public because of the problem in its usability. To make it use as a commissioning tool, we have developed interface software, which run on Windows operating system and help data input/output by GUI and other extended functions. This paper also shows an application example to commissioning with new software.
