The main software used for Mitsubishi HMI is MELSOFT GT Works3, developed by Mitsubishi Electric. This software is designed specifically for creating and configuring screens for GOT series HMIs. Inside GT Works3, you’ll find GT Designer3, which is the tool used to design the HMI interface — including buttons, alarms, messages, and process visuals. It’s simple to use, supports drag-and-drop screen design, and allows simulation before downloading the program to the actual HMI device.
Along with GT Works3, Mitsubishi also provides GT SoftGOT, a PC-based runtime version of the GOT HMI. It lets you use your computer as a virtual HMI for testing or monitoring purposes. Together, GT Designer3, GT Works3, and GT SoftGOT form a complete package for design, simulation, and operation of Mitsubishi HMIs. Using this software ensures smooth communication between PLC and HMI, faster commissioning, and easier troubleshooting in industrial automation systems. In short, MELSOFT GT Works3 is the official and most reliable software for programming and operating Mitsubishi HMI.
