Engineering Software is Mitsubishi Electric's FA MELSOFT engineering-software umbrella — programming, HMI design, and motion tools for MELSEC, GOT, and motion controllers — not a single PLC CPU or hardware series. Confirm the package, version, and Thailand license form with TKK.

MELSOFT iQ Works

MELSOFT iQ Works Version 2 is the integrated suite option (site license SW2DND-IQWK-EC). MELSOFT Navigator provides system-level graphic configuration and system-wide project management. The suite package includes:

• MELSOFT Navigator — system management.
• MELSOFT GX Works3 and GX Works2 — PLC engineering.
• MELSOFT MT Works2 — motion-controller engineering.
• MELSOFT GT Works3 — HMI / GOT screen design.
• MELSOFT RT ToolBox3 mini — robot setup (simplified). Full RT ToolBox3 with simulation is a separate purchase.
• MELSOFT FR Configurator2 — inverter setup.
• MELSOFT CW Configurator — C Controller setting and monitoring.

Ask TKK which package fits your controllers, HMI, and motion layout.

GX Works3

MELSOFT GX Works3 is the primary PLC engineering environment for MELSEC MX, iQ-R, and iQ-F. Representative site license: SW1DND-GXW3-EC. The GX Works3 package also includes GX Works2 and PX Developer.

• Graphic-based system configuration and IEC 61131-3 languages (ladder, structured text, and related structured programming).
• Integrated Simple Motion / servo setup inside the GX Works3 project — distinct from dedicated motion-controller engineering in MT Works2.
• iQ-R Safety CPU: general and safety programs in the same GX Works3 project folder.

GT Works3

MELSOFT GT Works3 is the HMI / GOT screen design software. Representative site license: SW1DND-GTWK3-EC. Package contents for GOT families can change by release — confirm supported GOT models and included designers with TKK or Mitsubishi release notes.

MT Works2

MELSOFT MT Works2 is the motion-controller engineering software for dedicated motion CPUs (graphic programming and digital oscilloscope functions). Representative site license: SW1DND-MTW2-EC. Use MT Works2 for motion-controller projects; use GX Works3 when Simple Motion / servo setup is handled inside the PLC engineering environment.

GX Works2

MELSOFT GX Works2 remains available for installed-base continuity on older MELSEC platforms (for example Q, L, and FX3) and for continuity of existing project assets. It is bundled with the GX Works3 and iQ Works packages. It is not a peer on this page’s model line — current-platform designs should start from GX Works3.

Related MELSOFT tools for drives, servo setup, and C Controllers — FR Configurator2, MR Configurator2, and CW Configurator — are available as suite members or companion tools. Inquire with TKK for the right Thailand package; they are not billed as equal-weight sections on this umbrella page.
