: Mitsubishi Electric Americas maintains a Legacy Products section on their Technical Support page where MEDOC documentation or software links may occasionally appear.
For long-term reliability, it is highly recommended to migrate away from MEDOC 2.4:
. It will not run directly on 64-bit versions of Windows (Windows 7, 10, or 11). The Workaround melsec medoc 2.4 download
Converting your MEDOC programs to modern software ensures that younger engineering staff can easily troubleshoot the logic without needing to learn archaic DOS keyboard commands.
The MELSEC MEDOC 2.4 software remains a critical tool for automation engineers managing legacy manufacturing systems. Created by Mitsubishi Electric, this DOS-based software programming tool configures older MELSEC F, FX, A, and AnS series Programmable Logic Controllers (PLCs). : Mitsubishi Electric Americas maintains a Legacy Products
MEDOC (Mitsubishi Electronic Documentation) is an integrated software package used for programming, monitoring, and maintaining Mitsubishi PLCs.
Convert the logic into a modern format, allowing you to view and edit the code on Windows 10 or 11. The Workaround Converting your MEDOC programs to modern
To communicate with a physical PLC, DOSBox must map your modern USB-to-RS232 adapter to a legacy COM port. Open the dosbox.conf configuration file. Scroll down to the [serial] section.
While modern automation systems have moved far beyond DOS-based software, remains an essential, robust tool for ensuring the longevity of legacy Mitsubishi equipment. By setting up a virtual machine with Windows XP and ensuring correct serial communication, technicians can successfully manage these robust, older systems.
| Problem | Likely Solution | | :--- | :--- | | | This is a division by zero timing bug in old Borland Pascal compilers. Use a TSR patch like PATCH200 or run in DOSBox with appropriate core settings. | | Serial communication fails | MEDOC 2.4 expects COM1 at IRQ 4, address 3F8h. Ensure your USB-to-serial adapter emulates these standard settings. Use the SC-09 programming cable. | | File won't open | The .PLC file might be corrupt. Try opening with a hex editor to check for consistent data. Alternatively, use MEDOCSAVE and MEDOCLOAD utilities (if available). | | Screen glitches | DOSBox config: Set output=overlay or output=opengl . Disable hardware scaling. |
