Overview — what “MELSEC MEDOC 2.4” refers to

MELSEC MEDOC (sometimes “MEDOC Plus”) is older Mitsubishi Electric PLC programming software used to communicate with and program MELSEC family PLCs (commonly A-series/A1, FX and some earlier FX variants). Version numbers commonly cited in forums and reseller listings include DOS-era 2.40 (often written 2.4 or 2.40) and a Windows FX-specific package (FX 1.x / FX-PCS/WIN). MEDOC 2.40 is typically a DOS application or early Windows-era utility distributed historically on CD with Mitsubishi PLCs or sold by authorized resellers.

Code Migration: To upgrade an old PLC to a modern FX5U or iQ-R series, you often need to first extract the code using MEDOC and then convert it through GX Developer.

MELSEC MEDOC (Mitsubishi Electric Documentation) is the original DOS-based programming software for Mitsubishi Electric’s MELSEC-F and MELSEC-A series Programmable Logic Controllers (PLCs). Version 2.4 represents one of the final and most stable iterations of this software before Mitsubishi transitioned to the Windows-based GX Developer and GX Works platforms. Key Features
