This tool is often not an official Fanuc product but rather a third-party utility developed by specialized CNC technicians.
Insert the chips into a universal hardware ROM programmer (such as a Wellon, XGecu T56, or TL866II Plus).
To modify a ladder on an old PMC (e.g., PMC-L or PMC-M), you previously needed a FANUC Handy File or a PROM writer. Convert tools allow you to disassemble the EPROM image into a standard KLC or LAD file for editing on a PC.
Modern Fanuc controls utilize Flash ROM or FROM modules, which can be programmed directly via memory cards (PCMCIA or CompactFlash) or Ethernet. The conversion tool bridges the gap, allowing legacy logic to be compiled into modern memory formats. Types of Fanuc PMC Formats Covered Fanuc Pmc Eprom Convert Tool
Start a new project matching the exact CNC control model and PMC type (e.g., PMC-M, PMC-N, PMCQ).
The Fanuc PMC EPROM Convert Tool is an invaluable asset for CNC service engineers, retrofitters, and maintenance departments. By providing a technical bridge between physical legacy hardware components and modern digital editing software, it ensures that valuable machine logic can be preserved, modified, and carried forward into the future of manufacturing.

Instructions for without special tools.
Turn off the CNC machine completely. Locate the master PCB or PMC module and safely remove the EPROM chips using an IC extractor tool to avoid bending the pins.
Convert from EPROM binary to .LAD (Machine Ladder) for PMC models: SA1, SA2, SA3, SB3, SB4, SC, SD.
Run a check. Legacy systems often use older formatting rules or obsolete system relays. The compiler will flag any unsupported instructions. This tool is often not an official Fanuc
The tool allows for the modification of PMC data without needing a physical, functional machine to edit the ladder.
Select the source system type (e.g., Fanuc Series 0 PMC-M) and the target system type (e.g., Series 30i PMC-SB7). Step 3: Import and Convert
The Fanuc PMC EPROM Convert Tool provides a free, validated method for preserving legacy FANUC ladder logic. Future work includes implementing a graphical diff tool for two EPROM versions and adding support for encrypted PMC-N2 formats. Convert tools allow you to disassemble the EPROM
