Once converted, the ladder logic can be printed, annotated, and studied. This is impossible with a raw EPROM binary.
Use a hardware EPROM programmer (e.g., Data I/O, Needham’s, or a TL866) to read the physical 27C256, 27C512, or similar chip. Save the file as machine.BIN . Fanuc Pmc Eprom Convert Tool
: It allows you to use standard, commercially available EPROM readers/writers instead of Fanuc-specific models. Once converted, the ladder logic can be printed,
The EPROM chip is removed from the CNC and read using a universal programmer. The resulting binary file is then processed by the Fanuc PMC EPROM Convert Tool. Save the file as machine
| Tool Name | Type | Best For | Price Range | | :--- | :--- | :--- | :--- | | | Hardware (USB) | Reading all vintage EPROMs | $150 | | FANUC Ladder Editor Pro V7 | Software (Official) | Direct conversion to KLC | $2,500 | | PMC Image Tool by TechTransfer | Software (3rd Party) | Obscure PMC-L/M models | $800 | | MULTIPROM Emulator | Hardware Emulator | Replace EPROM with RAM | $600 |
You want to retrofit a Fanuc 0i-MF control but keep the original ladder logic. Conversion tools let you export the old PMC to a format compatible with the new hardware.
Several industrial automation specialists have developed standalone converters. These are popular for older series (0, 6, 11, 12, 15).
