To understand the Convert Tool, one must first understand the problem. On older Fanuc series (0, 6, 11, 15, and early 16/18), the PMC ladder logic was burned onto physical EPROM chips (typically 27256, 27512, or 27C010). These chips were seated on a PMC-MOD board inside the CNC cabinet. Editing a ladder required a dedicated EPROM writer, ultraviolet erasers, and a deep understanding of hexadecimal addressing. The was a software utility (usually running on MS-DOS or early Windows 95/98) that acted as a translator. It took raw binary dump from an EPROM and converted it into a file format that Fanuc’s programming software—such as FAPT Ladder or FLADDER —could understand. Fanuc Pmc Eprom Convert Tool
