Extract the raw binary code from physical IC chips (e.g., 27C256, 27C512).
EPROMs only store the functional logic, not the descriptive comments or labels (e.g., it stores X000.0 , but not the label "Cycle Start Button"). After conversion, you will have a working ladder, but it will be unannotated. You must use old paper electrical schematics to manually re-enter comments. Fanuc Pmc Eprom Convert Tool
Select the appropriate EPROM type and series, which corresponds to the physical chip removed from the Fanuc board (e.g., 27C256, 27C512). Load the File: Load the raw binary file created in step 1. Extract the raw binary code from physical IC chips (e
Joins data from two separate EPROM chips (OE1/OE2) into a single sequence program file for editing. How the Workflow Works Extraction: Use a hardware EPROM reader or the CNC's PMC Maintenance screen to backup the "Handy File" to a memory card or USB. Conversion: LADDER-III software , select "Import," and choose the Handy File Restoration: You must use old paper electrical schematics to
