To understand Fapt Ladder, one must understand the PMC. Unlike the CNC side of the control, which calculates tool paths and axis movements, the PMC acts as the machine’s "brain" for auxiliary functions.
Industrial automation relies heavily on robust software to bridge the gap between human operators and complex machinery. For decades, FANUC has been a global leader in Computer Numerical Control (CNC) systems. At the heart of managing peripheral devices on a FANUC CNC—like tool changers, safety doors, and coolant systems—is the Programmable Logic Controller (PLC), which FANUC refers to as the Programmable Machine Controller (PMC).

If a source file is lost, the software can often upload the binary file directly from the CNC memory and reverse-engineer it back into a readable visual ladder diagram, provided the developer did not lock or strip out the symbol comments. Workflow: Creating and Transferring a Ladder Program To understand Fapt Ladder, one must understand the PMC
: Managing massive symbol files and comments can be tedious compared to the tag-based systems found in modern PLC software. 🏁 The Verdict Score: 4.0 / 5.0 For decades, FANUC has been a global leader
Internal signals sent from the PMC side back to the CNC side (e.g., feed hold command, cycle start authorization).
Internal signals sent from the CNC side to the PMC side (e.g., a G-code command like M03 active).
