Ensure all internal variables, interlocks, and emergency stop circuits are correctly evaluated before applying changes to live hardware.
These courses are available from FANUC Academy locations worldwide and are typically aimed at electricians, maintenance technicians, and PMC programmers.
: Choose the correct PMC model (e.g., 31i-A, 31i-B, 0i-F) to ensure instruction compatibility.
Launch FANUC Ladder-III and select . Choose the specific PMC type that matches your target CNC hardware (e.g., PMC-SB7, PMCi-A). Selecting the wrong PMC model will result in compilation errors due to differences in memory allocation and supported functional commands. Step 2: Configuring I/O Link

FANUC LADDER-III offers a robust suite of features that cover the entire lifecycle of a PMC program, from initial development to ongoing maintenance.
Output signals from the PMC side to the CNC (feed hold, cycle start command).
Windows 11 was officially supported via a patch in late 2021 (Service Pack 1 for LadderIII). Ensure you have version LadderIII V8.90P or higher. Step 2: Configuring I/O Link F8 : Functional
With each new release, FANUC adds support for new CNC models, enhances security features, and adds new function libraries, ensuring that LADDER-III remains a modern, capable tool for the global machine tool industry.
Once connected:
FANUC continues to develop and update LADDER-III, with newer versions (such as V9.5 and V9.9) adding support for later Windows operating systems, including Windows 10 and Windows 11, and compatibility with the latest FANUC CNCs, including the 0i-F Plus, 30i-B Plus, and 31i-B5 series.
The 2021 version includes a preview of the ROT function. Before downloading, you can enter test values and see the direction output without a CNC.
