FANUC LADDER-III is the official PC-based programming system used to develop, diagnose, and maintain ladder sequence programs for the Programmable Machine Control (PMC) , which is the integrated PLC within FANUC CNC systems. FANUC America Key Capabilities As of 2021, the software (specifically versions like ) focuses on the following core functions: Program Creation & Editing
: Develop ladder sequence programs for a wide range of FANUC CNC models. Monitoring & Debugging
: Real-time monitoring of PMC signal status, signal tracing, and online diagnostics via Ethernet connection to the CNC. Simulation Integration : Works alongside
(or CNC GUIDE) to simulate machine behavior on a PC without needing physical hardware. Maintenance
: Allows for writing programs to Flash-ROM and managing function blocks for modular code development. FANUC America Support and Documentation
For users looking for guidance in 2021, the standard reference manual is the GE Fanuc Ladder III (66234EN)
, which details setup, mnemonic editing, and compilation processes. Training and Resources When you first launch LadderIII 2021, the interface
Several platforms offer structured learning for this software: FANUC Academy
: Provides courses on PMC ladder programming, covering I/O Link devices and advanced functions like Macros. Online Courses : Platforms like
offer step-by-step tutorials for creating projects from scratch. Community Forums : Technical discussions on forums like address specific user queries such as opening PLC files or using specific functions like Ladder Iii - Fanuc - cccp3d.ru
Once connected:
Insert a network (F7). Build a self-holding circuit for the tool call:
Network 1: Tool Call Request Latch
|---[ ]---( )---|
| M100 (Call) | R100.0 (Request)
|---[ ]---( )---|
| R100.0 | R100.0
Using the new Auto-Address Validation, as you type X4.2 (Tool clamp sensor), the 2021 version highlights it green if valid, red if out of range. This eliminates syntax errors before compilation.
The user opens the project. They can add contacts, coils, and functional instructions (like timers TMR or counters CTR).
FANUC LADDER-III is the standard PC-based development software used to create, edit, and manage Programmable Machine Control (PMC)
sequence programs for FANUC CNC systems. The 2021 context typically refers to Version 9.x, which introduced modern enhancements like Unicode support and expanded comment capacities to improve documentation for complex industrial automation. FANUC America Core Functionalities
FANUC LADDER-III serves as a comprehensive Integrated Development Environment (IDE) for PMC programmers: Program Development
: Users can create, display, edit, and print ladder sequence programs using standard relay logic. Monitoring & Debugging
: The software allows for real-time monitoring of PMC signals and signal tracing to troubleshoot logic errors on the shop floor. Connectivity
: It connects directly to the CNC via Ethernet, enabling seamless program transfers and "online" monitoring where changes can sometimes be made while the machine is running. Simulation Integration : It works in tandem with Once connected: Insert a network (F7)
, FANUC’s simulation software, allowing developers to test ladder logic on a virtual CNC before deploying to physical hardware. FANUC America Key Technical Features (2021/v9.x Enhancements)
Recent iterations have focused on increasing the depth of documentation and ease of use: Expanded Comment Support : Modern versions support address comments up to 120 characters
(up from 16 or 80 in older versions), allowing for detailed descriptions of sensor and actuator functions. Multi-Language Documentation : Implementation of Unicode support
allows for comments and documentation in various global languages. Subroutine Management
: The software handles complex structures with a main program (first and second-level ladders) and numerous subprograms called between functional instructions like Advanced Printing & Export
: Enhanced print dialogs include options for landscape orientation, rung numbers, and direct PDF exports with comments for maintenance manuals. Industrial Monitor Direct Program Structure & Workflow
A typical development workflow in LADDER-III follows these steps: Project Creation
: Setting the PMC type (e.g., PMC-D, PMC-N) to match the CNC hardware (e.g., Series 30i, 0i-F). Logic Entry
: Programming rungs using contacts, coils, and functional instructions (timers, counters, data moves). Signal Naming
: Assigning symbolic names (comments) to I/O addresses (X, Y, G, F, R) to make the code readable. Compilation
: Converting the ladder logic into a format the CNC can execute. Deployment : Writing the compiled program to the CNC's via Ethernet or memory card. Maintenance and Troubleshooting Tips Subroutine Copying
: When moving logic between machines, it is critical to maintain bit names and prevent duplicate outputs (coils) to avoid unexpected machine behavior. Export for Documentation
The software integrates a robust I/O Module setup screen. The 2021 version includes updated libraries for newer I/O Link i and I/O Link I modules. It automates the allocation of addresses, reducing the manual calculation required when adding new relay boards or servo amplifiers used as I/O slaves.
