FANUC LADDER系列软件经历了多个版本的迭代，主要包括：
If you are currently working through a specific automation project or troubleshooting an active alarm,g., 0i-F, 31i-B).
Real-time visualization of high/low bit states (X, Y, R, F, G registers) while the machine is running. PMC Signal Trace: fanuc ladder iii 9.5
Use the shortcut toolbar to drop Normal Open (NO) contacts, Normal Closed (NC) contacts, and output coils.
Two or more rungs are writing execution states to the exact same memory address (e.g., Y0.1). Two or more rungs are writing execution states
Used for delays, such as waiting for a hydraulic pump to build pressure before allowing an axis to move. Version 9.5 supports both fixed timers and variable data table-driven timers. SUB 23 (CODB) - Binary Code Conversion

FANUC LADDER‑III is the industry‑standard programming system for developing, diagnosing, and maintaining sequence programs for FANUC’s built‑in PLC, the Programmable Machine Controller (PMC). Available to run on a standard PC, it has become an indispensable tool for automation engineers, CNC programmers, and machine tool technicians.

For developers who do not have physical access to a CNC machine tool during the initial coding phase, Version 9.5 integrates seamlessly with FANUC's NCGuide or its standalone internal simulator. The simulator clones the target hardware's execution engine, allowing developers to manually toggle X or F inputs and watch how the Y and G outputs react, ensuring logic validation before deployment to actual factory floors.
