If you work with FANUC CNCs, you know that the PMC (Programmable Machine Controller) is the brain behind the brawn. While the G-code handles the cutting, the PMC handles the logic—the interlocks, the tool changers, the alarms, and the safety gates.

: Integration with NCGuide allows users to test their ladder programs on a PC before ever loading them onto a physical machine, preventing costly crashes or hardware damage. If you work with FANUC CNCs, you know
| Address Type | Mnemonic | Description | Example | |--------------|----------|-------------|---------| | | X | Physical inputs from machine switches/sensors (to PMC) | X2.3 = Limit switch | | Digital Output | Y | Physical outputs from PMC to machine relays/valves | Y3.1 = Coolant pump relay | | Internal Relay | R | Internal logic flags (non-physical) | R100.0 = Tool clamp request | | Keep Relay | K | Retentive, user-configurable options | K1.0 = Enable auto-restart | | Timer | T | On-delay or off-delay timers (8- or 16-bit) | T10 = 2.5 sec dwell | | Counter | C | Up/down counters | C5 = Part count | | Data Table | D | General-purpose word/byte storage | D200 = Spindle speed override value | | CNC->PMC Message | F | Status signals from CNC (axis moving, in cycle, etc.) | F45.3 = Servo ready | | PMC->CNC Command | G | Commands from PMC to CNC (start cycle, tool change, etc.) | G8.4 = Cycle start | | Address Type | Mnemonic | Description |
Newer FANUC hardware supports "Function Blocks" (FB) that allow for modular programming. Version 9.5 is required to unlock and edit these advanced structures.
: This version resolved critical issues where the application would unexpectedly terminate during a "General Search" or "Advanced Search" in ladder programs containing an excessive number of subroutines.
