| 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 |
| Error Message | Meaning | Fix | | :--- | :--- | :--- | | E-1001: Invalid address format | You typed X100 instead of X100.0 for a bit address. | Use dot notation for bits, no dot for words. | | E-2040: Subroutine stack overflow | Too many nested SUB 64 calls (max 8 levels). | Redesign logic; flatten subroutine hierarchy. | | E-5005: Connection refused (10061) | CNC is not listening on port 8193. | On CNC: SYSTEM > PMC > I/F > Embedded Ethernet > Enable . | | Cannot edit: PMC is in STOP mode | The CNC’s PMC is not executing logic. | Set PMC to RUN via CNC panel (safety key or soft key). | | Compile OK but symbols missing on CNC | You forgot to download the .CMT file. | Use PMC > Download > All (Ladder + Comments + Data). |

Signals sent from the CNC side to the PMC side (e.g., spindle speed reached).
: It allows for offline logic development, which can later be uploaded to the PMC, reducing machine downtime during commissioning.
