FanucProgramManager
What This Is
Console EXE (C# .NET 4.7.2) for upload/download of CNC programs to/from machine controllers. Supports Fanuc FOCAS, Heidenhain LSV2, Siemens Sinumerik FTP, and Mitsubishi FTP. Runs on Windows, distributed to licensed machine operators and integrators.
Core Value
Machinists and operators transfer CNC programs to/from any controller without manual intervention or internet access.
Current State
| Attribute | Value |
|---|---|
| Type | Application |
| Version | 0.1.0 |
| Status | v0.1 complete — pending hardware testing |
| Last Updated | 2026-05-17 |
Requirements
Core Features
- Upload programs to CNC controller
- Download programs from CNC controller
- Local file management (organize/store programs on disk)
- Multi-CN brand support (Fanuc + others)
Validated (Shipped)
- Fanuc FOCAS upload/download — initial
- AES encryption for program files
- CLI argument parsing
- Machine-bound license check (hardcoded)
- Multi-CN support — Fanuc, Heidenhain, Siemens, Mitsubishi — Phase 1–4
- 3-file management mode (Fanuc) via IFanucMachine — Phase 4
- NC program validation before upload (all 4 manufacturers) — Phase 5
Planned (Next)
- Hardware fingerprint license system (CPU ID + disk serial + encrypted file)
- ReadActiveProgramAsync / SelectMainProgram for Heidenhain and Siemens
- Integration test against real hardware (Heidenhain, Siemens, Mitsubishi)
Out of Scope
- Cloud sync
- Web UI
- Internet-dependent license validation
Constraints
Technical Constraints
- .NET Framework 4.7.2 — max compatibility, no upgrade
- Fanuc FOCAS via
fwlib32(32-bit DLL, Windows-only) - Must run offline — no internet dependency at runtime
- License validation must work without network
Business Constraints
- Software must be license-protected (offline, machine-bound)
- Current approach: hardcoded machine check — needs improvement
- Target: hardware fingerprint + encrypted license file
Key Decisions
| Decision | Rationale | Date | Status |
|---|---|---|---|
| .NET 4.7.2 | Max compatibility with operator machines | 2026-05-13 | Active |
| Console EXE output | Simple deployment, scriptable | 2026-05-13 | Active |
| Offline license only | Operators may have no internet on shop floor | 2026-05-13 | Active |
# = Warning in Fanuc/Mitsubishi |
Macro variable indicator — valid in context | 2026-05-13 | Active |
| Constructor injection for validator | Internal ctor accepts mock — enables unit testing without Windows DLL | 2026-05-13 | Active |
| Heidenhain LSV2 port 19000 | Standard LSV2 port; needs real hardware verification | 2026-05-13 | Active |
Siemens FTP dir /_N_MPF_DIR/ |
Sinumerik standard MPF directory; FTP option must be enabled | 2026-05-13 | Active |
Success Metrics
| Metric | Target | Current | Status |
|---|---|---|---|
| Program transfer correctness | 100% (byte-verified) | Unknown | Pending hardware test |
| License validation (offline) | Works without network | Hardcoded | At risk — v0.2 target |
| Multi-CN support | ≥2 manufacturers | 4 (Fanuc/Heidenhain/Siemens/Mitsubishi) | Done |
| NC validation coverage | All manufacturers | 4 manufacturers, 30+ tests | Done |
Tech Stack / Tools
| Layer | Technology | Notes |
|---|---|---|
| Language | C# | .NET Framework 4.7.2 |
| UI | Console EXE | CLI args via InputArgs.cs |
| CN Protocol (Fanuc) | FOCAS fwlib32 | 32-bit DLL, Windows-only |
| CN Protocol (Heidenhain) | LSV2 over TCP | Port 19000, CRC-16/CCITT |
| CN Protocol (Siemens) | FTP (FtpWebRequest) | ASCII mode, passive, /_N_MPF_DIR/ |
| CN Protocol (Mitsubishi) | FTP (FtpWebRequest) | Port 21, /PRG/, no extensions |
| Validation | NcProgramValidator | Universal + per-manufacturer rules |
| Encryption | AES (AesCrypt.cs) | Program file protection |
| Licensing | Machine fingerprint | Hardcoded now, v0.2 target |
| Testing | NUnit 3.13.3 + Moq 4.18.4 | .NET 4.7.2 test project |
