TDC3000 Reverse Engineering Consulting
Even with minimal or outdated documentation, we provide a full, accurate picture of your TDC3000 system (LCN, AM/APM, CL programs, point database) through our structured consulting process.
Our Step-by-Step Consulting Process
- Full system backup (GUS, LCN, AM/APM, CL programs, point database)
- Document all LCN nodes, AM/APM modules, and I/O mappings
- Extract and catalog Control Language (CL) programs and point configurations
- Create cross-reference reports for every point and logic block
- Build plain-English functional specification for each major process area
- Map legacy points to modern descriptive tags and data structures
- Develop phased migration roadmap and cutover guidance
