Bailey INFI90 Reverse Engineering Consulting
Even with minimal or outdated documentation, we provide a full, accurate picture of your Bailey INFI90 system (INFI 90, OIS, operator stations, and control modules) through our structured consulting process.
Our Step-by-Step Consulting Process
- Full system backup (INFI 90 nodes, OIS, control modules, and point database)
- Document all INFI 90 hardware, communication links, and I/O mappings
- Extract and catalog control logic blocks and configuration files
- Create cross-reference reports for every point and logic block
- Build plain-English functional specification for each major process area
- Map legacy points and blocks to modern descriptive tags and data structures
- Develop phased migration roadmap and cutover guidance
