IndAutomation: AI-Powered PLC and VFD Fault Diagnosis Database
These articles are AI-generated summaries. Please check the original sources for full details.
313 PLC Fault Codes in One AI Database — Free to Query
RepairXpert has launched IndAutomation, an AI-driven fault diagnosis tool covering 313 specific error codes across major industrial hardware. The system provides real-world fix procedures and “field tricks” for hardware from Allen-Bradley, Siemens, ABB, Mitsubishi, and Fanuc.
Why This Matters
Industrial technicians frequently encounter critical equipment failures during off-hours when official manufacturer support is unavailable. This tool bridges the gap between theoretical manual definitions and practical field troubleshooting by ranking causes by real-world frequency and providing instant access to proprietary field knowledge.
Key Insights
- Database includes 313 fault codes across manufacturers like Allen-Bradley, Siemens, ABB, Mitsubishi, and Fanuc (Source: RepairXpert, 2026).
- Fault diagnosis ranks probable causes by real-world frequency rather than just providing manual descriptions.
- Integration with Claude Code via an MCP server with 8 tools allows developers to diagnose faults directly in the terminal.
- The system provides practical “field tricks,” such as checking for clogged filters for motor overtemp A081 alerts.
- Pro and Enterprise tiers offer advanced features including photo analysis of fault screens and API access.
Working Examples

- VFD Troubleshooting: Technicians use the ‘loose connection trick’ for PowerFlex 525 F002 overcurrent errors. Pitfall: Replacing hardware before verifying physical terminal connections.
- Integrated PLC Debugging: Software engineers use the MCP server in Claude Code to query fault logic while writing control code. Pitfall: Neglecting physical environmental checks that software-only diagnostics cannot identify.
