See SnapPLC in action.
Upload any PLC cabinet photo and watch the analysis run in real time.
From photo to fault in five steps.
Snap the Cabinet
Take a clear photo of your PLC rack, control panel, or enclosure. Any angle, any lighting.
AI Identifies Hardware
YOLO-PLC detects every module, power supply, and terminal block — across 500+ part numbers.
LED State Analysis
Our color model reads every indicator light and maps it to known fault codes and run states.
Ladder Logic Inference
System infers probable ladder logic rungs from detected I/O configuration and wiring topology.
Fault Report Delivered
Plain-English diagnostics with severity tags, root cause assessment, and recommended next steps.
Built for the plant floor, not the board room.
Hardware Recognition
Identifies 500+ PLC module types across Allen-Bradley, Siemens, ABB, Mitsubishi, and 40+ other manufacturers. Detects slot position, part number, and firmware tier.
I/O Topology Mapping
Reconstructs digital and analog I/O maps from wiring and label analysis. Full topology export to CSV and L5X.
Ladder Logic Inference
Infers probable ladder logic rungs from hardware configuration, LED state patterns, and detected I/O relationships.
Fault Correlation Engine
Cross-references active fault LEDs against 12,000+ known module behaviors to isolate root cause in seconds.
Protocol Detection
Identifies communication protocols in use: EtherNet/IP, PROFIBUS, Modbus TCP, DeviceNet, CC-Link, and PROFINET.
Change Detection
Compares cabinet photos over time to flag undocumented hardware changes. It noticed someone added a relay. No one told us.
AI-reconstructed ladder diagram.
Inferred from detected I/O configuration and LED state patterns.
What the floor is saying.
"It blamed the controls engineer before production even called."
"Operator Mode predicted Dave would press Reset six times. Dave pressed Reset seven times."
"Told me the E-Stop was physically damaged. Turned out it was just zip-tied shut. Four stars because it was technically correct."
"It found logic we didn't even know was running."
