Read without hiding the protocol
Create source views for coils, discrete inputs, holding registers, or input registers. Busloom shows both the documentation notation and the zero-based PDU address, while Raw Traffic preserves function codes, TX/RX bytes, timings, exceptions, and malformed responses.
- FC01, FC02, FC03, and FC04 reads
- FC05, FC06, FC15, and FC16 writes
- RTU, TCP, and Modbus/TCP Security (TLS)
- Decoded values beside original words and bits
Turn a successful read into a reusable project
Connection profiles, views, tags, trends, import presets, and automation are stored in a reviewable .busloom.json file. Live samples and traffic remain session data until you explicitly record or export them.
Use the same evidence when something goes wrong
Connection Health separates protocol exceptions from timeouts, CRC failures, and transport errors. Auto Scan finds readable ranges; Register Inspector proves byte order and scaling; Replay opens a saved capture without reconnecting to the device.
