The trace view — a Modbus RTU session decoded in real time.

What it does

Twelve protocols decoded

Modbus RTU/ASCII/TCP, DLMS/COSEM, M-Bus, IEC 62056-21 and MASS fully parsed with request/response pairing; DNP3, BACnet MS/TP, HART, IEC 60870-5-101/103 and PROFIBUS decoded to frames.

Byte-accurate tracing

Real-time capture with timestamps, filtering and search, and ten display modes from ASCII and HEX to decimal and binary. Export to CSV, BIN, TXT or HTML.

Frame builders

Compose Modbus, M-Bus and DLMS requests with automatic CRC, LRC and FCS calculation.

Online device library

A GitHub-backed library of Modbus register maps, verified with SHA-256, so readings arrive with names and units instead of raw registers.

Automation & AI

Visual flow automation with Python scripting, plus an embedded Model Context Protocol server that lets AI assistants drive the bus.

Remote serial over SSH

Reach serial ports on edge devices over SSH and work with remote buses as if they were plugged in locally.
