A professional PySide6 CANopen bus monitor and simulator.

canopen-utils

A professional, live CANopen bus monitor and device simulator built with PySide6, python-can, and canopen.

Features

canopen-inspect

A live CANopen bus monitor that connects to hardware, loads EDS files, and translates raw CAN traffic into human-readable data in real-time.

• Connection Manager: Select CAN interface and bitrate.
• Node Radar: Automatically detect active nodes on the bus via Heartbeats, and allow assigning an EDS file to them. Send NMT commands (Start, Stop, Pre-Op) to individual nodes or broadcast.
• Live TPDO Dashboard: A table showing real-time updating values translated by the EDS.
• SDO Explorer: A tree view to browse the Object Dictionary and perform acyclic read/writes.
• Traffic Trace: A rolling log view translating raw hex CAN frames into human-readable object names on the fly.

canopen-sim

A companion simulator that behaves like a real CANopen hardware node.

• Automatically enters PRE-OPERATIONAL and sends a 1Hz Heartbeat.
• Generates TPDOs according to a configurable simulated physics engine.
• Responds to NMT commands and SDO requests over the bus.
