Browse, monitor, and subscribe to industrial automation data right from your terminal. Keyboard-driven with mouse support. No bloated GUI, no complex setup, no license fees. Why opcilloscope? Traditional OPC Clients opcilloscope ------------------------ -------------- Heavy desktop apps Single self-contained executable Minutes to install curl \\ bash and you're running Resource-hungry GUIs Terminal-native interface Windows-only Windows, Linux, macOS (x64 & ARM64) Click-heavy workflows Keyboard-driven, mouse support Use cases: commissioning (verify PLC tags), troubleshooting (live values during fault diagnosis), integration testing (validate OPC UA server configs), recording (export to CSV for reports). Features - Browse — Lazily explore the OPC UA address space. Expand only what you need. - Monitor — Subscribe to variables with Enter . Receive OPC UA monitored-item notifications instead of polling values. - Inspect — Full node attributes: Description, DataType, AccessLevel, ValueRank. - Scope — Real-time multi-signal oscilloscope (up to 5 signals, 30 s sliding window). - Record — Export selected monitored variables to CSV. Notifications are queued with full-precision, locale-independent values (ISO 8601 UTC timestamps, . decimal separator, arrays as semicolon-joined elements). A bounded queue protects the UI if storage falls behind, and any dropped records are reported when recording stops. - Configure ","default_branch":null,"files":null,"tree":[],"storefront":"/r/SquareWaveSystems","claimed":false,"request_supported":{"post":"https://gitbuyer.com/r/SquareWaveSystems/opcilloscope/request-supported","requests":0},"note":"indexed from public GitHub; nothing is for sale on this page.
