IEC 61850 Process Bus visibility for engineers who need defensible answers.Analyze live Sampled Values, GOOSE, PTP timing context, and SCL expected-vs-observed evidence. Reproduce sanitized classic PCAP captures through the same decoder path while keeping timing and evidence limitations visible. Stable v1.4.2 · Windows 10/11 x64 · Free and open source desktop_windows Windows 10/11replay PCAP replayshield No transmit path hub Process Bus Insight Analyzer ready  fullscreen Previewdownload Latest stable release Get the latest stable Windows installer.Stable v1.4.2 · self-contained Windows x64. Installs over your previous version; Npcap is separate for live capture. auto_awesome Capabilities From packet observation to scoped engineering evidence.The application shortens the path from traffic to a reviewable finding without treating software capture as certified metrology. GOOSE inspectionStable keyed Sources, a decoded event timeline, Follow live, minimal red unread dots, one shared acknowledgement state, and exact signal-change tooltips. PTP contextTiming traffic and freshness with explicit timestamp-source limits. SCL comparisonCompare observed traffic with SCD, ICD, or CID expectations. PCAP replayReproduce sanitized classic Ethernet captures through the live decoder path. Receive-onlyNo SV or GOOSE publishing and no IEC 61850 control-command path. route Engineering workflow Keep expected, observed, interpreted, and externally proven behavior separate.TAP, mirror port, or controlled engineering switch. Identify stream, publisher, VLAN, APPID, timing context, and capture health. Load SCL expectations or reproduce sanitized traffic offline. State what was expected, observed, decoded, and not proven.  fullscreen Previewgavel Licensing GPL community edition with a separate negotiated commercial path.Post-transition source and packages are GPL-3.0-or-later only. Historical Apache-2.0 grants remain attached to the revisions and artifacts to which they originally applied. Community editionUse, study, modify, and redistribute under GPL-3.0-or-later and its conditions. Historical boundaryApache-2.0 ends at Commercial discussionProprietary integration, OEM/white-label, closed-source redistribution, private branches, or contractual services require a separate commercial agreement. The notice grants no additional rights by itself. help Boundaries Important questions before field use.security Does it control equipment?No. It is receive-only and does not publish SV/GOOSE or send IEC 61850 control commands. timer Can it prove certified timing?No. Ordinary Windows/Npcap and replay timestamps are screening evidence, not calibrated timing proof. verified Does a matching screen prove IED acceptance?No. External IED reception, trust, and process action require separate evidence. workspace_premium Can a company obtain proprietary rights?A separate commercial agreement may be negotiated for rights controlled by the project owner. The repository notice is not itself a commercial license. |
