What do I need before running Process Bus Insight?

Use a Windows 10 or Windows 11 PC, install Npcap when raw packet capture is required, and connect to the Process Bus through a safe capture path such as a TAP, mirror port, or engineering test switch.

Does it send commands to relays or merging units?

No. Process Bus Insight is receive-only and raw-passive. It listens to network traffic and does not publish GOOSE, publish SV, or send IEC 61850 control commands.

Can I use it without an SCL file?

Yes. Live traffic visibility works without SCL. Loading SCD, ICD, or CID files adds expected-vs-observed validation for APPID, VLAN, MAC, dataset, confRev, and stream identity.

Focused features for substation automation engineers.

The interface shortens the path from live packet capture to usable engineering evidence. It keeps capture limitations visible and avoids pretending that Windows software capture is certified metrology.

Sampled Values visibility

View SV stream identity, APPID, svID, VLAN, source MAC, continuity state, phasor, waveform, and metering context.

GOOSE inspection

Inspect publishers, state changes, stNum, sqNum, typed dataset values, and event history in a cleaner engineering view.

PTP context

Confirm timing traffic presence, transport context, and confidence wording while keeping software timestamp limits explicit.

SCL expected-vs-observed

Load SCD, ICD, or CID files to compare APPID, VLAN, MAC, DataSet, confRev, and stream identity against live traffic.

Capture clearer findings for FAT, SAT, commissioning review, and practical troubleshooting discussion.

shield

Receive-only boundary

The application listens and decodes. It does not publish GOOSE/SV traffic and does not send control commands.

route Field workflow

A practical path from network traffic to engineering conclusion.

01 Connect through a safe capture path

Use a TAP, mirror port, or controlled test switch. Avoid inserting unknown tools into protection-critical paths.

02 Observe live SV, GOOSE, and PTP

Identify what is alive first: publisher, VLAN, APPID, stream identity, timing traffic, and basic behaviour.

03 Load SCL when available

Move from traffic exists to traffic matches engineering expectation with expected-vs-observed checks.

04 Document the finding

Use clear wording for what was expected, what was observed, and which object needs attention.

help FAQ for engineers trying the app

What users usually need to know before download.

computer What do I need before running it?

A Windows 10 or Windows 11 PC, a safe network capture path, and Npcap when raw Ethernet capture is required. For real Process Bus testing, use a TAP, mirror port, or controlled test switch.

science Can I use it during FAT, SAT, or commissioning?

Yes. It is designed for visibility, troubleshooting, and engineering evidence during lab validation, FAT, SAT, and commissioning. It helps explain what is observed on the network.

security Does it control relays, merging units, or bay controllers?

No. It is receive-only and raw-passive. It does not publish GOOSE, publish Sampled Values, or send IEC 61850 control commands.

description Do I need an SCL file?

No for live visibility. Yes for deeper expected-vs-observed validation. Loading SCD, ICD, or CID files allows the app to compare live traffic against engineering configuration.

network_check Why can I see no traffic?

Most cases are capture-path issues: wrong adapter, missing Npcap, switch port not mirrored, VLAN not forwarded, or the PC is connected to the wrong network segment.

timer Can it prove certified timing performance?

No. Windows software timestamps are useful for screening and troubleshooting, but certification-grade timing proof needs validated test equipment and hardware timestamping.

workspace_premium Is it free for professional use?

Yes. Process Bus Insight is free and open source under Apache-2.0. There is no subscription, license key, or trial limit.
