Sampled Values Profile Support
ARSVIN is an IEC 61850 Sampled Values publisher for lab and engineering use. It is not an accredited conformance test tool and not a calibrated merging unit.

Publisher-only evidence features
ARSVIN can export generated SV frames to PCAP for offline verification. The export path creates frames from the configured publisher plan and writes them to disk; it does not sniff or analyze traffic from the process bus.
Quality field presets are available for intentional relay-behavior tests:
- good
- invalid
- questionable
- oldData
- test
- operatorBlocked
Use non-default quality presets only in isolated lab tests and document the intent in the FAT/SAT notes.
TX Timing Health
ARSVIN reports publisher-side timing health while publishing. This is local TX-loop measurement only; it does not capture live process-bus traffic.
| Metric | Meaning |
|---|---|
| Target FPS | Expected Ethernet frame rate after nofASDU packing. |
| Actual FPS | Frame rate observed by the local publisher loop. |
| Jitter avg/max | Difference between actual frame interval and target interval. |
| Late frames | Frames that started sending later than the local threshold. |
| Missed schedule | Frames that were late by more than one target interval. |
| Send avg/max | Duration around the local transport send call. |
Timing Health is intended to make Windows/Npcap limitations visible. It is not a claim of IEC/IEEE 61850-9-3 timing compliance.
