Open SCL Studio's sample 132/33 kV substation, trace every GOOSE and report from publisher to subscriber, and generate the point-to-point test sheet for the SCADA signals.
| File | S13_Sample.scd (click Sample in SCL Studio), SCL 2007 B4, Edition 2.1 |
| IEDs | P132_Q01 line distance protection, P87T_T1 transformer differential, GW1 station gateway |
| Network | StationBus, 8-MMS, 100 Mb/s, IP 10.13.1.11 / .21 / .200 |
The overview counts the model and runs the semantic checks.

|---|---|---|---|
| Semantic validation | No errors | 0 errors, 0 warnings | ✓ PASS |
| GOOSE addresses unique | MAC and APPID unique on the subnetwork | 0011 and 0021 | ✓ PASS |
| Every report has a client | ClientLN present | GW1 for both | ✓ PASS |
| FAT sheet | One line per SCADA signal | 5 signals | ✓ PASS |
Key insight: Generating test sheets from the SCD means the test covers exactly what is configured — no signal is missed, and none is tested that does not exist.
Every input in this example is editable in the live calculator — no signup needed.
Open IEC 61850 SCL Editor (SCL Studio) calculator →Yes. Choose GOOSE and SV in Test sheets to list every subscribed signal, and use GOOSE capture to check a Wireshark capture against the SCD.
The unbuffered report sends all data-set values every 5 s even if nothing changes, so the gateway always has a recent value.
