Validation Rules

Validation Rules

SCD Visualizer runs 26 structural checks plus XSD schema validation on every loaded file.

Issues are classified by severity:

• Error — violates a hard rule; must be fixed
• Warning — potential problem; review recommended

General IEC 61850 checks (IEC_001–008)

Standard structural rules applicable to any IEC 61850 SCD file.

Code	Severity	Description
IEC_001	Warning	GOOSE subscription (ExtRef) not resolved to a known publisher dataset
IEC_002	Warning	SV subscription (ExtRef) not resolved to a known publisher dataset

IEC_006	Warning	LN lnType reference has no matching DataTypeTemplates entry
IEC_007	Warning	GSEControl or SampledValueControl dataset contains no FCDA entries
IEC_008	Error	confRev attribute is zero or missing on a control block

XSD schema validation (SCL_XSD_001)

The full IEC 61850-6 XML schema is validated using xmllint-wasm. The SCL edition is auto-detected:

Header version/revision	Schema used
2007 / B	Edition 2 (2007B)
2007 / B4	Edition 2.1 (2007B4)

Schema issues are reported as SCL_XSD_001_<line> with the exact xmllint error message.

Waiving checks

In the Issues view, individual check codes can be waived. A waived check is excluded from the issue count in the top bar and from the health gauge. Waived codes are stored in localStorage per browser session.

To waive a check: click the waive button on any issue row in the Issues List view.

Configuring thresholds

Edit validation_config.json at the project root to adjust LNET_010–013 thresholds:

{
  "goose": {
    "vlan_priority_min": 4,
    "min_time_ms": 2,
    "max_time_ms": 1000
  },
  "sv": {
    "vlan_priority_min": 4
  }
}
