First determine whether the failure is XML syntax, SCL structure, physical identity, edition handling, vendor-private content, broken references or a mismatch between the file and the running IED. When the source cannot be repaired safely, complete live discovery can provide a new bounded baseline.
Do not begin by deleting arbitrary XML sections. Record the parser location or rejected reference, the receiving tool and edition expectation, then compare the file with live IED evidence.
A file can be valid XML but unsuitable for a target configurator. It can also import successfully while representing an outdated device model, incorrect identity or incomplete reporting assignment.
Keep the original filename, edition, namespace, exact error message, reported location and receiving software version.
Trace physical IED name, AccessPoint, server, full Logical Device domains, DataSets, FCDA members, RCBs and communication references without blind deletion.
Confirm endpoint, complete typed model, DataSet directory, concrete RCB names and options currently exposed by the relay.
Repair or normalize the opened source when its relationships remain trustworthy. Otherwise generate Edition 2 IID or Edition 1 ICD from complete live discovery.
For a bounded gateway or legacy SAS path, audit availability and export exactly one verified RCB as an Edition 1 or Edition 2 CID baseline.
Generated SCL is vendor-neutral and schema-aware, but proprietary tools can apply rules beyond the standard. Retest the exact importer and preserve its result as project evidence.
Select the intended RCB, retain verified DataSet members and choose the required SCL edition instead of removing unrelated XML through trial and error.
Continue with live-model comparison, the IP-to-SCL workspace or the complete multi-vendor integration workflow.
ARSAS can expose live model, report, GOOSE, file, control and diagnostic evidence. Final conclusions still depend on the approved project design, vendor documentation, test procedure, network access and independent verification.
Reviewed 20 July 2026 for practical IEC 61850 laboratory, FAT, SAT, commissioning and troubleshooting use.
The current stable build includes Rev.3 IO List FAT import, an executive AS TESTED evidence report, a loaded Engineering/FAT workspace session, and direct receive-only GOOSE plus bounded SMV capture from each IED card.
Use the installer for a normal workstation, choose the portable single EXE for an approved no-install deployment, and verify the published SHA-256 before use.
