What was engineered or exported
- IED and AccessPoint definitions
- communication addressing
- Logical Device and DataType templates
- DataSets, RCBs and GOOSE intent
- vendor-private engineering context
Configured intent · running model · drift
The SCL file and the live relay answer different questions.
SCL describes configured engineering intent. Live MMS discovery shows what the connected IED currently exposes. Troubleshooting becomes stronger when both are compared without treating either one as complete proof by itself.
What the server exposes now
- reachable endpoint and association behavior
- Logical Devices, Nodes, objects and attributes
- current DataSet and RCB inventory
- live value, quality and timestamp evidence
- supported service and access outcomes
Diagnostic path
Compare the items that affect the failed workflow.
A full-file textual difference can create noise. Focus on endpoint, model reference, DataSet membership, RCB association, GOOSE identity or control model related to the observed problem.
Identify the authoritative project file
Record filename, source, revision and intended target before comparing it with live evidence.
Discover the running server model
Use the approved endpoint and retain the association and model timestamp context.
Compare functional references
Check the exact object, DataSet, RCB or GOOSE reference required by the test.
Resolve drift through engineering process
Update the controlled project baseline or device configuration only through the approved owner and procedure.
Use live evidence to prepare a controlled baseline
ARSAS can retain verified DataSet members and selected RCB context while keeping the source SCL and live model visible.

Use the CID rejection guide for parser problems or silent reporting for report mismatch.
Use the evidence to narrow the cause—not to claim conformance.
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.
