MMS discovery and reporting
Association, live IED directory, Functional Constraints, typed reads, DataSets, RCB planning, GI, monitoring, and evidence.
IEC 61850 · .NET 8 · GPL-3.0-or-later
IEC 61850 engineering tools for people who need protocol evidence.
ARIEC61850 combines an MMS client, guarded IED control, reporting, GOOSE, Sampled Values, SCL, PCAP diagnostics, simulation, CLI automation, and focused Windows engineering applications.
Validation boundary: a guarded command path has been exercised with a laboratory IED. Formal conformance, broad interoperability, and operational-substation approval are not claimed.
Guarded IED control
Control object LD0/CSWI1.Pos
Model Discovered from the IED
Status OPEN / CLOSED
Sequence Direct or SBO
Completion MMS / CmdTerm
Operator action OPEN or CLOSEControl-model-aware workflow
OPEN and CLOSE for operators. Typed IEC 61850 sequencing underneath.
Select a control Data Object such as CSWI.Pos. ARIEC61850 discovers the live control model and MMS type, then applies Direct Operate or Select-Before-Operate sequencing without asking the user to manually write Oper, SBO, or SBOw.

Engineering stack
One source tree for station-bus and process-bus investigation.
GOOSE and Sampled Values
Frame codecs, SCL-backed profiles, bounded publishing, subscription, PCAP inspection, sequence supervision, and diagnostics.
SCL and commissioning evidence
Expected-vs-observed engineering profiles, readiness checks, deterministic simulation, Markdown/JSON reporting, and repeatable tests.
Quick start
Build the complete solution with .NET 8.
Core libraries are cross-platform where the transport permits it. WPF applications and the current raw-Ethernet transport require Windows.

Transparent capability boundaries.
ARIEC61850 is intended for isolated laboratories, approved commissioning work, education, and protocol research. It does not claim formal third-party IEC 61850 conformance. Active control and process-bus publishing require an approved test plan, authority, isolation boundary, and independent verification.
Terminology: “native C#/.NET” means a project-owned managed implementation rather than an application wrapper. “Smart Control” means automated protocol discovery and sequence selection; it does not mean autonomous decision-making or permission to operate equipment.
