v1.6.1

Date: 2026-11-12
Previous release: v1.6.0

Fixed

• iec61850-interop-libiec61850 resolves --remote once at start-up and gives libiec61850's RSession the IPv4 address. libiec61850's UdpSocket_sendTo runs getaddrinfo on the address for every SPDU, so with a container name the R-SV publisher made one DNS query per sample. On the arm64 runner that held it at 12,163 and 13,054 of the expected 16,000 samples in 4 s, against an 80 % floor (sv.msvcb01.udp, libiec61850 → dscsystems). The subscriber received every sample; only the publisher's rate was short. The contract and the checks are unchanged.

Changed

• scripts/lib.sh run_client_pair: a client that writes nothing has its exit code, its stderr and the server's last log lines written to the log. A client run that Docker itself cannot start (exit 125) is retried like a failed association. A main CI run of this release's fix failed once with libiec61850-ied-reporter -> iec61850-rust-ied-server: no JSON Lines output, 0.7 s after the previous check finished, with stderr discarded; it did not reproduce in 40 local runs. The next occurrence shows its cause.

v1.6.0

Date: 2026-11-12
Previous release: v1.5.0

Added

• iec61850-interop-libiec61850 implements contract 1.4 --transport udp (R-GOOSE and R-SV) with libiec61850's own RSession: the image builds the pinned libiec61850 with Mbed TLS v3.6.0 (2ca6c28, Apache-2.0 OR GPL-2.0-or-later) in third_party/mbedtls, which compiles R-GOOSE, R-SV and the HMAC. --capabilities carries "transports":["ethernet","udp"]; udpTransport.libiec61850 is true. The transport is adapters/libiec61850/src/rudp.c; docs/routable.md lists what libiec61850 does and does not do.
• scripts/interop.sh runs the udp checks between libiec61850 and dscsystems in both directions (GOOSE and SV pass). libiec61850 → libiec61850 is a known failure, asserted: its RSession writes each APDU length two octets too long and refuses its own SPDUs as malformed (waiver libiec61850-rsession-apdu-length).
• fixtures/capabilities.json: five known limitations of libiec61850's RSession (APDU length, no version 1 sender, no HMAC-SHA256-80, the HMAC-SHA256-256 length octet, no replay window).

Changed

• The libiec61850 image links Mbed TLS, which also makes TLS available to its MMS code; no adapter configures it. versions.yaml records the Mbed TLS pin under libiec61850.

v1.5.0

Date: 2026-11-11
Previous release: v1.4.0

Added

• Contract 1.4 (minor): --transport udp on the GOOSE and SV publishers and subscribers, R-GOOSE and R-SV: the APDUs in the session protocol of IEC TR 61850-90-5 over UDP, signed with HMAC-SHA256-80, -128 or -256 under the key of --key-id and --key (--mac, --session-version 1|2). Publishers send to --remote; subscribers receive on --listen (:102) or a multicast --group, refuse unsecured SPDUs unless --allow-unsecured, and report each refused SPDU as a new reject event with a reason (unknown-key, authentication, unsecured, replay, malformed). A goose event received over UDP carries from, the sender's address. --capabilities of an image that has it carries "transports":["ethernet","udp"]. Default --transport ethernet: nothing changes for a harness that does not ask for it. docs/routable.md.
• iec61850-interop-dscsystems implements it with dscsystems/go-iec61850's rsession (v0.6.6, already pinned): adapters/dscsystems/internal/rudp, unit-tested on the loopback. The other images do not (fixtures/capabilities.json udpTransport, a new column in the capability matrix).
• scripts/goose-crosscheck.sh and scripts/sv-crosscheck.sh with TRANSPORT=udp: signed SPDUs to the subscriber's container, after a rogue publisher with the same key ID and other key material whose SPDUs must all be refused. scripts/interop.sh runs both between every pair of adapters with the udp transport (today dscsystems with itself; independent pairs come with a second stack).

v1.4.0

Date: 2026-11-06
Previous release: v1.3.0

Added

• Adapter cbsigma, image ghcr.io/otfabric/iec61850-interop-cbsigma: a fifth independent reference, in Go, on cB-Sigma/iec61850 v0.1.0 (MMS client, the IEC 61850 client services, GOOSE) and cB-Sigma/iec61850-sim v0.1.0 (the simulated IED), both Apache-2.0 and pinned by tag (cB-Sigma publishes no releases). Commands: cbsigma-ied-server (the fixture IED built by the simulator's own SCL loader from interop.icd: logical nodes, data sets, report control blocks and the three controls with their ctlModel, then values.json), cbsigma-ied-client, cbsigma-ied-controller (direct, SBO and SBOw through the library's Operate, which runs the whole sequence of the control model), cbsigma-ied-reporter, cbsigma-goose-publisher and cbsigma-goose-subscriber (frames encoded and decoded by the library). No MMS or SV commands: the simulator is an IED, not a generic MMS server, and SV is out of this adapter's scope; they answer unsupported. The ICCP / TASE.2 simulator is not used.

• adapters/cbsigma/go.mod holds the pins (and golang.org/x/net raised to v0.62.0 past the advisories of v0.58.0); the Dockerfile fails when its IEC61850_VERSION/IEC61850_SIM_VERSION differ from go.mod, and scripts/check-versions.py when versions.yaml, the Dockerfile, go.mod and the NOTICE disagree. The image carries the licence and notice of every linked module under /licenses.

• CI builds and smoke-tests the image, runs its MMS and IED commands against libiec61850 in both directions and GOOSE between it and every other publisher and subscriber, and vets, lints, tests (-race) and govulnchecks the adapter. The Release workflow builds and publishes it for linux/amd64 and linux/arm64; manifest.json gains cbsigma (iec61850, iec61850-sim, independent: true) and its image digest. The Upstream workflow compares both tags with the latest ones (scripts/latest-upstream.py cbsigma, scripts/build-candidate.sh cbsigma "iec61850@<tag> iec61850-sim@<tag>").

• fixtures/capabilities.json: the cbsigma commands and upstreams, four known limitations found with it (below), iec61850-rust's report control blocks' DatSet without the logical device (LLN0$dsInterop), which dscsystems' new interop suite against this harness found, and its refusal of GetBRCBValues as one Read of the whole BRCB.

• The cbsigma adapter module declares go 1.26.10, as the dscsystems one, so CI vets and scans it with a standard library that has the fixes govulncheck asks for.

• Contract 1.3 (minor): *-ied-reporter --trigger dchg|gi. With gi the reporter writes the URCB's GI (operation trigger-gi) instead of GGIO1.SPS1.stVal[ST] and gets the general interrogation report of both members of dsInterop, from every server, including those that refuse ST writes as IEC 61850-7-2 says. --capabilities of an image whose reporter takes it carries "reporterTriggers":["dchg","gi"]; all five reference images do.

• Report and control evidence: scripts/smoke.sh and scripts/interop.sh check the GI report of every reporter that takes --trigger gi (both members included, reasons gi, values [false, 1]) and that a controller's operate succeeds and stVal follows. Before, a reporter's or controller's output was only checked to be JSON, so a pair passed without a report or a control. Pairs that fail for a registered limitation have to fail that way (waivers iec61850-rust-urcb-implicit-reservation, iec61850bean-report-data-references) and fail the run once they pass.

Fixed

• The reporters and controllers of libiec61850, iec61850bean, dscsystems and iec61850-rust addressed InteropLD/LLN0.RP.urcb01 and InteropLD/GGIO1.<DO> as given: they found the URCB and the controls only on a server that names its logical device by the bare instance (OT Fabric's own image), and failed with object-does-not-exist against every reference server, which names it InteropIEDInteropLD and the URCB instance urcb0101. They now take the logical device from the server directory and the URCB or its first instance from the logical node directory, as the IED clients already did (contract 1.3). The line targets carry the logical device found.
• iec61850-rust's reporter named a member included for several reasons "unknown"; it now gives the first in the contract's order.
• libiec61850-ied-controller and iec61850-rust-ied-controller read --ctlval with atoi, so the contract's --ctlval true operated false; it takes true|false|1|0 (anything else is an argument error, exit 1).

Changed

• dscsystems/go-iec61850 moves from commit 6bf3f37 (v0.6.5-1) to its release v0.6.6 (4833767). It types Enum attributes as an 8-bit Integer, so the iec61850bean client now reads LLN0.Mod.ctlModel[CF] from the dscsystems IED server, and that known limitation is removed. It also refuses a control write to an object without a control structure, and names logical devices by ldName on request (not used here). The Dockerfile pins the version as DSCSYSTEMS_VERSION (the tag, or the pseudo-version of an untagged commit) next to DSCSYSTEMS_SHA, and checks that the module proxy resolves one to the other; scripts/build-candidate.sh dscsystems sets both.
• The Own stack (go-iec61850) workflow takes the reference adapters from make print-published-adapters of the harness release it tests against, so OT Fabric's own image is tested against cbsigma once this release is the latest.

Known limitations

• cbsigma-ied-server refuses writes of ST and MX (object-access-denied), as IEC 61850-7-2 makes them read-only, so a reporter cannot make the data change it waits for; reports from the simulator's own changes are tested in the adapter's unit tests.
• The simulator describes Enum attributes as Integer(32), so the iec61850bean client cannot map LLN0.Mod.ctlModel[CF].
• iec61850bean's server reads a data set only with specificationWithResult TRUE, which cB-Sigma's client leaves at its default (FALSE).
• iec61850-rust accepts only an 11-bit parameterCBB in MMS Initiate; cB-Sigma sends the 18 bits of ISO 9506:2003, so the two cannot associate in either direction.
• Found by the new report checks: iec61850-rust's server enables a URCB only after the client wrote Resv (no implicit reservation; registered since v1.0 for the libiec61850 client, now seen with every client but dscsystems'), and iec61850bean's server announces data references in OptFlds without sending them.

v1.3.0

Date: 2026-11-06
Previous release: v1.2.0

Added

• own/go-iec61850/: OT Fabric's own stack (go-iec61850 and the go-mms it is built on) behind the same contract, as adapter otfabric with the commands otfabric-mms-server, otfabric-mms-client, otfabric-ied-*, otfabric-goose-* and otfabric-sv-*. The manual workflow Own stack (go-iec61850) builds it from the latest go-iec61850 and go-mms releases, tests it against the reference images of the latest harness release and publishes ghcr.io/otfabric/iec61850-interop-otfabric:<go-iec61850 version> and :latest. It is not an independent implementation, and it is not in this release or its manifest.json (ADR-0012); results against it are at most "Tested".
• Contract 1.2 (minor): --version and --capabilities may carry upstream (name, version, revision, license, independentEngine). The reference images do not, and are recorded as independent; results.json takes independent from what an image says of itself.
• scripts/smoke.sh <adapter> (the contract smoke test of one image, driven by its --capabilities) and scripts/interop.sh <adapters…> (MMS and IED clients and servers of every adapter against the first in both directions, GOOSE and Sampled Values between every publisher and subscriber), make smoke, make interop, make lint, make print-adapters, ADAPTERS. Any image can stand in for an adapter with ADAPTER_IMAGE_<adapter>.

Changed

• The layout follows the other harnesses: docs/contract.md is docs/CONTAINER_CONTRACT.md, COVERAGE.md is docs/CAPABILITIES.md, docker-compose.yml is compose.yaml; scripts/smoke-test.sh is split into scripts/lib.sh, scripts/smoke.sh and scripts/interop.sh. Each stack's clients now also run against its own server, and the hub's reporter and controller against every other stack's server. The root go.mod (no packages) is gone. The image names, commands and contract are unchanged.
• CI runs shellcheck and the REQUIREMENTS.md R1 check (no reference to a library under test outside own/).

v1.2.0

Date: 2026-11-04
Previous release: v1.1.1

Added

• *-ied-client --local-tsel HEX --remote-tsel HEX: the calling and called COTP T-selectors (1 to 4 octets in hex) for libiec61850, iec61850bean and iec61850-rust. Without them each stack sends its own defaults, now documented in docs/contract.md (libiec61850 and iec61850-rust 0001/0001, iec61850bean 0000/0001). Consumers use this to run independent clients with the selectors IEDs and engineering tools use (01, 0001, 00000001) against a server that accepts any selector or requires one. Motivated by otfabric/go-iec61850#28, where an IED refused a client that sent none. Contract 1.1 (a minor addition: new flags, old behaviour by default).
• dscsystems: dscsystems/go-iec61850 cannot set the selectors, so its clients answer the flags with unsupported (exit 4), recorded as a known limitation.

v1.0.1

Date: 2026-10-28

Summary

Provenance fix. The release's manifest.json reported the adapter's own
Maven version (1.0.0) in its iec61850bean field; it now reports the
iec61850bean library version the image is built with (1.9.0). Images,
commands, events and fixtures are unchanged from v1.0.0.

Changes

Fixed

• manifest.json iec61850bean is read from the com.beanit:iec61850bean dependency of adapters/iec61850bean/pom.xml, not from the first <version> in the file.
• make ci prints the same version in its provenance block (it printed the POM modelVersion, 4.0.0).

v1.0.0

Date: 2026-10-28

Summary

The repository is renamed from mms-interop to iec61850-interop, since it
covers MMS, IEC 61850 IED services, GOOSE and Sampled Values, and the
adapter contract becomes stable. The adapters, commands, fixtures and event
shapes are those of v0.4.1; what changes is where they are published and the
promise that comes with them.

Breaking changes

• Images move to new names. Pull ghcr.io/otfabric/iec61850-interop-<stack>
  instead of ghcr.io/otfabric/mms-interop-<stack>:
  • ghcr.io/otfabric/iec61850-interop-libiec61850
  • ghcr.io/otfabric/iec61850-interop-iec61850bean
  • ghcr.io/otfabric/iec61850-interop-dscsystems (GPL-3.0)
  • ghcr.io/otfabric/iec61850-interop-iec61850-rust
• Local builds are tagged iec61850-interop-<stack>:local; the Compose
  project and the GOOSE/SV bridge network are iec61850-interop and
  iec61850-interop-goose.
• The Go module paths are github.com/otfabric/iec61850-interop and
  github.com/otfabric/iec61850-interop/adapters/dscsystems; the Rust crate is
  iec61850-interop-iec61850-rust.
• A fixture without identity.model now identifies as iec61850-interop
  (was mms-interop). fixtures/mms/interop.json sets the model, so the
  published images answer as before.

Unchanged, so consumers only swap the image references: the command names
(libiec61850-ied-server, ...), their flags and output, the consumer
environment variables (LIBIEC61850_IMAGE, IEC61850BEAN_IMAGE,
DSCSYSTEMS_IMAGE, IEC61850RUST_IMAGE), and the fixture revisions
mms-v2, iec61850-v3, goose-v1, sv-v1.

Compatibility promise

From v1.0.0 the repository follows semantic versioning. The image names,
command names and flags, event and operation shapes, exit codes, fixture
revisions, and the schemas of capabilities.json and manifest.json change
incompatibly only in a new major version. Minor versions add (commands,
optional fields, event types, fixture revisions next to the old ones); patch
versions fix adapters to match the contract and update known limitations.
Consumers ignore fields and events they do not know. The full statement is
in docs/contract.md.

Changes

Added

• docs/contract.md: the shared adapter contract (ready, version and
  capabilities events, fixed-sequence client output, exit codes) and the
  stability promise; docs/goose.md and docs/sv.md refer to it.
• A stack × capability matrix in README.md and COVERAGE.md, generated
  from fixtures/capabilities.json by scripts/gen-coverage.sh;
  --check mode runs in CI and in make validate-fixtures.
• manifest.json gains repository and svFixture.
• org.opencontainers.image.source and description labels on the
  libiec61850 and iec61850bean images (the other two had them), pointing at
  https://github.com/otfabric/iec61850-interop.

Changed

• README rewritten around the four stacks and four profiles: capability
  matrix, image names and digest pinning, quick starts for MMS, IED, GOOSE
  and SV, L2 networking on Linux and macOS, licensing per image, consumer
  repositories.
• capabilities.json adapterVersion is 1.0.0.
