LmxProxy is no longer needed. Moved the entire lmxproxy/ workspace, DCL
adapter files, and related docs to deprecated/. Removed LmxProxy registration
from DataConnectionFactory, project reference from DCL, protocol option from
UI, and cleaned up all requirement docs.
Composable StaleTagMonitor class in Commons fires a Stale event when no
value is received within a configurable max silence period. Integrated
into both LmxProxyDataConnection and OpcUaDataConnection adapters via
optional HeartbeatTagPath/HeartbeatMaxSilence connection config keys.
When stale, the adapter fires Disconnected triggering the standard
reconnect cycle. 10 unit tests cover timer behavior.
The LmxProxy client's ExtractArrayValue now returns proper .NET arrays
(bool[], int[], DateTime[], etc.) instead of ArrayValue objects. Removed
the reflection-based FormatArrayContainer logic — IEnumerable handling
is sufficient for all array types.
ArrayValue from LmxProxy client was showing as type name in debug views.
Added ValueFormatter utility and NormalizeValue in LmxProxyDataConnection
to convert arrays at the adapter boundary. DateTime arrays remain as
"System.DateTime[]" due to server-side v1 string serialization.
Switches from v1 string-based proto stubs to the production LmxProxyClient
(v2 native TypedValue protocol) via project reference. Deletes 6k+ lines of
generated proto code. Preserves ILmxProxyClient adapter interface for testability.
- Add JoeAppEngine folder to OPC UA nodes.json (BTCS, AlarmCntsBySeverity, Scheduler/ScanTime)
- Fix DataConnectionActor: capture Self in PreStart for use from non-actor threads,
preventing Self.Tell failure in Disconnected event handler
- Implement InstanceActor.HandleConnectionQualityChanged to mark attributes Bad on disconnect
- Fix LmxFakeProxy TagMapper to serialize arrays as JSON instead of "System.Int32[]"
- Allow DataType and DataSourceReference updates in TemplateService.UpdateAttributeAsync
- Update test_infra_opcua.md with JoeAppEngine documentation
Replace stub ILmxProxyClient with production proto-generated gRPC client
(RealLmxProxyClient) that connects to LmxProxy servers with x-api-key
metadata header authentication. Includes pre-generated proto stubs for
ARM64 Docker compatibility, updated adapter with proper quality mapping
(Good/Uncertain/Bad), subscription via server-streaming RPC, and 20 unit
tests covering all operations. Updated Component-DataConnectionLayer.md
to reflect the actual implementation.
- DataConnectionActor now stores and passes connection details to adapter ConnectAsync
- DataConnectionManagerActor passes connection details when creating actor
- RealOpcUaClient uses DiscoveryClient for endpoint selection with no-security preference
- Added certificate trust store paths to prevent TrustedIssuerCertificates error
- Sanitize connection names for Akka actor paths (replace spaces)
- Add connection binding UI to Instances page (per-attribute and bulk assign)
- FlatteningService populates Connections dict from bound data connections
- Real OPC UA client using OPC Foundation SDK for live tag subscriptions
- DataConnectionFactory uses RealOpcUaClientFactory by default
- OpcUaDataConnection supports both "endpoint" and "EndpointUrl" config keys
