Alarms (P_Alarms_PSM)

Under Def Stan 23-009 Arch-2 the alarms service is the sole publisher of C_Alarm and C_Alarm_Category_Definition. LRUs (including third-party apps that model an Alarm_Condition_Source) publish C_Alarm_Condition and, optionally, C_Alarm_Condition_Specification; the service falls back to alarm_specifications.json when the LRU does not supply a spec. Operator commands are published by the HMI (The_Authorised_Operator); the service replies on Alarms__CommandResponseType.

¹ gva-alarms publishes C_Alarm_Condition_Specification only as a fallback when the LRU has not published its own spec within 10 s of service start (see alarm_specifications.json → fallbacks[]).

² 3rd Party Apps: gva-app-bms, gva-app-shield-protocol, gva-app-defense-grid-run, gva-app-drone-invaders

Resource ID Allocation (P_Resource_ID_Allocation_PSM)

The registration handshake and platform-wide "configured-with-registry" health view. See the Registration Service page for the semantics.

¹ Via qt6-gva-resource-lib shared library (gva::GvaResource). ³ gva-registry also publishes an aggregate Registered_Platform_Resource stream by default for compatibility; disable with --disable-registry-aggregator for strict-compliance runs.

Platform Configuration (P_Platform_Configuration_PSM)

Platform-wide roles, resource specifications and operator commands. Registry publishes the state topics; HMI/operator drives the commands.

Usage & Condition Monitoring (P_Usage_And_Condition_Monitoring_PSM)

gva-uacm implements the SR-role Usage And Condition Monitoring Service (§2.5.4) plus a bridge role (§2.5.5–§2.5.7 / §7.2.1 / GVA_UCMR_003). It subscribes to the R-role specification/state surface, persists everything to PostGIS, derives Fault_Event samples from matching Fault_Code transitions, and answers O-role commands per GVA CRP v2.0 §3. See UACM Service.

³ Monitored_Resource_Specification and Fault_Event_Specification are the bridge-role dual channels: gva-uacm subscribes to them as the wire-authority input for WIRE_LEARNED promotion (§2.5.4–§2.5.7) and publishes surrogate samples at grace-elapse for entries that remain in the BRIDGE_FALLBACK role. Which side wins is decided per (resourceId, instanceId) key using the fallback authority precedence rule in the UACM Service docs.
