CLI Verification

Endpoint from deployed config:

• opc.tcp://localhost:4840/LmxOpcUa

CLI used:

• C:\Users\dohertj2\Desktop\lmxopcua\tools\opcuacli-dotnet\bin\Debug\net10.0\opcuacli-dotnet.exe

Commands run:

opcuacli-dotnet.exe connect -u opc.tcp://localhost:4840/LmxOpcUa
opcuacli-dotnet.exe read -u opc.tcp://localhost:4840/LmxOpcUa -n 'ns=1;s=MESReceiver_001.MoveInPartNumbers'
opcuacli-dotnet.exe read -u opc.tcp://localhost:4840/LmxOpcUa -n 'ns=1;s=MESReceiver_001.MoveInPartNumbers[]'

Observed results:

• connect: succeeded, server reported as LmxOpcUa.
• read ns=1;s=MESReceiver_001.MoveInPartNumbers: succeeded with good status 0x00000000.
• read ns=1;s=MESReceiver_001.MoveInPartNumbers[]: failed with BadNodeIdUnknown (0x80340000).

Instance 2 (Redundant Secondary)

Deployed: 2026-03-28

Deployment path: C:\publish\lmxopcua\instance2

Configuration:

• OpcUa.Port: 4841
• OpcUa.ServerName: LmxOpcUa2
• OpcUa.ApplicationUri: urn:localhost:LmxOpcUa:instance2
• Dashboard.Port: 8082
• MxAccess.ClientName: LmxOpcUa2
• Redundancy.Enabled: true
• Redundancy.Mode: Warm
• Redundancy.Role: Secondary
• Redundancy.ServerUris: ["urn:localhost:LmxOpcUa:instance1", "urn:localhost:LmxOpcUa:instance2"]

Windows service:

• Name: LmxOpcUa2
• Display name: LMX OPC UA Server (Instance 2)
• Account: LocalSystem
• Endpoint: opc.tcp://localhost:4841/LmxOpcUa

Instance 1 redundancy update (same date):

• OpcUa.ApplicationUri: urn:localhost:LmxOpcUa:instance1
• Redundancy.Enabled: true
• Redundancy.Mode: Warm
• Redundancy.Role: Primary
• Redundancy.ServerUris: ["urn:localhost:LmxOpcUa:instance1", "urn:localhost:LmxOpcUa:instance2"]

CLI verification:

opcuacli-dotnet.exe redundancy -u opc.tcp://localhost:4840/LmxOpcUa
  → Redundancy Mode: Warm, Service Level: 200, Application URI: urn:localhost:LmxOpcUa:instance1

opcuacli-dotnet.exe redundancy -u opc.tcp://localhost:4841/LmxOpcUa
  → Redundancy Mode: Warm, Service Level: 150, Application URI: urn:localhost:LmxOpcUa:instance2

Both instances report the same ServerUriArray and expose the same Galaxy namespace (urn:ZB:LmxOpcUa).

Notes

The service deployment and restart succeeded. The live CLI checks confirm the endpoint is reachable and that the array node identifier has changed to the bracketless form. The array value on the live service still prints as blank even though the status is good, so if this environment should have populated MoveInPartNumbers, the runtime data path still needs follow-up investigation.
