This repository is a Go-based EdgeX Foundry Device Service which uses OPC-UA protocol to interact with the devices or IoT objects.
- Subscribe data from OPCUA endpoint
- Execute read command
- Execute write command
- MongoDB
- Edgex-go: core data, core command, core metadata
- OPCUA Server
Define devices for device-sdk to auto upload device profile and create device instance. Please modify configuration.toml file which under ./cmd/res folder

Policy = "None" # Security policy: None, Basic128Rsa15, Basic256, Basic256Sha256. Default: auto

KeyFile = "" # Path to private key.pem. Required for security mode/policy != None
NodeID = "ns=5;s=Counter1" # Node id to subscribe toA Device Profile can be thought of as a template of a type or classification of Device.
Write device profile for your own devices, difine deviceResources, deviceCommands and coreCommands. Please refer to cmd/res/OpcuaServer.yaml
Tips: name in deviceResources should consistent with OPCUA nodeid
