OPC-UA Adapter

Adapter between Mainflux IoT system and an OPC-UA Server.

This adapter sits between Mainflux and an OPC-UA server and just forwards the messages from one system to another.

OPC-UA Server is used for connectivity layer and the data is pushed via this adapter service to Mainflux, where it is persisted and routed to other protocols via Mainflux multi-protocol message broker. Mainflux adds user accounts, application management and security in order to obtain the overall end-to-end OPC-UA solution.

Configuration

The service is configured using the environment variables presented in the following table. Note that any unset variables will be replaced with their default values.

Variable Description Default
MF_OPCUA_ADAPTER_HTTP_PORT Service HTTP port 8188
MF_OPCUA_ADAPTER_LOG_LEVEL Service Log level error
MF_NATS_URL NATS instance URL nats://localhost:4222
MF_OPCUA_ADAPTER_SERVER_URI OPC-UA Server subscription URI opc.tcp://opcua.rocks:4840
MF_OPCUA_ADAPTER_NODE_NAMESPACE OPC-UA Server Node Namespace 0
MF_OPCUA_ADAPTER_NODE_IDENTIFIER OPC-UA Server Node Identifier 2256
MF_OPCUA_ADAPTER_POLICY OPC-UA Server Policy
MF_OPCUA_ADAPTER_MODE OPC-UA Server Mode
MF_OPCUA_ADAPTER_CERT_FILE OPC-UA Server Certificate file
MF_OPCUA_ADAPTER_KEY_FILE OPC-UA Server Key file
MF_OPCUA_ADAPTER_ROUTE_MAP_URL Route-map database URL localhost:6379
MF_OPCUA_ADAPTER_ROUTE_MAP_PASS Route-map database password
MF_OPCUA_ADAPTER_ROUTE_MAP_DB Route-map instance name 0
MF_THINGS_ES_URL Things service event source URL localhost:6379
MF_THINGS_ES_PASS Things service event source password
MF_THINGS_ES_DB Things service event source DB 0
MF_OPCUA_ADAPTER_EVENT_CONSUMER Service event consumer name opcua
