A Node-RED node to communicate OPC UA.
Run command on Node-RED installation directory.
npm install
Install first node-opcua.
Use OpcUaItem to define variables. Use OpcUaClient to read / write / subscribe / browse OPC UA server. Added example flow for Browse (from file) TEST_OPCUA.json.
Subscription interval is not anymore used in read requests, but left in UI.
