A set of nodes to connect between the data from different sources and OCTOBUS cloud Alt text

Installing OCTOBUS connector using npm

# change to your ~./node-red/ folder
cd ~/.node-red/
npm install npm i @octobus/node-red-contrib-octobus-connector

Installing OCTOBUS connector via Node-RED palette

You can install the node also via the Manage palette feature in the Node-RED administration UI.

Connecting to OCTOBUS via OPC UA using Generated Flow function on OCTOBUS

1: Create Client on OCTOBUS

Go to Clients Tab create new Client.
On Client Type select Node-RED.

2: Create Data Flow on Client

The data flow on OCTOBUS doesn't the same definition on Node-RED. If you have multiple data flow on client it will be created on the same flow on Node-RED.

Names data flow and select protocol to OPC UA.
Go to Setting/Parameters - Fill the setting and parameters for OPC UA.
Go to Measurement Mapping tab - Add and select asset. - Select measurement that you want to map varaible/tag inside of OPC Server to OCTOBUS. - Fill the NodeId from OPC server then select Sampling Method. ( Subscribe interval will be fixed to 300 ms) - Select more assets or measurements if it's needed then click create.

3: Deploy to Node-RED

Generate Flow for Node-RED.
Copy or Download the configuration.
Open Node-RED web application.
Click the hamburger button and then select import.

Paste the configuration or select the downloaded configuration file then click import.
You will see the pop up that show the flow has been imported then DEPLOY it!

Connecting to OCTOBUS using MQTT Client and OCTOBUS payload node.

1: Create Client on OCTOBUS

Go to Clients Tab create new Client.
On Client Type select Generic MQTT.
Select any assets which you want to add to the client.

2: Preparing nodes on Node-RED

Prepare the OCTOBUS payload node - For each OCTOBUS payload reserve for each measurement in OCTOBUS - On OCTOBUS you will see the message payload format for each measurement. - Copy Asset Id and Measurement Id from OCTOBUS and paste to OCTOBUS payload on Node-RED. - Select the Data type which have to match on OCTOBUS.
Prepare the MQTT Client node - On mqtt out node, fill the topic and set the QoS to 1. - Fill the MQTT Endpoints, username and password on Connection and Security tab accordingly
The wire for OCTOBUS payload node and mqtt out node will be look like this.
