Installation of the NCD Library Development Branch (temp-dev)

Installation via Node-RED

Requirements

  • Industrial IoT Gateway: An NCD Enterprise-series gateway.
  • Node-RED Access: Access to the Node-RED flow editor.
  • Network Connectivity: Active internet access for the gateway (required for library installation).

Procedure

Step 1. Go to ‘update ncd library‘ github repo and click on the copy raw file button:

Step 8. Enable the second flow by clicking the embedded left button, as shown in the following image:

This flow enables a command to restart Node-RED on the Gateway.

Step 9. Finally refresh the web browser page. It will take a few minutes to restart Node-RED.

After completing these steps, your NCD Library has been updated from the temp-dev branch.

Steps

Step 1: Using a PC with internet access that is also on the same network as the NCD Gateway (or connected via Ethernet), navigate to the NCD GitHub Library repository and switch to the temp-dev branch. Click the green ‘Code‘ button and select ‘Download ZIP‘ from the dropdown menu to save the library locally.

Step 2: Extract the contents of the ZIP file.

Step 4: Type cmd into the Windows Explorer Address Bar and press Enter to open a Command Prompt window within the current directory.

Step 5: Enter the following command to copy and replace the node-red-enterprise-sensors folder in the Gateway’s Node-RED directory. Replace xxxx with the last four digits of your Gateway’s MAC address (found on the nameplate located on the bottom of the unit):

				
					scp -r node-red-enterprise-sensors ncdio@ncd-xxxx.local:/home/ncdio/

Step 6: You will be prompted for the Gateway password. The default password is:

				
					ncdB3ast

Step 7: SSH to the Gateway:

				
					ssh ncdio@ncd-xxxx.local

Step 8: Use these commands to install the library:

				
					cd ~/.node-red
				
			
				
					npm install /home/ncdio/node-red-enterprise-sensors

Step 9: Once the process is complete, you may reboot Node-RED process, use this command:

				
					pm2 restart all
