IoTGateway/Node-Red for GW EIS

Introduction

Node-RED is a visual wiring tool for the Internet of Things and is provided by IBM Emerging Technologies. Node-Red has several features, including browser-based flow editing, built on Node.js and social development. Because of browser-based, the user can use it more easily. Node-Red is based on Node.js, so user can use its nodes by using JavaScript. Node-Red also have many active communities. If the user finds bugs, he can find a solution and fix it easily. The user can use JSON format string to import or export the created flow easily.
A lot of useful nodes are provided by Advantech NodeRed Server IoTGateway installer, including node-red-contrib-flow-dispatcher, node-red-contrib-susi and node-red-contrib-virtual-app-node. In this section, we are gonna introduce another two node groups, ui-flow-creator and WISE-Cloud. ui-flow-creator provides nodes to quickly, easily and automatically generate flows to represent dashboard for Advantech platforms supported by SUSIIoT. WISE-Cloud nodes make communications between NodeRED nodes and RMM agent can be easily achieved.

Node-Red Plug-ins Catogries

Category	Description	Nodes
UI-Flow-Creator	Provid  functions to auto-generate a flow with node-red-dashboard nodes to represent a device dashboard. UI-Flow-Creator nodes depend on node-susi and node-susiiot packages to read data and control devices.	1.nr_ui_flow_creator 2.ui_ui_creator_ctrl
WISE-Cloud	WISE-Cloud provide nodes to communicate with RMM Agent. Sending data to agent, receiving messages from agent and response RMM RESTful requests.	1.WISE-Cloud-Sender 2.WISE-Cloud-Receiver 3.WISE-Cloud-Responder

NodeRed Plug-ins Description

Node Name	Description	Input	Output
nr_ui_flow_creator	Auto-generate flow with node-red-dashboard nodes to represent the device dashboard according to user selected groups. Require node-susi and node-susiiot packages.	Auto-generated an inject node after flow deployment.	Auto-generated outputs according to user selected groups after flow deployment.
nr_ui_creator_ctrl	Control devices according injected values . Require node-susi and node-susiiot packages.	SUSIIoT control information in 'topic' propery and control value in 'payload' property.	Control result returned by SUSIIoT.
WISE-Cloud-Sender	Send injected IPSO JSON string to RMM agent.	A string in 'payload' property which will be passed to RMM agent.	None
WISE-Cloud-Receiver	Receive messages from RMM agent with specified name and topics.	None	The received message (or RESTful request) from RMM agent is included in 'req' property.
WISE-Cloud-Responder	Response RESTful requests. The injected data must contain the source request information.	Source request is included in 'req' property and the corresponding response is in 'rep' property.	None
