Modelling IoT flows with nodes
To combine physics and logic, Node-RED models ("
flows
") and works with
("
nodes
") which represent objects in the Internet of Things. You can relate
these objects to physical interfaces as well as to logic functions.
Figure 54: Comparison of the physical and logic view
By means of Drag&Drop the nodes are interactively wired with one another
to get flows, as shown in the following figure.
Figure 55: Wiring the nodes
The following basic properties apply to one Node-RED node:
·
A node fulfills a specific, defined task.
·
A node has entry masks for setting the parameters.
·
A node can have inputs and outputs.
·
A node can be connected with other nodes via its inputs and outputs.
·
A node can modify and overwrite data before passing the data on.
·
A node transports data via the msg object in the JSON format.
