REMOTE OPERATIONS WEB INTERFACE USING NODE RED BACKEND.

is a flow-based development tool for visual programming, developed originally by IBM for wiring

together hardware devices, APIs and online services as part of the Internet of Things initiative. Node-RED
provides a web browser-based flow editor, which can be used to interlink Node-JS/JavaScript functions and
create a full application in hours. The VS-4 Wi-Fi Bridge provides the APIs needed to interface with Node-Red
out of the box (Websockets and webserver).

Node-red backend runs on a computer on same network as the Wi-Fi bridge. This computer serves custom
designed web pages called Dashboards, to clients devices like other PCs or cell phones, on same network.

To design these Dashboards or Flows, Node red’s br

owser-based front end provides an extensive library of

graphical elements representing logical functions of various complexities, and the programmer just have to
interconnect them to implement the desired behavior.

On the example below, a simple Oven management interface allows operators to start an oven remotely either
in fix temperature mode or Program mode. For fixed temperature, a slider control is provided to set the
temperature along with a start button. If Program mode is selected, the operator can chose which program
and Pattern to use before clicking Start button. After the over is in the RUN mode, a Status dashboard is
displayed.

Vortex consulting can create custom Node-Red Dashboards and applications through consulting services.
