You can think about this This Technical Note (TN) as an evolution of the article "[[MISC-TN-021: SBCSPG and ThingsBoard IoT]]". The use case described here is a real-world application based on the same elements:

The implementation is suitable for a production environment. Unlike what we did for [[MISC-TN-021: SBCSPG and ThingsBoard IoT|this TN]], in this case the ThingsBoard IoT platform was installed on the cloud, specifically on an AWS EC2 instance running Ubuntu Linux. The following diagram shows the complete solution.

Technically, the gateway can communicate with the ATE using different physical links and protocols. In the example under discussion, the physical link is Ethernet and the protocol is Modbus/TCP. The gateway retrieves periodically some data regarding the robotic arm used to move the device under test (DUT). These data are [https://www.universal-robots.com/articles/ur/interface-communication/modbus-server/ exposed by the PLC governing the arm] and are documented in detail [https://s3-eu-west-1.amazonaws.com/ur-support-site/16377/ModBus%20server%20data.pdf here].

To run this esample, the most important module to configure was the [https://thingsboard.io/docs/iot-gateway/config/modbus/ Modbus connector]. The following box shows the resulting configuration file needed to poll some variables of the arm's joints (namely temperatures and currents).<syntaxhighlight lang="json">

ThingsBoard IoT allows to create easily custom dashboards to visualize data. At [http://ec2-15-160-117-174.eu-south-1.compute.amazonaws.com:8080/dashboard/1178fb20-e56d-11ec-8592-e3cb29424137?publicId=28967df0-e56d-11ec-8592-e3cb29424137 this link] such a dashboard is available showing some temperatures and currents of the arm's joints.
