| − | 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:
| |
| − | * [[MISC-TN-004: Running Debian (armbian) on SBCSPG#The hardware platform|The ''SBCSPG'' industrial gateway]]
| |
| − | * [https://thingsboard.io/docs/ ''ThingsBoard IoT platform'']
| |
| − | * [https://thingsboard.io/docs/iot-gateway/what-is-iot-gateway/ ''ThingsBoard IoT gateway''].
| |
| − | The application is to monitor robotized DAVE Embedded Systems' ATEs like the one shown [https://youtu.be/OoNiKgJXq00?t=409 here].
| |
| − | | |
| − | == Implementation ==
| |
| − | 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.

| − | [[File:ATE monitoring SBCSPG ThingsBoard.png|center|thumb|1000x1000px]] | |
| − | | |
| − | 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].

| − | === ThingsBoard IoT configuration ===
| |
| − | To install ThingsBoard IoT platform on an EC2 instance, [https://thingsboard.io/docs/user-guide/install/cluster/aws-self-hosted-setup/ these instructions] were followed.
| |
| − | | |
| − | === ThingsBoard IoT gateway configuration ===
| |
| − | 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">

| − | == Dashboards ==
| |
| − | ThingsBoard IoT allows to create easily custom dashboards to visualize data. At [http://ec2-15-160-47-190.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.
