In essence, this Technical Note (TN) is very similar to [[MISC-TN-024: Automated test equipment (ATE) monitoring with SBCSPG gateway and ThingsBoard IoT platform|this one''MISC-TN-024: Automated test equipment (ATE) monitoring with SBCSPG gateway and ThingsBoard IoT platform'']]. There is a noticeable difference, however, as a different software stack was used on the edge device. In this case, [https://www.lfedge.org/projects/fledge/ LF EdgeFledge] was utilized.

As described in [[MISC-TN-024: Automated test equipment (ATE) monitoring with SBCSPG gateway and ThingsBoard IoT platform|''MISC-TN-024'']], the PLC we want to talk to is connected to a different subnet, namely 192.168.30.0/24. For testing the connection to the PLC, after adding the required subnet configuration, the <code>modbus</code> command line tool was used, which is provided by the <code>modbus_cli</code> package. In the following example, the register mapped ad the address 300 is read.

In order to upload collected data to ThingsBoard platform, a simple North plugin was developed. To this end, the Microsoft Azure plugin was used as reference. The ThingsBoard South North plugin is minimalist and '''unfit for a real-world production environment'''. Nevertheless, it was enough to perform the basic tests described in this TNdocument. Before testing this new plugin, the <code>mosquitto-clients </code> package was installed as the plugin invokes the <code>mosquitto_pub</code> command line tool.

ThingsBoard IoT allows Similarly to create easily custom dashboards to visualize data. At what we did in [[http://ec2-15-160-47-190.euMISC-southTN-1.compute.amazonaws.com024:8080/dashboard/1178fb20Automated test equipment (ATE) monitoring with SBCSPG gateway and ThingsBoard IoT platform|''MISC-e56dTN-11ec-8592-e3cb29424137?publicId=28967df0-e56d-11ec-8592-e3cb29424137 this link024'']] such , we created a simple dashboard is available showing some temperatures and currents of to visualize in real-time on cloud side collected data as shown in the arm's jointsfollowing example.[[File:ATE monitoring SBCSPG ThingsBoard dashboard1-Fledge-8.png|center|thumb|600x600px|Visualization of uploaded data.]]
