Analysis of the operation of a TSN switch and other devices using executable QR codes

TL;DR

This paper demonstrates how executable QR codes can be used in industrial networks to assess TSN switch operation by analyzing status LEDs without internet, detailing generation and execution processes.

Contribution

It introduces the use of executable QR codes for industrial network device monitoring, providing a detailed methodology for their creation and use in offline environments.

Findings

Executable QR codes can effectively monitor TSN switch status.

The process enables offline assessment of industrial network devices.

A detailed chain of generation and execution of sQRy is provided.

Abstract

Executable QR codes, also known as sQRy, are a technology aimed at inserting executable programs in a QR code. Through a concrete example, in this paper, we demonstrate their usage in the context of industrial networks in order to assess the operation of a TSN switch by analyzing its status LEDs even in the absence of an internet connection. The entire generation chain that is used to create the sQRy, as well as the corresponding execution chain that, starting from the sQRy, runs it on a mobile device, has been detailed through examples.
