Abstract
Programmable logic controllers, or PLCs for short, is ubiquitous in the field of industrial automation. These devices are used to control and monitor a variety of processes related to production, ensuring that everything runs smoothly and efficiently. Unfortunately, there are currently no reliable means of verifying the accuracy and reliability of these devices, which can lead to serious consequences in the event of an error or malfunction. To address this issue, researchers are exploring the use of advanced technologies such as blockchain to provide greater transparency and security PLC operations.
