Abstract:Diplomsko delo obravnava zasnovo in implementacijo sistema za oddaljeni nadzor programabilnih logičnih krmilnikov in drugih naprav, ki podpirajo protokol Modbus TCP. Sistem, namenjen preprostejšim, nekritičnim nalogam, predstavlja alternativo komercialnim rešitvam. Najprej opišemo protokola MQTT in Modbus TCP ter ostale tehnologije, ki smo jih uporabljali. Nato predstavimo, kako smo implementirali sistem, opišemo komponente, ki ga sestavljajo, in kaj je njihova naloga. Poseben poudarek namenimo varnosti. Za zaščito sporočil je implementiran hibridni model šifriranja, ki združuje asimetrično (RSA) in simetrično (AES) kriptografijo. Za upravljanje in pošiljanje ukazov skrbi spletni uporabniški vmesnik, razvit z ogrodjem Next.js. Sistem je zasnovan razširljivo in omogoča integracijo z drugimi orodji.

Title:Remote control of programmable logic controllers
Abstract:This graduate thesis addresses the design and implementation of a system for the remote monitoring and control of Programmable Logic Controllers (PLCs) and other devices supporting the Modbus protocol. The system, aimed at simpler, non-critical tasks, presents an alternative to commercial solutions. First, we describe the MQTT and Modbus TCP protocols and the other technologies used. We then present the system's implementation, outlining its components and their roles. A special emphasis is placed on security; a hybrid encryption model combining asymmetric (RSA) and symmetric (AES) cryptography is implemented to protect messages. Management and command execution are handled by a web user interface developed with the Next.js framework. The system is designed to be extensible and allows for integration with other tools.
Keywords:Programmable Logic Controllers, Modbus, MQTT, Next.js, Arduino
