With the ongoing evolution of technology and the digitization of information, Ethernet-based network protocols have become increasingly prevalent. In scenarios involving explosive atmospheres, which were previously restricted to Fieldbus networks, Ethernet APL emerges as an alternative to bring digitization to process plants. In light of this growing trend, this work evaluates the replacement of the Profibus PA protocol with Ethernet APL, comparing their performances. The research focuses on the temperature control of an industrial furnace, a typical scenario in industrial plants. The results confirm that the implementation of Ethernet APL does not cause any losses in existing plants and offers additional qualitative advantages, as demonstrated in this work.
