the contemporary industrial landscape is characterized by increasing complexity, requiring high-speed data acquisition, real-time processing, and robust human-machine interaction. At the core of this infrastructure lies the integration of Programmable Logic Controllers (PLCs) and Supervisory Control and Data Acquisition (SCADA) systems. This article explores the optimization of the interface between these two layers, focusing on data transmission protocols, latency reduction, and cybersecurity within the framework of Industry 4.0. By analyzing the shift from proprietary protocols to open standards like OPC UA and MQTT, the study demonstrates how optimized integration enhances decision-making and reduces downtime in complex technological processes such as petrochemical refining and automated manufacturing.
