The concept of Industry 4.0 is based on continuous monitoring of production processes and decision-making driven by real-time data. Without reliable information, it is impossible to implement predictive maintenance, energy optimization, automated planning, or meaningful OEE analysis. If data is delayed, incomplete, or inconsistent, digitalization becomes only superficial. IT systems may be in place, but they do not deliver real business value. That is why it is critical to build an architecture in which data is collected automatically, consistently, and centrally.
