IEC 62453-1:2025 PDF

Overview

IEC 62453-1:2025 is the foundational document in the IEC 62453 series, setting out the overview and guidance for the Field Device Tool (FDT) interface specification. Published by the International Electrotechnical Commission (IEC), this standard provides a structured approach to integrating devices, fieldbuses, and control systems within industrial automation environments. The third edition introduces key technical revisions, most notably the incorporation of a new implementation technology and an OPC UA information model for FDT, enhancing compatibility and interoperability.

This standard is essential for developers, system integrators, and manufacturers seeking consistent and open interfaces for process and factory automation. The guidance within IEC 62453-1 is applicable across various stages of the automation life cycle, supporting a wide array of industrial applications.
