Field device tool (FDT) interface specification - Part 2: Concepts and detailed description
IEC 62453-2:2022 explains the common principles of the field device tool concept. These principles can be used in various industrial applications such as engineering systems, configuration programs and monitoring and diagnostic applications. This document specifies the general objects, general object behavior and general object interactions that provide the base of FDT.
