This standard BS EN IEC 62453-309:2022 Field device tool (FDT) interface specification is classified in these ICS categories:
35.110 Networking
35.100.05 Multilayer applications
25.040.40 Industrial process measurement and control
Communication Profile Family 9 (commonly known as HART®1) defines communication profiles based on IEC 61158-5-20 and IEC 61158-6-20. The basic profile CP 9/1 is defined in IEC 61784-1. This part of IEC 62453 provides information for integrating the HART® technology into the FDT standard (IEC 62453-2). This part of the IEC 62453 specifies communication and other services. This standard neither contains the FDT specification nor modifies it.
