IEC62453-2:2016 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 standard specifies the general objects, general object behavior and general object interactions that provide the base of FDT.This second edition cancels and replaces the first edition published in 2009. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:- Clarification for categories of DTMs (e.g. new category ‘Composite Device DTM’)- Clarification: Command functions- New concept: Static function- Clarification for Communication Channel and communication- Clarifications for identification- Clarifications for scanning and DTM assignment- New concept: PLC tool support
