includes the engineering and commissioning of field devices. Functionality for documentation and audit trail support is also considered. Examples and use cases are mainly given for actors, sensors and remote I/Os. Of course, FDT is prepared to be used for devices like drives, analyzers, recorders, etc. as well. The FDT interfaces are designed in such a way as to support all significant fieldbus protocols. The main focus of this version of FDT does not lie on any specific fieldbus protocol. Due to the scalable structure of FDT it will be easy to add new schemas in order to extend the scope to new protocols.
