What Is The Main Difference Between Dtm And Dd Configuration Methods?

1.	What Is The Main Difference Between Dtm And Dd Configuration Methods?
Answer» The FDT standard supports both DD and DTM CONFIGURATION methods. The DD (Device Description) Language allows a device to be described using a TEXT like language. This is then compiled into a DD file that is UNIQUE for each HART, FF, and PROFIBUS network. The host system interprets the compiled DD file and DETERMINES how a device appears in the applications.. While the DD method is a simple way to describe the device, it is at the same time limited in the features it offers. The DTM method of representing a device is consistent in any FDT Frame application. The device supplier is in control of the visualization, functionality and advanced features.
