FDT DTM Concept GSD file Technology GSD File Language General Section DP master Section DP slave Section Two types of configuration technology exist e Configuration technology based on FDT DTM technology e Configuration technology based on GSD files The FDT DTM concept specifies the interfaces between the engineering sys tems called Field Device Tools FDT and the device specific software com ponents called Device Type Managers DTM The FDT DTM concept separates the device dependent functionality which is in the DTM from the application It provides separate interfaces for device configuration monitoring and maintenance solutions which before largely depended on the manufacturer of the application Because of this concept FDT DTM technology is not limited to PROFIBUS applications In concept any type of network can be configured and accessed provided the appropri ate DTM s are available CX Profibus is an example of a FDT container application It is described in detail in the following sections The older and most commonly used configuration technology is the based on GSD files General Slave Data file A GSD file is a text file containing the characteristic features and configuration options of a device The device data base file of each device is loaded in the configurator and downloaded to the master device GSD files are usually supplied with a unit or can be downloaded from the Internet either
