9.4 Glossary
Baud rate
Data transmission speed of a communication channel or interface.
Boot loader
Program loading the firmware into the memory of a device in order to be executed.
Device Description File
A file containing configuration information about a device being a part of a network that can
be read out by the master for system configuration. Device Description Files use various
formats that depend on the communication system.
DHCP
Dynamic Host Configuration Protocol. This is a protocol simplifying the configuration of IP
networks by automatically assigning IP addresses.
DP
Decentralized Periphery
DPM
Dual-Port Memory
DTM
The Device Type Manager (DTM) is a software module with a graphical user interface for
the configuration or for diagnostics of device.
Ethernet
A networking technology used both for office and industrial communication via electrical or
optical connections. It provides data transmission with collision control and allows various
protocols. As Ethernet is not necessarily capable for real-time application, various real-time
extensions have been developed.
FDL
Fieldbus Data Link defines the PROFIBUS communication on layer 2, identical for DP and
FMS
FDT
Field Device Tool (FDT) specifies an interface in order to be able to use DTM (Device Type
Manager) in different applications of different manufacturers.
Firmware
Software providing the basic functionality of this device. The firmware is stored permanently
in the flash memory circuit of the device. It can be updated by a firmware download.
GSD / GSE
Generic Station Description / English, Device description file
GSD file
A special kind of Device Description File used by PROFIBUS (GSD = Generic Station
Description).
