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.
