Device Description File
A file containing configuration information about a device being a part of a
network that can be read out by masters for system configuration. Device
Description Files use various formats which 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.
Discrete Input
A “Discrete Input” (as defined in the Modbus terminology) is a single bit in
the memory which can be accessed using Modbus (read with FC 2).
DP
Decentral Periphery
DPM
Dual-Port Memory
EDS
Electronic Data Sheet
EDS file
A special kind of Device Description File used for example by EtherNet/IP.
EtherCAT
A communication system for industrial Ethernet designed and developed by
Beckhoff Automation GmbH.
Ethernet
A networking technology used both for office and industrial communication
via electrical or optical connections. It has been developed and specified by
the Intel, DEC and XEROX. 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.
EtherNet/IP
A communication system for industrial Ethernet designed and developed by
Rockwell. It partly uses the CIP (Common Industrial Protocol).
Ethernet Powerlink
A communication system for industrial Ethernet designed and developed by
B&R. It partly uses CANopen technologies.
FDL
Fieldbus Data Link defines the PROFIBUS communication on layer 2,
identical for DP and FMS
