D
DHCP
dynamic host configuration protocol. A TCP/IP protocol that allows a server to assign an
IP address based on a device name (host name) to a network node.
E
EDS
electronic data sheet. The EDS is a standardized ASCII file that contains information about a
network device communications functionality and the contents of its object dictionary. The EDS
also defines device-specific and manufacturer-specific objects.
EEPROM
Electrically Erasable Programmable Read-Only Memory. EEPROM is a nonvolatile memory.
EMC
electromagnetic compatibility. Devices that meet EMC requirements can operate within a system
expected electromagnetic limits without interruption.
Ethernet
A LAN wiring and signaling specification used to connect devices within a defined area, for
example, a building. Ethernet uses a bus or a star topology to connect different nodes on a
network.
Ethernet II
A frame format in which the header specifies the packet type, Ethernet II is the default frame format
for NIM communications.
EtherNet/IP
EtherNet/IP (the Ethernet Industrial Protocol) is especially suited to factory applications in which
there is a need to control, configure, and monitor events within an industrial system. The ODVA-
specified protocol runs CIP (the Common Industrial Protocol) on top of standard Internet protocols,
like TCP/IP and UDP. It is an open local (communications) network that enables the interconnec-
tivity of all levels of manufacturing operations from the office plant to the sensors and actuators on
its floor.
F
FeRAM
Ferroelectric Random Access Memory. FeRAM is a nonvolatile memory offering faster write
performance and greater number of writing cycles.
flash memory
Flash memory is nonvolatile memory that can be overwritten. It is stored on a special EEPROM
that can be erased and reprogrammed.
