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
Firmware
Software running inside a device providing the basic functionality of this
device. The firmware is stored remanently in the flash memory circuit of the
device. It can be updated by a firmware download.
Full duplex
Full duplex denominates a telecommunication system between two
communication partners which allows simultaneous communication in both
directions is called a full-duplex telecommunication system. At such a
system, it will be possible to transmit data even if currently data are
received. Full-duplex is the opposite of Half_duplex.
Function code
A function code (FC) is a standardized method to access, i. e. read or write
on coils (Bits) or registers via Modbus.
Modbus function codes are elements of Modbus request/reply telegrams.
GSD
Generic Station Description, Device description file
GSD file
A special kind of Device Description File used by PROFIBUS (GSD =
Generic Station Description).
GSDML
Generic Station Description Markup Language
XML based device description file.
GSDML file
A special kind of XML-based Device Description File used by PROFINET.
