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.
Half duplex
Half duplex denominates a telecommunication system between two
communication partners which does not allow simultaneous, but
alternating, communication in both directions is called a half-duplex
telecommunication system. At such a system, receiving data inhibits the
transmission of data. Half-duplex is the opposite of _Full_duplex.
Hub
A network component connecting multiple communication partners with
each other. A hub does not provide own intelligence, thus it does not
analyze the data traffic and sends received data to all connected
communication partners. A hub can be used for setting up a star topology.
