TA protocol for the transmission of status information and error messages of
the IP, TCP and UDP protocols between IP network nodes. ICMP offers,
among others, the possibility of an echo (ping) request to determine whether
a destination is available and is responding.
IEEE
Institute of Electrical and Electronic Engineers.
IEEE 802.3
IEEE 802.3 is a IEEE standard. ETHERNET only supports the yellow cable
as a medium. IEEE 802.3 also supports S-UTP and wideband coaxial cable.
The segment lengths range from 500 m for yellow cable, 100 m for TP and
1800 m for wideband coaxial cable. A star or a bus topology is possible.
ETHERNET (IEEE 802.3) uses CSMA/CD as a channel access method.
Intel format
Set configuration of the fieldbus coupler / controller to establish the process
image. In the coupler/controller memory, the module data is aligned in
different ways, depending on the set configuration (Intel/Motorola-Format,
word-alignment,...). The format determines whether or not high and low
bytes are changed over. They are not changed over with the Intel format.
Internet
A collection of networks interconnected to each other throughout the world.
Its most well known area is the World Wide Web.
Intranet
A network concept with private network connections over which data can be
exchanged within a company.
IP
Internet Protocol. The connectionless network layer, which relies on upper
protocols to provide reliability.
ISO/OSI- Reference Model
Reference model of the ISO/OSI for networks with the objective of creating
open communication. It defines the interface standards of the respective
software and hardware requirements between computer manufacturers. The
model treats communication removed from specific implementations, using
seven layers.
