IP
Internet Protocol: Belongs to the TCP/IP family of protocols and is
defined in RFC791. It is based on layer 3 of the ISO/OSI 7 layer
model of networking and is a connectionless protocol, i.e. you do not
need to open a connection to a computer before sending an IP data
packet to it. Therefore IP is not able to guarantee that the IP data
packets really arrive at the recipient. On IP level neither the
correctness of data nor the consistence and completeness are
checked. IP defines special addressing mechanisms, see IP Address.
IP address
Identifies a device or a computer within an IP-based network and is
defined in the Internet Protocol Version 4 (IPv4) as a 32-bit number.
For ease of notation the address is usually divided into four 8-bit
numbers represented in decimal notation and separated by points:
a.b.c.d. Each letter stands for an integer value between 0 and 255,
e.g. 192.168.30.16. However, not all combinations are allowed, some
are reserved for special purposes. The IP address 0.0.0.0 is defined
as invalid.
Master
Type of device that initiates and controls the communication on the
bus
netX
networX on chip, Hilscher network communication controller. High
integrated network controller with optimized system architecture for
communication and maximum data transfer.
PROFINET
Communication system for Industrial Ethernet designed and
developed by PROFIBUS & PROFINET International (PI) which uses
some mechanisms similar to those of the PROFIBUS field bus
PROFINET IO
PROFINET IO (Input - Output) has been created for the connection of
remote peripheral to a controller
PROFINET IO-Device
PROFINET field device that cyclically receives output data from its
IO-Controller and responds with its input data
Real-Time Ethernet
Extension of the Ethernet networking technology for industrial
purposes with very good Real-Time features and performance also
named as 'Industrial Ethernet'. There is a variety of different Real-
Time Ethernet systems on the market, which are incompatible with
each other. The most important systems are: EtherCAT, EtherNet/IP,
POWERLINK, Open Modbus/TCP, PROFINET, Sercos, VARAN.
RJ45
A connector type often used for Ethernet connection. It has been
standardized by the Federal Communications Commission of the
USA (FCC).
Slave
Type of device that is configured by the Master and which then
performs the communication
Switch
Intelligent network component connecting multiple communication
partners (or even entire branches of a network) with each other,
capable to analyze the network traffic in order to decide on its own
and shows transparent behaviour to connected communication
partners
SYNC
Sychronisation Cycle of the Master
