IP
Internet Protocol: Belongs to the TCP/IP family of protocols and is
defined in RFC791 (available on http://www.ietf.org/rfc/rfc791.txt). 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 addresse
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.
Open Modbus/TCP
Communication system for Industrial Ethernet designed and
developed by Schneider Automation and maintained by the Modbus-
IDA organization based on the Modbus protocols for serial
communication
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
