Glossary
Gateway
This is a device that is connected to more than one physical TCP/IP network and can
forward or distribute IP packets. A gateway translates various transport protocols or data
formats (for example IPX and IP) and is included in networks mainly because of this
translation function. Gateways are also known as IP routers.
Host name
The DNS name of a device on a network. These names are used to locate a computer in the
network. Before a computer can be found, its host name must be listed in the host file or be
known to a DNS server. On most computers running Windows, the host name and computer
name are identical.
HR
HR stands for the resolution 1024x768 pixels (width to height ratio 4:3, 12:9) regardless of
other parameters.
Ident profile
Implementation of the "Proxy Ident Function Block" (PIB) from PROFIBUS INTERNATIONAL
for SIMATIC S7. Synonym of RFID standard profile.
IP address
A 32-bit address to identify a node in an IP network. Each node in the IP network is be
assigned a unique IP address. This consists of the network ID and a unique host ID. This
address is typically represented with the decimal value of each octet separated by a period
(for example, 192.168.7.27). In this version of Windows, you can configure a static IP
address or have it assigned dynamically by DHCP.
Ladder diagram
Graphic representation of the control functions based on circuit diagrams from contactor
technology. The current paths are arranged horizontally one below the other and the
symbols used are different.
MAC address
The MAC address is the hardware address for each network device (network card, switch ,
etc.) and is used for unique identification of the device in the network. The MAC address is
burned into a chip and cannot normally be modified.
Main ROI or ROI
Region of Interest. The main ROI is the area with characteristics of the specimens relevant
for image processing.
