Glossary

A
Ad-hoc
(lat. for "to this")
An ad-hoc network refers to a wireless network topology in information
technology between two or more end devices that manage without a fixed
infrastructure.
For this I/O module: "Ad-hoc Communication" mode is one of 3 operating modes
that the 750-644 I/O module supports. In "Ad-hoc Communication" mode,
communication is also possible with Bluetooth
manufacturers.
AFH
(Adaptive Frequency Hopping)
The adaptive frequency hopping process is used to temporarily skip faulted or
occupied sections of the total available frequency band and use other channels.
Allowed device
Device with which a connection can be established. Devices not included in this
category cannot connect.
Application
An application is a computer program developed by the user.
ASCII
(American Standard Code for Information Interchange)
The basis for character set coding. Character encoding defines 128 characters,
consisting of 33 non-printable and 95 printable characters. Each character is
assigned a bit pattern consisting of 7 bits. Since each bit can have two values, a
total of 27 (= 128) different bit patterns exist, which can be interpreted as whole
numbers 0–127 (hexadecimal 00–7F).
Authentication
Authentication is a process for testing the identity transmitted by a communi-
cation partner.
Available device
Device, that is physically in range and ready to connect and ready for use.
B
Baseband
A baseband is referred to if the desired signal is transmitted in an unaltered
frequency range. In wireless communication systems, wireless transmission does
not usually take place in the baseband, but rather by modulation of a significantly
higher frequency carrier signal with the baseband signal.
