Explanation
A component or device to which there is a wired connection.
Example: A 750-644 I/O module represented in WAGO-I/O-
CHECK on the operator PC.
A component or device to which there is no wired connection.
A remote device (from the perspective of the local device) or
the local device (from the perspective of a remote device).
Devices or components are in range when transmitter and
receiver are mutually so strong or sensitive that
communication is technically possible. Whether
communication actually occurs depends on several other
factors, e.g. if radio connection is even wanted or if security
settings are compatible.
For secure connections, communication is only possible with
devices defined as "authorized devices". Bluetooth
technology designates devices that view each other as
"authorized devices", as well as "paired" or "coupled".

Describes a Bluetooth
established. Sometimes it may not be possible for authorized
devices to connect to a Bluetooth
for example, when the device is designed or configured to
allow only a certain number of simultaneous connections and
that number has already been reached.
Describes a state in which devices are able to exchange data
with each other. To do so, the devices must be in range. If the
devices have a secure connection, the connection must be
between authorized devices.
Refers to the process of mutual verification of two Bluetooth
devices, where each device determines if the other is an
authorized device. Part of the process can be user interaction,
e.g. display of a dialog box on a smartphone or access to a
saved configuration that indicates which devices are and are
not allowed.
