C
Channel
A channel is a mechanism or resource that enables data transmission over space or
time.
Channel map
The channel map defines for a quantity of available channels the portion thereof
that is to be used or not used. This makes it possible to reserve certain frequencies
for transmission by other devices or technologies.
Checksum
The formation of a checksum is used to recognize errors in data transmission or
storage. There are different methods of forming a checksum. Usually, redundant
bits calculated from the report itself are attached to a report. These bits are
calculated again after data transmission and compared to the checksum.
CoD
(Class of Device)
The Bluetooth
standard device type (such as mobile phone or hands-free calling kit) a Bluetooth
device corresponds. Vendor-specific types may also be used in addition to
standard types.

Communication
For this I/O module: In "Communication" mode of the 750-644 I/O module, data
is exchanged cyclically with connected Bluetooth
Configuration
Operating mode of the 750-644 I/O module, in which the I/O module can be
configured. In this mode, no data is exchanged with other devices. However,
Bluetooth
Connection
Presence of at least one transmission channel between devices that communicate
with each other.
Control byte
For this I/O module: A specific byte of the cyclic process image output (PIO)
containing protocol information for acyclic services (register communication,
parameter channels).
C/S byte
(Control/Status byte)
See "Control byte" and "Status byte"
