B.1 General Section
Baud rate
–> transmission rate
Broadcast
A broadcast is like ”calling all stations”: Using one broadcast frame, you can re-
ach all nodes that are prepared to accept broadcast frames.
Bus segment
Part of a –> subnet. Subnets can consist of bus segments and connectivity devi-
ces such as repeaters and bridges. Segments are transparent for addressing.
Client
A client is a device or, in general terms, an object that requests a service from a
–> server.
Configuration data
Parameters that determine the modes and functions of a–> CP. They are set and
downloaded using the NCM S7 configuration tool.
CP
Communications Processor. Module for communications tasks.
CSMA/CD
CSMA/CD (Carrier Sense Multiple Access with Collision Detection)
Frame
A message from one PROFIBUS/Ethernet station/node to another.
Frame header
A frame header consists of an identifier for the –> frame and the source and de-
stination address.
Frame Trailer
A frame trailer consists of a checksum and the end identifier of the –> frame.
