Bit Strobe
A Bit Strobe I/O connection is a connection between a DeviceNet client and an
undetermined number of servers, these being queried by commands sent by
the client.
Bonding strap
Flexible conductor, normally braided, that joins inactive components, e. g. the
door of a switchgear cabinet to the cabinet main body.
Bus
Bus system for data exchange, e. g. between CPU, memory and I/O levels. A
bus can consist of several parallel cables for data transmission, addressing,
control and power supply.
Bus cycle time
Time required for a master to serve all slaves or stations in a bus system, i. e.
reading inputs and writing outputs.
Bus line
Smallest unit connected to a bus, consisting of a PLC, a coupling element for
modules on the bus and a module.
Bus system
All units which communicate with one another via a bus.
Capacitive coupling
Electrical capacitive couplings occur between cables with different potentials.
Typical sources of interference are, e. g. parallel-routed signal cables, contac-
tors and electrostatic discharges.
Class
A group of Objects that all describe the same system components. All Objects
of a Class are identical in form and behavior, they can though contain different
attributes.
COB
Communication Object, which is made of one or more CAN frames. Any infor-
mation transmitted via CANopen has to be mapped into COBs (Source: CiA
DS 401 V2.1).
