Most field busses use a twisted-pair cable
with differential voltage as physical medium. Errors
in a system’s user software are often blamed for operating
problems and reliability shortcomings in systems with
field busses. However, experience with the commissioning
of field bus systems indicates that most of the problems
found are due to inadequate cable types, improper installation
of the bus cabling system or faulty driver functions
of individual CAN Bus nodes.
Analyzing the physical bus system is the only way to
identify telegrams with a poor signal quality, so that
targeted action can be taken in order to eliminate defects
and implement improvements. This leads to enhanced signal
quality, reliable bus operation and resistance of the
bus to EMC influences. |
