Real time data transfer:
the recipient returns an immediate
confirmation of each instruction
within
the bus cycle
Speed:
high data transfer rates, higher
sampling rate, higher performance
and improved quality
Automatic addressing:
minimal network planning
and administration costs
Hot plug in:
participants can be added or
removed during operation
High reliability:
instructions are immediately
repeated
within a bus cycle when an error
occurs |
Open standard:
open VARAN technology that
can
be used by anyone
Direct access:
immediate access: high priority
can
be given to the participant (additional
to standard, isochronous and
asynchronous data transfer)
Simple implementation:
even in small sensors/actuators
Simple programming:
for the bus manager, the bus
system
represents a large memory system
in
which each participant is assigned
an
area. So simple read/write instructions
are possible |
Low implementation costs:
inexpensive standard components
are used
System consistency:
Standard TCP/IP cross traffic
possible
Simple maintenance and service:
with comfortable service and
diagnostic tools
Reusableness of developments:
CANopen over VARAN allows to
reuse
already developed source codes
