 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
Reusability of software components:
CANopen® over VARAN allows to reuse
already developed source codes
