Replacing the switchgear internal hard-wired connections by means of a high-speed
digital bus allows building new highly standardized switchgear with a more efficient
life cycle. Fast interlocking data among several REF 542plus units can be
exchanged on the CAN Open bus.
The utilization of the CAN Open bus is limited to the ABB switchgear
company. Stand alone devices may not be operated with theCAN Open
system.
In addition, the digital bus moves

closer to the process, allowing
the construction of switchgear systems with increased configuration and
maintenance flexibility. The CAN Open interface allows connecting any off-the-
shelf product compliant with the CAN Open standard, thus making the automation
capabilities of the REF 542plus almost unlimited.
The Fig. 4.11.-1 describes an architecture where two REF 542plus units and some
IO modules are connected with the CAN Open.

ABB Product Data Registration
The ABB Product Data Registration system is used to collect all the composition
information throughout the IED's life cycle and add them in ABB's data server.
ABB lifecycle services collects product data like product hardware, product
software, site information related to an IED. The firmware of each REF 542plus
terminal detects changes in the hardware composition or in the firmware. Thanks to
the existing history record technical support as well as services and repairs can be
provided by ABB as soon as possible.
