2.3 Remote backplane
The main idea: Remote backplane for a rack system – in other words, the cable is the backplane. All modules are
connected to the uniform backplane (X2X Link). Directly connected X20, X67 or XV modules can each be placed
at a distance of up to 100 m outside the confines of the control cabinet. X2X Link guarantees the highest possible
level of resistance to disturbances based on twisted copper cables.
This not only provides a universal remote backplane which handles the communication between bus modules and
via the X2X Link cable, but makes it possible without converters or any loss in performance. A unique feature of
the X20 is the possibility to later integrate machine options on bus modules that are not yet being used without
having to change the software addressing.
Note:
A 100 m X2X Link cable is available from B&R for custom assembly (model number: X67CA0X99.1000).
