In real circumstances of train operation, changing the train composition and orientation of Consists is a common operation. To ensure the interoperability between onboard systems, IEC 61375 has defined a standard Train Communication Network (TCN) implementation.
The TCN defined in IEC 61375 sets the basis for interoperability between trains by defining how the Backbone Network should be implemented. The purpose of the Backbone Network is to transmit information through the entire train; by means of a specific protocol, such information defines the train composition and the orientation of each consist (Train Inauguration).
Moreover, the IEC 61375 defines the application profiles of the TCN in order to achieve communication between software applications throughout consist networks and the train backbone.
VDS Rail's Train Backbone Nodes and Integrated Train Backbone Nodes have been specifically designed to comply with the norm. Both devices are equipped with inbuild TTDP protocol, TRDP protocol, and the IEC 61375-2-3 full Communication Profile.
