Goals

TCNOpen goals are linked to the development projects currently in progress.

At the moment, there is one active project, started at the beginning of 2012 with the scope to develop a first open source implementation of the TRDP (Train Real-time Data Protocol) module.
A description of the TRDP module can be found here.

The standard specifying such module is IEC-61375-2-3 Communication Profile. Its position within the general TCN architecture is here highlighted.
The communication profile is a part of the Train Communication Network, which allows to achieve interoperability between Consist Networks (e.g. the Ethernet Consist Network defined in part 3-4) and the Ethernet Train Backbones defined in part 2-5.
