TCNOpen general objective is to provide a suitable environment, the Open Interest Group, where partner companies can collaboratively develop new components conformant to the TCN standard.

For each component, a specific Open Source Project will be started, which will run through all required phases: specification, development, test, support.

A first project is currently in progress, related to the development of the TRDP module.

TRDP (Train Real-time Data Protocol) is an intermediate module between the TCP or UDP protocols and the applications using the network.
It can optionally include an additional safety layer (SDT). SDT is an end-to-end protocol over an untrusted communication channel.
SDT fulfills IEC62280 (EN50159) and supports the transmission of safety related data between a safe data source and one or many safe data sinks.
