NTOnTrack TCN/TRDP Conformance Test

The NTOnTrack TCN/TRDP Conformance Test is dedicated for End Devices using TRDP as a communication protocol within the Train Communication Network (TCN) according to IEC 61375-2-8.

The Conformance Test shall verify that the implementation/integration. e.g. of a TRDP protocol stack, into a custom device is realized in a way that the specific device behaves in conformance with the above standard.

It includes checks of Transport Layer, PD/MD communication patterns, addressing, PD/MD-PDUs, topography counters and reaction to faults.

A detailed conformance “Test Specification” is the basis for the “Test System” running the “Test Scripts”. They interact with the “Test Application” implemented on the “Item under Test” (IuT).

The final Test Report then states the conformance.

Scope of Services

• Detailed Conformance Test Specification
• Conformance Test Report
• PICS proforma template
• Sample Code in C for the Test Application for Item under Test (IuT)
• Test execution independent of the TCN Open TRDP stack
• Support of test iterations

Customer benefits

• Reliable, reproducible testing of different end devices (independent of operating systems) in accordance with IEC 61375-2-8
• TCNOpen independent testing of implementation
• Individual set of test cases (according to PICS)

More details

The conformance tests are executed on the test system and stimulate and check the IuT. Therefore a provided “Test Application” is executed on the IuT to respond to the
test system commands.

The IuT “Test Application” is a module for the interpretation of the different test cases from the test system. It can be implemented in the programming language C.

The PICS proforma determines which features are supported by the IuT and which category of tests will be executed.
