The WTB gateway dynamically adapts WTB communication to the train’s changing physical environment and tunnels communication between different vehicles. These function are required by the IEC 61375 and UIC556/557 standards.
The Sécheron Hasler Group IGW-450 family of products was developed to connect and ensure interoperability between multiple buses (WTB, MVB, CANOpen, Ethernet).
A PC-based SW configuration tool can be used to create the database needed to configure the IGW to operate on TCN networks. The IGW-450 supports the recommended TCN features including physical-layer or line redundancy and device redundancy with two notes per vehicle. It also implements UIC mapping.
