module functions
Trainnet® Multifunction Vehicle Bus (MVB) modules are used to create vehicle buses or more comprehensive train communication networks. The Multifunction Vehicle Bus Module implements the MVB link layer functions of the IEC 61375-3-1 Train Communications Network standard. The TCN's real-time protocols and the routing between the MVB and other buses are implemented by the gateway CPU Module.
key features
The Trainnet® Multifunction Vehicle Bus module supports physical cable redundancy and full bus master functionality as specified in the IEC 61375-3-1 standard. Bus administrator redundancy is supported on the Software level.
TCN standard’s D-9 type connectors are located on the front panel of the module. Communication to the gateway is conducted through shared memory over the IEC 821 VME back plane bus. The MVB link layer functions are implemented by the MVB module's local processor. Multiple Trainnet® MVB modules can be controlled by a single Trainnet® CPU to implement physically separated MVB networks.
