CAN Vehicle Bus Interface Module
The EKE-Trainnet® CAN Vehicle Bus Interface module (CVB) is used to create up to two CAN Buses in the train.
The two CAN ports can be independently configured as CAN 2.0 A/B or CANopen®. The EKE-Trainnet® CVB module implements the CAN link layer functions. The routing between the CAN bus and other buses are implemented by the gateway Central Processing Units (CPU) module.
Key Features
The module has two CAN network connectors on the front panel, one 9-pin sub-miniature D-type connector for each independent interface. Communication to the gateway is done through shared memory over the IEC 821 VME back plane bus. The CAN link layer functions and CAN network access are implemented with the local CPU of the CAN module. Multiple EKE-Trainnet® CVB modules can be controlled by a single EKE-Trainnet® CPU to implement physically separated CAN networks.
The EKE-Trainnet® CVB module has static shared RAM memory accessible from both the local CPU and the VME Bus interface. The CVB module is realised through a highly efficient combination of local microprocessor and FPGA logic. The EKE- Trainnet® CAN Vehicle Bus Interface Module has the capability of carrying out some specific diagnostics functions. Interfaces are Dual CAN 2.0 B and ISO 11898 compatible with a CiA DS-102 standard pin.
Options
The EKE-Trainnet® CVB module is available as an option with integrated bus termination resistors.
