CAN-Ethernet Gateway V2


The CAN-Ethernet Gateway enables the integration of CAN buses to existing Ethernet topology. Hence, it is suitable as universal PC CAN interface and for coupling of CAN networks via Ethernet. CAN messages are directly transferred on layer 2 level - independently from protocol. This allows for applying the CAN-Ethernet Gateway to high-layer protocols such as CANopen or DeviceNet. The access via Ethernet is possible over TCP and UDP.

The CAN-Ethernet Gateway is based on a high-performance ARM9 controller which provides for a high data throughput even if several CAN interfaces are simultaneously active. Using Linux as operating system enables the user to execute own programs in parallel to the Gateway application. In targeted answer to certain events, sophisticated filter and trigger mechanisms allow for directly calling user tasks on the Gateway.

Filters are easily configurable and ensure reasonable limitation of CAN messages to be transferred. Each CAN message is allocated a time stamp that assures time transparency for the message transfer. The Gateway is able to administer several Ethernet connections simultaneously. Thus, it is possible to create complex net structures.

The device configuration optionally takes place via Ethernet or via USB.

Operating Modes

Gateway mode

The Gateway mode makes it possible to use the device application as a universal CAN / Ethernet coupler. Thereby, the Gateway is typically used at a PC as external CAN interface. Hence, it enables easy and flexible access to CAN systems via LAN or Internet. The scope of delivery includes drivers that facilitate using the CAN-Ethernet Gateway as PC interface for all CAN and CANopen software tools sold by SYS TEC. The driver API is documented in detail and supports the integration of the Gateway into own user applications. From the Host application, the message transfer with the CAN network takes place via socket-based TCP or UDP communication.

Bridge mode

The Bridge mode allows for transparent coupling of CAN networks via LAN or Internet. By filtering messages, on the one hand it is possible to limit the data volume to be transferred, and on the other hand it is possible to systematically control the data exchange between subnets. For example, for the coupling of CANopen networks it is feasible to only exchange PDOs and to exclude all other message types from being transferred.
