Integration of CAN buses into existing Ethernet technology
Use as a universal PC CAN interface and for coupling CAN networks via Ethernet
The CAN Ethernet Gateway enables the integration of CAN buses into an existing Ethernet topology. It is therefore suitable both as a universal PC CAN interface and for coupling CAN networks via Ethernet. CAN messages are transmitted directly at layer 2 level and are therefore protocol-independent . This allows the CAN Ethernet gateway to be used for various high-layer protocols, such as CANopen, DeviceNet or SDS. Access via Ethernet is possible via TCP as well as UDP.
The CAN Ethernet Gateway is based on a powerful ARM9 controller, which guarantees a high data throughput even with several simultaneously active CAN interfaces. By using Linux as the operating system, users can run their own programmes in parallel with the gateway application. Sophisticated filter and trigger mechanisms enable user tasks to be called up directly on the gateway as a targeted response to specific events.
Easy-to-configure filters ensure a sensible restriction of the CAN messages to be transmitted. Each CAN message is assigned a time stamp , which ensures time transparency during message transmission. The CAN Ethernet Gateway can manage several Ethernet connections simultaneously , thus enabling the creation of complex network structures.
The device can be configured either via Ethernet or USB.

Gateway mode
Gateway mode allows the device to be used as a universal CAN/Ethernet coupler. Typically, the gateway is used as an external CAN interface on a PC, thereby enabling simple and flexible access to CAN systems via a LAN or the Internet. The drivers included in the scope of delivery enable the CAN-Ethernet gateway to be used as a PC interface for all CAN and CANopen software tools distributed by SYSTEC. The comprehensively documented driver API also supports the integration of the gateway into custom user applications. Message exchange with the CAN network takes place from the host application via socket-based TCP or UDP communication.
Bridge mode
Bridge mode enables the transparent interconnection of CAN networks via LAN or the internet. By filtering messages, it is possible, on the one hand, to limit the volume of data to be transmitted and, on the other hand, to selectively control the data exchange between the sub-networks. For example, when interconnecting CANopen networks, it is possible to exchange only PDOs and exclude all other message types from being forwarded.
