Wide Feature Set: Gateway and Bridge for Ethernet to CAN Bus
- Secure and autonomous CAN-to-CAN bridge via encrypted TCP/IP connection by connecting two EtherCAN/3-FDs
- Sophisticated on device CAN ID based filter and forwarding mechanisms to minimize Ethernet bandwidth and/or host CPU usage
- Receive and send CAN data with any network device using the lightweight Ethernet Low Level Socket Interface (ELLSI) protocol
- Monitoring of CAN bus with an arbitrary TCP based server for customized postprocessing tasks
- Support for non-interfering CAN bus monitoring
Easy to Use with robust Communication
- Integrated web interface for an easy device configuration without additional configuration software
- Protection via mechanical switch that deactivates the web server to minimize the device’s attack surface and to prevent unwanted reconfiguration
- Robust communication thanks to TCP/IP support
Remote CAN Interface as Virtual Device
- Transparent integration of the remotely connected CAN buses into the esd NTCAN environment on Windows and Linux
- Use of existing NTCAN API based applications, protocol stacks and established CAN tools, such as CANreal on Windows
Usage as Gateway or Bridge
The EtherCAN/3-FD enables remote access to CAN FD or CAN CC buses via Ethernet. Three different modes of operation allow a versatile integration of a CAN bus into a system with LAN connectivity, i.e. EtherCAN mode or platform-independent client or server modes. Furthermore, two EtherCAN/3-FD gateways can operate autonomously in a bridge mode to seamlessly connect two CAN networks via Ethernet.
Ethernet and CAN FD Interfaces
The EtherCAN/3-FD features one (10/100 Mbit/s) Ethernet interface and two galvanically isolated CAN FD ports for bitrates from 10 Kbit/s up to 8 Mbit/s. CAN FD is downward-compatible to the CAN 2.0 A/B standard, so the device can be integrated in any CAN CC based net.
CAN bus access with EtherCAN/3-FD: EtherCAN-, Server- and Client-Mode
EtherCAN Mode
The EtherCAN technology developed by esd enables the NTCAN API based access to a CAN bus remotely connected via LAN in the same way as the access via a local CAN interface. A single EtherCAN/3-FD can be connected to different hosts and/or different applications on the same host. The EtherCAN mode is supported on Windows® and Linux®.
Plattform-independent Server Mode
The EtherCAN/3-FD supports the open, proprietary, UDP and TCP based EtherCAN Low Level Socket Interface (ELLSI) protocol, so a CAN bus can be controlled and accessed from any UDP or TCP capable device. Example C source code of ELLSI client implementation provided as part of the SDK. S7-300/400 function blocks with ELLSI support on request.
Plattform-independent Client Mode
The EtherCAN/3-FD streams all received CAN data to a server for custom storage, post-processing and visualization. The communication is based on an open TCP based network protocol.
Secure CAN-to-CAN connection via LAN with EtherCAN/3-FD: TCP data exchange and sophisticated filter mechanisms
Bridge Mode
With two EtherCAN/3-FD modules this operation mode allows to connect two CAN networks via LAN. The data is exchanged via TCP with optional TLS encryption. To minimize the exchanged data the device supports sophisticated filter mechanisms.
Free CAN tools for fast setup and diagnosis of CAN networks
Our CAN tools for Windows, which are available free of charge in the CAN SDK, significantly support the user in quickly setting up and easily diagnosing CAN, CAN FD and CANopen networks. The possibility of data logging helps the user to record the data traffic for later analysis and to process it further as a CSV file.
