ESD Electronics (Germany) offers the EtherCAN/2 CAN-to-Ethernet gateway based on the 200-MHz ARM9 micro-controller (MCU). The module is designed for hat-rail mounting in a control enclosure as a backward compatible replacement for the company's EtherCAN gateway.
THE DEVICE PROVIDES AN ETHERNET INTERFACE (10/100 Mbit/s, RJ45 connector) and an electrically isolated high-speed CAN interface (ISO 11898-2) supporting bit-rates up to 1 Mbit/s. The CAN connection is done via a 5-pin open style connector with pinning according to the CiA 303-1 recommendation. The module dimensions 22 mm x 112 mm x 113 mm and operates at temperatures from 0 °C to +70 °C and at maximum 90 % humidity. The power supply may range from 18 VDC to 32 VDC.
The gateway has a build-in HTTP server, which allows web-based configuration and maintenance. Diagnostic events and messages during run-time may be optionally indicated using the “syslog” protocol or by sending an email. The gateway firmware may also be updated via the web interface. Also supported is the Simple Network Management Protocol (SNMP).
rivers for Windows and Linux operating systems are available, which integrate the CAN gateway as a virtual CAN device on the host, programmed via the NTCAN-API available for all company's CAN adapters. This allows using the applications, CAN protocol stacks (CANopen, J1939, etc.) and tools (CAN SDK, CANreal, etc.) available for the host platform. In addition, the gateway supports the UDP-based disclosed and documented Ethernet Low Level Socket Interface (ELLSI) protocol for host platforms, which are currently not covered with a dedicated driver.
