Wide Choice of Hardware Designs
The CAN-PCIe/402 is a PC board designed for the PCIe bus that features one, two (CANPCIe/402-2) or four (CAN-PCIe/402-4/2Slot) electrically isolated CAN High-Speed interfaces according to ISO 11898-2. The CAN-PCIe/402-4/2Slot comes with two CAN interfaces via a separate slot bracket. These product versions are also available without electrical isolation. In the CAN-PCIe402-B4/1Slot version all four CAN interfaces are connected via one 37-pin DSUB connector. Equipped with up to two CAN interfaces the board is available as low profile versions (CAN-PCIe/402-1-LP and -LP2).
CAN Data Management
The independent CAN nets according to ISO 11898-1 are driven by the esdACC (esd Advanced CAN Core) implemented in the Altera FPGA. The FPGA supports bus mastering (first-party DMA) to transfer data to the host memory. This results in a reduction of overall latency on servicing I/O transactions in particular at higher data rates and a reduced host CPU load.
Due to the usage of MSI (Message Signaled Interrupts) the CAN-PCIe/402 can be operated for example in Hypervisor environments.
The CAN-PCIe/402 provides high resolution hardware timestamps.
CAN layer 2 (NTCAN-API) software drivers are available for Windows, Linux, VxWorks, QNX, RTX and RTX64. The CANopen software package is available for Windows, Linux, RTX, VxWorks and QNX. Drivers for other operating systems are available on request.
