ECS-M.2/FPGA PCI Express® EtherCAT® SubDevice Interface in M.2 Form Factor DC Sync and Latch Signals For system synchronization, the EtherCAT Distributed Clock signals (2x Sync, 2x Latch I/Os) are provided as physical I/Os via breakout adapter. Convert your Embedded System into an EtherCAT SubDevice • Add EtherCAT SubDevice (ECS) functionality to your embedded PC • The EtherCAT SubDevice Controller address space is directly mapped to the PCI Express address space. • M.2 form factor 2280 or 2260 for smaller embedded devices like IPCs or Raspberry Pi Simple Configuration and Rapid Application Development • Easy configuration by esd's EtherCAT MainDevice or other MainDevices • Sample EtherCAT SubDevice Information File (ESI file in XML format) is provided • esd's EtherCAT SubDevice API library and sample code for rapid application development are included EtherCAT SubDevice Interface for PCIe The ECS-M.2/FPGA is an EtherCAT SubDevice in M.2 form factor. It is based on a Beckhoff IP core implemented in an Altera® FPGA, configured with 8 FMMUs, 8 Sync Managers, 60 kB DPRAM, and 64-bit Distributed Clocks. Two EtherCAT ports (IN/OUT) are available via FFC connectors on the board edge and can be connected to RJ45 sockets using the supplied breakout adapter. Bus Master Support • The FPGA contains Bus Master DMA support to offload the CPU from copying the output process image data into the host memory. This is utilized by the esd EtherCAT SubDevice Stack. Versatile Application The module supports standard EtherCAT protocols including CoE, FoE, and EoE, enabling the PCI Express host system to operate as a flexible EtherCAT I/O node accessible by the MainDevice. Customization on Request • Customized configurations are available on request.
