XMC EtherCAT® Slave Interface
Convert your XMC System into an EtherCAT Slave Device
Add EtherCAT Slave (ECS) functionality to your XMC equipped base board
The EtherCAT Slave Controller address space is directly mapped to the PCI Express® address space.
Simple Configuration and Rapid Application Development
Easy Configuration by esd's EtherCAT Master or other masters
Sample EtherCAT Slave Information File (ESI file in XML format) is provided
esd's EtherCAT Slave API library and sample code for rapid application development are included
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 Slave Stack.
esd is a member of the EtherCAT Technology Group (ETG).
EtherCAT Slave Interface for XMC
The ECS-XMC/FPGA is an EtherCAT Slave Controller board in a VITA 42.3 (XMC) form factor. It utilizes a Beckhoff IP-Core which is implemented in an Altera FPGA and configured for 8 FMMUs, 8 Sync Managers, 60 kB DPRAM and 64 bit Distributed Clocks. Other Configurations are available on request. The FPGA connects between the PCI Express bus on the XMC P15 connector and the two Ethernet interfaces on the front panel. The additional EtherCAT signals SYNC and Latch are available on the secondary XMC connector P16, soldering pads or optionally on the PMC I/O connector P14.
Because of this simple hardware topology and the use of a “soft” controller the design offers a maximum of flexibility. The XMC system can act as an I/O node. An EtherCAT master can use several EtherCAT protocols like CoE, FoE and EoE to communicate with this EtherCAT slave device.
SYNC/Latch I/Os and Share I/Os
Via connector XMC-P16 equipped on the ECS-XMC/FPGA 20 3.3 V LVTTL I/Os are available, including the signals from the EtherCAT Slave Controller: 2x Sync and 2x Latch. On request the 20 XMC I/Os can be configured as 10 I/Os with 2.5 V level LVDS.
Device drivers for Windows® and Linux® with documentation and EtherCAT slave examples are included in the scope of delivery. Drivers for other operating systems, especially real-time operating systems, are available on request.
The EtherCAT Slave card is also available with PMC interface (ECS-PMC/FPGA; order no. E.1104.02) or with PCI Express® interface (ECS-PCIe/FPGA; order no. E.1106.02). The PCIe card is also available as low profile version (ECSPCIe/FPGA-LP; order no. E.1106.04).
