The Ethercat slave controller board is equipped with a Beckhoff IP core. The memory area of the Ethercat slave controller is mapped directly in the PCI Express address space. The 'Ethercat Slave Device' can be configured via 'esd Ethercat Master' or other masters. An Ethercat slave information file (ESI file in XML format) provided as an example is included in the scope of delivery. The slave API library and sample code enable rapid integration and development. To relieve the CPU from copying the output data to the host memory, the interface supports bus master DMA support. With support for MSI (Message Single Interrupt), the interface card is suitable for real-time operating systems such as VxWorks, RTX, RTX64 and others.
