AKD EtherCAT | 4 EtherCAT Profile
4.1 Slave Register
The table below gives the addresses of individual registers in the FPGA memory. The data is
provided in little-endian format, with the ’least significant byte’ occupying the lowest address.
A detailed description of all registers and FPGA memory locations is available in the “Ether-
CAT Slave Controller” description of the EtherCAT user organization (www.EtherCAT.org).
