About the EtherCAT Slave Interface
General Description
The EtherCAT Slave Interface for the Anybus X-gateway implements CANopen over EtherCAT, and
exchanges up to 512 bytes of data in each direction. The interface acts as a slave node, which means it
can be accessed by an EtherCAT master, but it will not initiate communication by itself.
The interface exchanges data through two buffers as follows:
•
Input Buffer
This buffer holds data forwarded
from the other network, i.e. data
which can be read by the Ether-
CAT master.
•
Output Buffer
This buffer is forwarded to the
other network, i.e. data which can
be written by the EtherCAT mas-
ter.
