6.4.1
AMD5x
supports the EtherCAT protocol with ‘Servo Profile over EtherCAT’ (SoE). This protocol provides
deterministic communication over a standard 100Mbit/s (100Base-TX) Fast Ethernet (IEEE802.3) connection.
This makes it suitable for the transmission of control and feedback signals between the AMD5x and other
EtherCAT enabled controllers.
AMD5x functions as an EtherCAT slave controller, providing two ports (IN/OUT) for connection to other EtherCAT
compliant equipment. This allows nodes to be connected in many configurations such as a ring, star, or tree, with
EtherCAT’s self-terminating technology automatically detecting breaks or an intended end of line.
If only one port is used for EtherCAT operation, it must be the X1 (IN) port.
