EtherCAT®
MicroFlex e150 supports the EtherCAT protocol. This protocol provides deterministic
communication over a standard 100 Mbit/s (100Base-TX) Fast Ethernet (IEEE
802.3u) connection. This makes it suitable for the transmission of control and
feedback signals between the MicroFlex e150 and other EtherCAT enabled
controllers. EtherCAT's ‘CAN application layer over EtherCAT’ (CoE) capability allows
Mint to implement a drive protocol based on the CANopen DS402 Device Profile for
Drives and Motion Control.
MicroFlex e150 incorporates a built-in multi-port EtherCAT slave controller, providing
two ports for connection to other 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 E2 (IN) port.
