7.1 EtherCAT Communication
EtherCAT is an open network communication between master and slave using real-time Ethernet
developed by Beckhoff and managed by ETG (EtherCAT Technology Group).
EtherCAT communication can be used by connecting an EtherCAT network card (LEC-S-NE) to the
LECSN-T driver.
The LECSN-T driver with an EtherCAT network card connected acts as a slave station compliant with the
CAN application protocol over Ether CAT (CoE) standard. The device type corresponds to a power drive
system and supports the CiA 402 drive profile.
