EtherCAT Communication
‑87‑
5.4 Networking Topology
After communication between the ECAT card and the AC drive is implemented, you
can connect the AC drive to the ECAT master station and configure related
parameters to implement communication between the ECAT card and the ECAT
master station, thereby implementing AC drive networking.
ECAT supports a variety of topologies, including bus, star, and tree topologies.
Different networking modes can be implemented by using switches.
