PROFINET Communication
‑65‑
4.4 Networking Topology
After communication between the PN card and the AC drive is implemented, you can
connect the AC drive to the PROFINET master station and configure related
parameters to implement communication between the PN card and the PROFINET
master station, thereby implementing AC drive networking.
PROFINET supports a variety of topologies, including bus, star, and tree topologies.
Different networking modes can be implemented by using switches.
