During wiring, hold the registered jack of the RJ45 network cable and insert it in the
RJ45 port of the communication module until you hear a click sound. To remove the
RJ45 network cable, press and hold the tail of the registered jack, and pull it out
along the direction parallel with the module.
To avoid the influence of other stress on the communication cable and ensure the
stability of communication, fasten the cable near the equipment before starting
EtherCAT communication.
8.6.4 PROFINET Communication Wiring
After communication between the MD500‑PN1/MD500‑PN2 card and the AC drive is
implemented, connect the AC drive to the PROFINET master station and configure
related parameters. This can implement communication between the MD500‑PN1/
MD500‑PN2 card and the PROFINET master station, thereby implementing AC drive
networking.
PROFINET supports multiple types of topologies including the bus type, star type, and
tree type. Multiple types of networking can be achieved through the switch.
A ring or linear topology can be implemented by using two ports on the AC drive.
Connect the cable to only one of the two ports. The cable between two nodes is no
longer than 100 m in length.
8.7 Inspection After Wiring
After wiring is completed, inspect the items in the following table and tick compliant
items.
