Recommended network topology with safety peer communication
In the ControlEdge HC900 system where safety peer communication is required, it is recommended to
have separate peer communication network and add port filtering of peer protocol (UDP port 502) on host
communication switch. This ensures that the safety peer communication network is separate from the host
network communication.
