B.2.4 DAISY CHAIN
A daisy chain is an interconnection of devices where each device is connected in series to the next.
With an Ethernet daisy-chain redundancy selected, the F650 has two Ethernet ports and it is working as an Ethernet
unmanaged switch. The two Ethernet ports are used for connecting each device to the ports of its two neighboring devices.
Each device in the daisy chain forwards the message until it reaches the destination.
Ports A and B use the same MAC (physical device) address and operate by chaining one device with the next one.
Note that it is important not to create a loop in this topology. Both ends of the chain can be connected to different
networks. The device operates only with one IP address through these 2 ports.
