Host

Networking
Redundant Link (optional)

External

Switch

Advantages:
•

Unpowered nodes and/or node failure does not disrupt network communication with
other nodes

•

Failure of any single Ethernet cable does not disrupt network communication when you
have a redundant link

•

Additional nodes or heavier network traffic affects network performance less than the
other topologies

•

Simple installation, expansion, and troubleshooting

Note

 

Network configuration and programming require careful consideration. Visit 

ni.com/info

 and enter 

fdenet

 for information about exploiting link redundancy and

automatically improving reliability.

Disadvantages:
•

Most costly of the recommended topologies

•

Requires an external switch (external IEEE 802.1AS switch for network synchronization)

•

Covers the least distance

Note

 

For information about daisy-chaining power, refer to 

Power Connectors and

Wiring

.

External Switch Requirements

To meet the minimum requirements for successful operation with FieldDAQ devices, any
switch directly connected to the FieldDAQ device should be compliant with IEEE 802.1Q
bridges and bridged networks.
