Issue Details

I am using the Sync model of CompactDAQ (cDAQ), CompactRIO (cRIO), or industrial controller and am utilizing Time Sensitive Networking (TSN). I need to purchase Ethernet switches that are TSN-compatible to use in my network.


National Instruments recommends working with Cisco switches with our TSN-enabled devices. Cisco supports TSN via the latest firmware update to their line of IE-4000 industrial switches. Any of the IE-4000 switches will work.

We recommend this model as it is the best match for the standard NI offering: IE-4000-8GT4G-E
This model provides:
  • 12 GigE ports (4 can be used with fiber optics)
  • TSN support (time sync and scheduled flows) on all 12 ports
  • Industrial temp and shock ratings
  • 24V redundant DC power inputs
These switches can be procured through standard Cisco channels. To find a distributor, use the Cisco Orders page. For more information and for questions on purchasing and using Cisco switches, please see the NI TSN Forum.

Once received, the firmware will need to be updated to the latest version. For details on selecting and installing the correct firmware for your switch please see Installing IOS SW TSN Support on a Cisco IE4000 Switch.

While NI recommends using the Cisco IE-4000 series switches, any switch that is 802.1AS compliant should be able to synchronize with National Instruments TSN-enabled devices.

Additional Information

If your application also requires deterministic data transfer, you will also need the centralized network configuration software (CNC). This CNC is not commercially released yet but we are working closely with Cisco to be able to provide NI customers with beta access to this software. Please contact NI via email CNCrequest@ni.com if you need to request access to this beta program. In the email please include your full name, company name, NI TSN controllers you will use in the system, and your NI sales representative's name.
