How to get TSN Switches

Applications performing synchronized measurements may be able to use the built-in switches in the CompactDAQ chassis to meet their networking needs.  Additionally for simple distributed control applications, two cRIO or Industrial Controllers can be directly connected and all the TSN features can be used.  However, many applications will require additional Ethernet switches supporting TSN.  Eventually there will be multiple standard switches on the market that can support TSN features and we are working with multiple switch vendors through Avnu to assure that selection and validation of these switches is straight forward.


To help facilitate building systems while the market is ramping, we are working with Cisco to provide access to their TSN enabled switches and configuration software.  Cisco supports TSN via the latest firmware update to their line of IE4000 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:



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 you can use this link:

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 the following link:

If your application also requires deterministic data transfer then 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 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 name.
