Hardware

  • cRIO-9049
  • cRIO-9045
  • cDAQ-9185
  • cDAQ-9189
  • cRIO-9057
  • cRIO-9054

Issue Details

TSN is a series of features being added to the Ethernet standards (IEEE 802).  This includes:

• Mechanisms for time synchronization (IEEE 802.1AS)
• Mechanisms for using coordinated time to schedule traffic (IEEE 802.1 Qbv)
• Mechanisms to assure simple/scalable system configuration (IEEE 802.1 Qcc)

However, when I review documents about TSN for TSN-enable cDAQ and TSN-enable cRIO, I only see information about 802.1AS. Can we utilize the other features with just cRIO and cDAQ?

Solution

No, you cannot fully utilize all features of TSN with just cRIO and cDAQ. To maximize the benefits of specific TSN features, you need compatible TSN-enabled Ethernet switches. For instance, to support profiles like IEEE 1588 or 802.1Qbv, it is recommended to use switches such as the Cisco IE-4000-8GT4G-E model. This ensures proper time synchronization and priority control across the network.
