The onboard 100 MHz oscillator automatically synchronizes to other network-synchronized devices that are part of the local IEEE 802.1AS or IEEE 1588-2008 subnet, depending on the active time reference that is being used on the controller.

The following timebases are derived from the onboard oscillator and are synchronized to it:

  • 80 MHz
  • 40 MHz
  • 20 MHz
  • 100 kHz
  • 13.1072 MHz
  • 12.8 MHz
  • 10 MHz

Therefore, the timebases are also synchronized to other network-synchronized timebases on the IEEE 802.1AS or IEEE 1588-2008 subnet. This enables analog input, analog output, digital I/O, and counter/timers to be synchronized to other chassis across a distributed network.

When programming C Series modules in FPGA mode, you can use the Time Synchronization IO Nodes to synchronize the LabVIEW FPGA application to other network-synchronized devices.
