Automatically synchronize acquisitions between systems across an ethernet network.
Synchronization-enabled devices use the IEEE 802.1AS protocol over the network and
cannot synchronize with devices that use other protocols or IEEE 1588 profiles or
vice versa.
-
Ensure that your system includes at least two devices that support network
synchronization. Refer to the Supported Hardware
topic for more information.
-
Ensure that the synchronization-enabled devices in your system are utilizing a
recommended connection configuration that supports network synchronization. You
can use the following topology configuration options:
-
Line topology—Also known as
daisy-chaining or bus topology. The host communicates directly with all
nodes through one bus line. A standard Ethernet device or switch can be
added to the end of the chain if desired and used as normal.
-
Ring topology—The host
communicates with all nodes through the most effective path. You must use an
external switch in a ring topology. You must configure the network properly
with a recommended external switch before creating redundant links in the
network.
-
Star topology—The host communicates
directly with each node through the external switch. Redundant links are
recommended, but optional, in this topology. You must use an external switch
in a star topology. You must configure the network properly with a
recommended external switch before creating redundant links in the network.

Note
For network
synchronization, star topology configuration requires an external IEEE
802.1AS switch. All the devices and switches on the network must be
compliant with the IEEE 802.1AS protocol for synchronization to be
enabled.
Refer to your device documentation, available at ni.com/manuals,
for additional information on synchronization and networking.
-
Ensure that synchronization is enabled by going to
File»Preferences and checking Enable
multi-chassis and network synchronization on the
General tab.
When the network synchronization-supported
devices in your system are properly connected and configured, and synchronization is
enabled in FlexLogger, the SYNC displays green in the toolbar, indicating that
synchronization is working properly. If the SYNC display is not appearing or is not
green, refer to the
Synchronization
Status topic for troubleshooting information.
