You can use shared variables to share data among VIs in a project or across a network. Time-triggered shared variables transfer data across a closed private network, or time-triggered network, deterministically. Other RT targets on the time-triggered network then can access the data.

Complete the following steps to deterministically share data across a network using time-triggered shared variables.

1. Configuring the RT targets for time-triggered communication.
2. Create a time-triggered shared variable under the RT target.
3. Connect using a crossover cable, network hub, or non-blocking Ethernet switch the secondary Ethernet cards of all the RT targets to create a closed private network.
4. Configure the closed private network for time-triggered communication.

After you create the time-triggered network, you can create a timing source for the time-triggered network that you can use to control timed structures.
