Sharing Data Using Network Variables

You can use network variables to share data between applications across a network.

Network Variable Engine

When you create a network variable on a target, the Network Variable Engine on the target hosts the network variable. The Network Variable Engine sends the data you share to other targets across the network.

When an RT target hosts a network variable, that target controls the data and other targets do not affect the availability of the network variable. If availability is not a concern, consider hosting the network variable on the host computer. This frees up processor time on the target and allows you to use the security features.
