The Shared Variable Engine (SVE) uses the NI Publish-Subscribe Protocol (NI-PSP) to enable the data transfer of shared or network variables through a network. The SVE manages the use and connectivity of shared or network variables on single or multiple systems.

Stopping Shared Variable Engine

Select Actions»Stop Local Shared Variable Engine to shut down the SVE. You can create, configure, and remove variables in the System Manager after you shut down the SVE. While the SVE is shut down, variable values do not update, and the SVE does not log alarms for variables.

Starting Shared Variable Engine

Select Actions»Start Local Shared Variable Engine to restart the SVE. The SVE is always running after you install LabVIEW, LabWindows/CVI, or Measurement Studio unless you select Actions»Stop Local Shared Variable Engine to manually shut down the SVE.
