Licensing SystemLink Products

Last Modified: June 29, 2020

Determine which licensing options to choose based on your SystemLink products and goals.

NI Volume License Manager (VLM) handles licenses for SystemLink. The computer on which you install VLM becomes a license server.
SystemLink requires three license types:
  • Server
  • Module Node
  • Module User
  1. Install Volume License Manager. Use the following table to determine which installation option fits your needs.
    Number of SystemLink Servers Installation Option Description
    1 Install VLM on the same computer as SystemLink Server
    • Reduces network complexity
    • Ensures SystemLink Server and VLM can always communicate
    Install VLM on a remote computer, separate from SystemLink Server
    • Allows you to use an existing license server
    • Requires connectivity between both machines
    Multiple Install VLM with each SystemLink Server installation
    • Reduces network complexity
    • Specifies node seat quantity for each server

    This option may require multiple license agreements.

    Install VLM on one license server for multiple SystemLink Server installations
    • Connects multiple SystemLink Servers and nodes to a single license server
    • Enables transferring licenses among servers
  2. Determine how many VLM installations you will need and how many server, user, and node licenses you will need. The following table shows common setup scenarios and the licensing requirements for each.

    Use module node licenses for each SystemLink module. Examples of modules include the Software Configuration Module, Asset Module, and Test Module.
