NI OPC Server Licensing


NI OPC Servers is individually licensed and is not part of the LabVIEW Datalogging and Supervisory Control (DSC) Module or NI Software Suites. When you install the DSC Module, NI OPC Servers is installed by default with a temporary license for a two-hour evaluation period.

NI OPC Servers is available for download online or on NI Package Manager.

NoteNI LabVIEW OPC UA Toolkit is a separate product, and its serial number does not activate NI OPC Servers. 


NI OPC Servers Licensing and Activation

  • If your system's PLCs fall into multiple categories on this page, you will need to purchase a license for NI OPC Servers (Unlimited drivers). To purchase a license, contact NI Sales.
  • The license for NI OPC Servers is not part of SSP, and does not require an annual subscription to operate.
  • NI OPC Servers 2012 and later use a different licensing scheme than previous versions of the NI OPC Servers. Because of that, you cannot use your NI OPC Servers 2012 and later serial number to activate an earlier version of NI OPC Servers or vice versa. If you are wanting to migrate to OPC Server 2012 or later, you will need to acquire a new license.
  • You can check the activation state of NI OPC Servers in NI License Manager (Start>>Programs>>National Instruments>>NI License Manager). 
  • If you wish to upgrade your license, you will need to buy each upgrade separately. 

Note: there is no run-time version of NI OPC Servers. While some of NI's products have a trimmed-down license available for deployment systems, every system that runs this software must have its own full license.
