How are NI OPC Servers Licensed?



Primary Software: LabVIEW Modules>>LabVIEW DSC Module
Primary Software Version: 1.0
Primary Software Fixed Version: N/A
Secondary Software: N/A

Problem:
My NI OPC Servers shows that it is in Evaluation Mode and will expire in 2 hours; does this mean it is not activated? Also, what is the expected behavior when NI OPC Servers is licensed vs. unlicensed? Do I need a run-time license for an EXE that uses NI OPC Server?

Solution:
NI OPC Servers is individually licensed and is not part of the LabVIEW Datalogging and Supervisory Control (DSC) Module or the LabVIEW Developers Suite. 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 also installed by default with NI Lookout and NI OPC Servers(1 driver) is licensed provided that Lookout was activated using NI License Manager.

You can check the activation state of NI OPC Servers in the NI License Manager (Start»Programs»National Instruments»NI License Manager).

There is not a separate install or licensing for NI OPC Servers when it is used by a stand-alone application (EXE) versus when it is used by the LabVIEW Development environment.  The licensing for NI OPC Server is the same regardless of it is being used by an EXE or by a VI in LabVIEW, as in both instances the same NI OPC Server is being used.

The list below describes the expected behavior of NI OPC Servers depending on the version and licensing state.

NI OPC Servers - Unlicensed and Evaluation Mode
  • No change in behavior between OPC servers in evaluation and unlicensed modes
  • Sine demo driver will not timeout
  • Any other driver will timeout after 2 hours
  • Quick Client will auto shutdown after 2 hours
  • Use of OPC I/O Server in DSC is not affected by the activation state of NI OPC Servers
NI OPC Servers 2012 or later - Licensed and Activated

There are two licensing options for NI OPC Servers 2012 or later:
  • NI OPC Servers (1 driver): can connect to one driver at a time
  • NI OPC Servers (unlimited drivers): can connect to an unlimited number of drivers simultaneously
  • Quick Client will auto shutdown after 2 hours
  • Use of OPC I/O Server is DSC is not affected by activation state of NI OPC Servers
NI OPC Servers (2010 and earlier) - Licensed and Activated
  • Setups using two or less drivers will not timeout
  • Setups using more than two drivers will timeout after 2 hours
  • Quick Client will auto shutdown after 2 hours
  • Use of OPC I/O Server in DSC is not affected by the activation state of NI OPC Servers
  • When used with LabVIEW 2009 or previous, drivers appear in Demo mode in the OPC Servers about box.  This is a known issue and has been reported to R&D as Corrective Action Request (CAR) #184623.

    In NI OPC Servers, go to Help»About, then select Versions to open the Version Information Window. The screenshot below show the expected appearance for both unlicensed and licensed mode. Even though the drivers are listed as Demo, they will not timeout.

The license for NI OPC Servers is purchased separately from the LabVIEW DSC Module and LabVIEW Developer's Suite. NI OPC Servers(Unlimited drivers) license is purchased separately from Lookout. The license for NI OPC Servers is not part of SSP. 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.
 
In addition, connection to NI OPC Servers can only be made by the following clients:
  • OPC Client I/O Server (requires LabVIEW DSC Module)
  • DataSockets
  • NI Lookout
  • NI OPC Quick Client
Note: Versions of LabVIEW DSC and Lookout released prior to LabVIEW DSC 2011 SP1 and Lookout 6.6 cannot connect to NI OPC Servers 2012.
