  • OPC Servers

Issue Details

  • My NI OPC Servers shows that it is in Evaluation Mode and will expire in 2 hours; does this mean it is not activated?
  • 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?
  • Do I need an annual subscription to use this product?
  • I have a serial number for NI OPC Server.  NI OPC Server 2010 doesn't activate, but NI OPC Server 2016 activates.  Is the serial number version specific?
  • I have a serial number for OPC UA, will that activate NI OPC Server?

Solution

Software that Installs and Activates NI OPC Servers

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 also installed by default with NI Lookout. When NI Lookout is activated using NI License Manager, NI OPC Servers(1 driver version) is also licensed through the same activation.

NI LabVIEW OPC UA Toolkit is a separate product and will not activate NI OPC Server. 


NI OPC Servers Licensing and Activation

  • NI OPC Servers(Unlimited drivers) license is purchased separately from Lookout.
  • 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). 
   

OPC Servers in EXE vs LabVIEW Development

The licensing for NI OPC Servers is the same regardless if it is used by a stand-alone application (EXE) or by a VI in LabVIEW, as in both instances the same NI OPC Server is being used.  There is no run-time OPC Server.
 

Expected Behavior of NI OPC Servers

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
*Note: The 2 hours refer to the time that has elapsed since the OPC Servers' service started.

 
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 in 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.
 

Additional Information

In addition, connection to NI OPC Servers can only be made by the following clients:
  • OPC Client I/O Server (requires LabVIEW DSC Module)
  • LabVIEW 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.
