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?
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
There are two licensing options for NI OPC Servers 2012 or later:
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.
