Using an OPC UA Server (OPC UA Toolkit).Creating an OPC UA Server with OPC UA Toolkit.More information about LabVIEW OPC UA Toolkit (National instruments) You will find them here:Ĭ:\Program Files.\National Instruments\LabVIEW 20xx\vi.lib\OPCUA\client\internal\ Note that Multiple Write.vi and Multiple Read.vi are slightly more complicated to use.īut if you open previous code in LabVIEW 2017 or newer, it will still work, because the old Write.vi and Read.vi are still included, but hidden in the palette in LabVIEW. This means: In LabVIEW 2017 and newer it is recommended to use Multiple Write.vi and Multiple Read.vi instead of Write.vi and Read.vi for new applications. Note! When creating OPC Clients: The VIs Write.vi and Read.vi that was previously used in LabVIEW 2016 has been replaced with Multiple Write.vi and Multiple Read.vi. The LabVIEW DSC Module and the LabVIEW Real-Time Module no longer contain the OPC UA API. From the 2017 release, the LabVIEW OPC UA Toolkit becomes a standalone product. The LabVIEW OPC UA Toolkit contains the OPC UA API that was formerly part of the LabVIEW Datalogging and Supervisory Control (DSC) Module and the LabVIEW Real-Time Module.
