I have multiple OPC server configurations that I would like to be able to select programmatically. How can I do this in LabVIEW using the LabVIEW DSC Module? NI OPC Servers A Demo version should be included with LabVIEW DSC Module or LabVIEW Real-Time Module Use Search in Windows. Search for «OPC Servers». In the distributed system manager (DSM) I can see that the local OPC1/NI OPC Client Status is Active=true, Connected=false. When I enable diagnostics.
SolutionThe method of interacting with OPC through LabVIEW varies significantly based on what version of LabVIEW you're using. You can use OPC in LabVIEW in the following ways: • LabVIEW 5.0 can communicate with OPC Servers via ActiveX Automation interface. • LabVIEW 5.1 can communicate with OPC Servers as a DataSocket Client. (Note: While this is the only OPC connection option available for LabVIEW 5.1, later versions of LabVIEW can also communicate with OPC servers via DataSocket.) • LabVIEW 6.x - 7.1 can communicate with OPC Servers through the LabVIEW Datalogging and Supervisory Control module (LabVIEW DSC replaces BridgeVIEW). The Tag Engine in DSC 6.x - 7.1 can operate both as an OPC client and as an OPC server.
• LabVIEW 8.x above can communicate with OPC Servers through the Shared Variable Engine using functionality provided by the Datalogging and Supervisory Control module. Gta 4 Asi Loader. • LabVIEW DSC 2013 - 2016 provides an API for OPC UA communication.
• LabVIEW 2017 OPC UA Toolkit can be used for OPC UA communication. Additional Information Communicate to OPC UA Server with LabVIEW DSC 2013 - 2016 or LabVIEW 2017 OPC UA Toolkit using the OPC UA API From LabVIEW 2013 to 2016, the LabVIEW DSC module contains APIs for programmatically communicating with and exchanging data between OPC UA servers and clients. Starting with LabVIEW 2017, OPC UA toolkit separates from LabVIEW DSC and becomes a stand-alone LabVIEW toolkit. See Using OPC UA Servers and Clients (DSC Module or Real-Time Module) for more information on this process. Communicate to OPC Server with LabVIEW DSC 8.0 and later using Shared Variables Starting with LabVIEW 8.0, the LabVIEW DSC module extends the functionality of the Shared Variable Engine (SVE) to allow LabVIEW to serve as an OPC DA client. OPC Server Functionality is provided by the separate NI OPC Servers software.
