#Ni opc server example install
Local OPC Systemsįor a local OPC system, you install both the OPC server and the OPC client on the same computer running Windows.Īs shown in the following illustration, a plant contains an industrial network of control devices that communicates with the OPC server using an industrial protocol such as serial or ENET. Refer to the OPC Foundation Web site for more information about the OPC specifications. Version 3.0-Variable Engine OPC Server, (DSC Module) DSC OPC Client.x-DataSocket Client, Variable Engine OPC Server, (DSC Module) DSC OPC Client. LabVIEW currently supports the following versions of the OPC DA Specification: The OPC Foundation has released three major versions of the OPC specification. You can use the OPC UA VIs to create OPC UA server or OPC UA client applications. Note The LabVIEW Datalogging and Supervisory Control Module and the LabVIEW Real-Time Module also support the OPC UA specification. You also can develop OPC clients in LabVIEW to connect to other OPC servers. You can connect to the LabVIEW OPC server from third-party OPC clients. Note LabVIEW supports the OPC Data Access specification. The OPC Foundation currently maintains eight OPC specifications: These specifications also help you control processes and collect data in the plant and then transfer and use that data enterprise-wide.
#Ni opc server example code
The OPC Foundation developed the OPC specifications so you can use devices from more than one manufacturer and interchange devices throughout a plant without having to change the code that communicates with those devices. The OPC Foundation-comprised of representatives from manufacturers of control systems, instrumentation systems, and process control systems-oversees the development and maintenance of the OPC specifications. OLE for Process Control (OPC) is a set of standard interfaces developed to ensure interoperability among control devices from different manufacturers for the transfer of real-time plant data.
