NI OPC Servers Download - A Guide for LabVIEW Users




OPC (OLE for Process Control) is a standard for data exchange in industrial automation systems. OPC enables different devices and applications to communicate with each other using a common interface, regardless of the underlying protocol or vendor. OPC has two main versions: OPC Classic and OPC Unified Architecture (UA). OPC Classic is based on Microsoft COM/DCOM technology, while OPC UA is a platform-independent, service-oriented architecture that supports more features and security options.

NI OPC Servers is a software add-on for LabVIEW that converts proprietary industrial protocols to the open OPC Classic and OPC UA protocols. This conversion to OPC enables LabVIEW applications to communicate with many different programmable logic controllers (PLCs) and third-party devices through the OPC UA Client that is included with the LabVIEW OPC UA Toolkit, providing a single platform for delivering high-performance measurements and control to industrial systems.


How to Download NI OPC Servers




To download NI OPC Servers, you need to have a valid service agreement or subscription license for this product. You can log in to your NI account to verify your eligibility and access the download page. Alternatively, you can purchase a license or update your service information to get access to the locked versions.


The download page for NI OPC Servers is available in different languages, such as English, Chinese, German, Japanese, French, and Korean. You can select your preferred language from the drop-down menu at the top right corner of the page. The download page contains information about the supported operating systems, application bitness, language, file size, checksum, release date, and previous versions of the product. You can also view the readme file for more details about the installation and usage of NI OPC Servers.


To download NI OPC Servers, you need to click on the "Download" button next to the version that you want to install. You can choose between the full version or the offline installer. The full version requires an internet connection during installation, while the offline installer allows you to install NI OPC Servers without an internet connection. After downloading the file, you need to run it and follow the instructions on the screen to complete the installation process.


How to Use NI OPC Servers with LabVIEW




To use NI OPC Servers with LabVIEW, you need to have LabVIEW installed on your computer. You also need to have the LabVIEW Datalogging and Supervisory Control (DSC) Module or the LabVIEW OPC UA Toolkit installed. The LabVIEW DSC Module includes an OPC Classic client that enables you to browse, read, and write data from OPC servers. The LabVIEW OPC UA Toolkit includes an OPC UA client that supports both OPC Classic and OPC UA servers.


To communicate with an OPC server using LabVIEW, you need to create an OPC connection in your LabVIEW project. You can do this by right-clicking on your project and selecting "New" > "OPC Connection". You can then specify the name of the connection, the type of the server (OPC Classic or OPC UA), and the address of the server. You can also configure other settings such as security mode, user credentials, timeout, and update rate.


After creating an OPC connection, you can browse the items available on the server using the "Browse Items" dialog box. You can select one or more items and drag them to your project or block diagram. You can then use the "OPC Read" and "OPC Write" VIs from the "OPC" palette to read and write data from/to the selected items. You can also use other VIs from the same palette to perform other operations such as subscribing to data changes, creating groups of items, adding or removing items from groups, and synchronizing data between groups.


Conclusion




NI OPC Servers is a useful software add-on for LabVIEW users who want to communicate with various industrial devices using the open OPC standard. By downloading and installing NI OPC Servers, you can convert proprietary protocols to OPC Classic and OPC UA protocols and access them through LabVIEW applications. This way, you can leverage the power and flexibility of LabVIEW for creating high-performance measurement and control systems for industrial applications.
