OPC Servers provide a single, consistent interface to communicate with multiple devices through the OPC standard. - OPC Servers is a software add-on for LabVIEW that converts proprietary industrial protocols to the open OPC Classic and OPC Unified Architecture (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.
