NI LabVIEW Full Development System and LabVIEW DSC With these features, LabVIEW becomes apowerful HMI/SCADA package for industrial control applications. This module includes tools for logging data toa networked historical database, real-time and historical trending, managing alarms and events, networking LabVIEW Real-Timetargets and OPC devices into one complete system, and adding security to user interfaces. The LabVIEW Datalogging and Supervisory Control (DSC) Module is used in this tutorial.

In this tutorial, learn how to use LabVIEW tocommunicate with a networked PLC using OPC. OPCServers are available for virtually all PLCs and programmable automation controllers (PACs). OLE for Process Control (OPC)defines the standard for communicating real-time plant data between control devices and human machine interfaces (HMIs). NI LabVIEW software can communicate with any programmable logic controller (PLC) in a variety of ways. This article is part of a series outlining the capabilities of the LabVIEW Data logging and Supervisory Control(DSC) module.Ĭlick here to view the list of other articles. 02/04/13 Connect LabVIEW to Any PLC Using OPC - Developer Zone - National Instruments
