NI LabVIEW software can communicate with any programmable logic controller (PLC) in a variety of ways. OLE for Process Control (OPC) defines the standard for communicating real-time plant data between control devices and human machine interfaces (HMIs). OPC Servers are available for virtually all PLCs and programmable automation controllers (PACs). In this tutorial, learn how to use LabVIEW to communicate with a networked PLC using OPC.
