Now lets start with communicating PLC and LabView through Kepware OPC server. LabView and PLC communication through OPC Server In this tutorial we are using Kepware OPC server for communication.īelow is the picture of DataSocket palette in LabView which shows you different buttons for performing different task as explained below.ĭataSocket Display URL: Displays a dialog box for the user to select a data source and returns the URL to that data.ĭataSocket Open: Opens a data connection you specify in URL.ĭataSocket Read: De queues the next available data value from the client-side buffer associated with the connection you specify in connection in and returns the data.ĭataSocket Write: Writes data to the connection you specify in connection in.ĭataSocket Close: Closes a data connection you specify in connection id. Let me tell you that we can use LabVIEW as an OPC client by connecting to an OPC server through a DataSocket connection and we done same and communicated OPC server and LabView through DataSocket VI. In this tutorial we will guide you how you can communicate LabView and PLC through an OPC server.
In Automation industry we use different-different devices and software to implement or projects and OPC server ( OLE for Process Control) is one such very useful software or protocol which is widely used. LabView has found its use in many places and many of the engineers are making their design on LabView.
As we all know that LabView is a software which is used for designing and development environment for a visual programming language and is from National Instruments.
