Hello Shridhar,

Connecting to a PLC over Modbus requires a few setup steps in LabVIEW to ensure you can connect to or create a Modbus server.  Have you looked through our documentation about connecting to PLC's with modbus?  I have linked it below to give you some information on doing this with a generic PLC.  There are further links to learn more at the bottom of the document should you need more information.  Please take a look through these documents and let me know if you have any further questions!
