Labview is software, and Modbus is a commumications protocol.  What hardware do you have?  What means are you using to communicate?  232? 485? Ethernet?

I want to use RS485 to connect between my PC and the PLC.

thanks you

You haven't said which PLC you have, and since PCs don't typically have 485 ports, you will more than like have to make up your own cable.  Get a pinout for the PLC and for whatever 232 to 485 converter you are going to use.  B&B Electronics has app notes for both Modbus and 422/485 here: http://www.bb-elec.com/tech_articles/rs422_485_app_note/table_of_contents.asp
