Modbus to labview
Connecting a RS485 communicating device to LabVIEW software

Modbus Library for Labview

I made a labview project using ICP's temp datalogger. First of all you need to download ni's modbus library. They gave me a vi that can directly read Modbus registers. I made some changes on the block diagram to make it look nice. It is pretty easy, pm me if you need help.
