Do some digging on NI's website for the LabView code.

Here's the Modbus library:

LabView Modbus Libary 1.21

Be sure to read the user comments about a bug in one of the vi's.

Here's NI's Modbus introduction:

Assuming the V230's will be slaves, all you have to do on the Unitronics side is configure the Ethernet port, trigger a Modbus IP configuration block with SB 2, and hang a Modbus IP ScanEX block on the rail.
