FX-30S Modbus setup

What is the typical workflow to get an FX-30S setup to communicate to an industrial machine over Modbus RS485? Is this something that requires custom coding and configuration in the FX-30S or is there a way to create machine profiles over a graphical user interface or AirVantage for example where a few simple Modbus registers can be named & entered and then downloaded or pushed to the FX-30S?

We are just trying to get a rough idea of how much engineering time & resources is involved to get one of these gateways set up and ready to go because we have about half a dozen different industrial machines (frequency converters for example) that we want to pull data from.
