Most often people use the Modbus driver to connect to the M340.

You'll need to know the relevant Modbus addresses to get anything useful out of it.

I have successfully moved Booleans and Integers by following the Ignition Manual directions. Being that said I have not been able to move Float. I am using a REAL variable in M340, HRF and Float in Ignition. Any Suggestions?

Try the "Reverse Word Order" setting on the driver.
