Modbus addresses

[Graham]

Hello,
I'm working on a .Net Netduino application that grabs data from my Classic 200 to display a web status page that can be viewed on a smart phone or tablet. http://netduinosolar.codeplex.com
Is there an updated modbus address document?
I'm looking for the correct address for Total AMP Hours, Amp hours daily and days since last float (4128, 4125, 4140).
Also, does anyone have documentation or sample code on how to extract log data from the classic?

thanks
Graham.
