I think you're not going to have good results with web2py for this kind of project. I'd encourage you to take a look at projects as http://mblogic.sourceforge.net/ , which using python (and a bit of javascript) allows you to control, and report or easily showing animated bars and graphics. mblogic has a modular design and allows you use things as modbus, but you don't need to use modbus to build a scada-like web application. You only will need to add authentication, as mblogic (in its hmiserver module) doesn't have it implemented.
Hope this helps.
