Hi Everybody
Thanks for all your replies so far, I did think of setting up some software in the controller to send information back, but sometime when we goto different sites they don't want us to mess around with the program. I know there are programs like Netscan but what would look really good is to have a page I can open and drop onto the desktop which will show just boxes for each controller, red could mean offline and green could mean online just something simple like that if possibe.
