Here are some sites that will help.

ControlNet International: http://www.controlnet.org/
Devicenet (ODVA): http://www.odva.org
Ethernet/IP specification is available from either of the above sites. This is the Ethernet protocol AB uses in their products.

Swapnil, re-email Phil a request to send the updates you missed. I am sure he will send them to you. I missed the first two and emailed a request and received the missing updates.

thanks Robert,
