1756-EWEB Module: Web Server and More - Rockwell Automation

Background:
The EWEB module allows the user to host web pages from the ControlLogix rack. This
enables Acme’s customers to view data from their control systems on any computer that
has an internet browser. (If the viewing computer is outside of the company network, the
user will have to bridge the firewall, similar to the process one goes through anytime he
wishes to have external access to a protected network.) The EWEB also functions as a
great place for Acme to store user documentation and help files. Acme is especially
interested in the ability to remotely access its machines in the field and potentially correct
problems without traveling to the customer site.
Technical Details the Engineers Liked:
Topics such as email servers, html, xml and asp are important to the maximum use of the
EWEB module, but beyond the scope of this class. There are plenty of good online
resources to learn about these topics, which can be found through search engines. For
example, http://www.w3schools.com/ is one good, free resource.
