http://literature.rockwellautomation.com
) describes some important
differences between solid state equipment and hard-wired electromechanical
devices. Because of this difference, and also because of the wide variety of
uses for solid state equipment, all persons responsible for applying this
equipment must satisfy themselves that each intended application of this
equipment is acceptable.
In no event will Rockwell Automation, Inc. be responsible or liable for
indirect or consequential damages resulting from the use or application of
this equipment.

About the Enhanced Web Server Module
13 Publication ENET-UM527E-EN-P - October 2006
Both the 1756-EWEB and 1768-EWEB modules, known as Enhanced
Web Server modules, provide access to information from the control
system using a web browser.
Using an EWEB module, you can monitor and modify control system
data remotely using XML web pages.
14 Getting Started
Enhanced Web Server Module Applications
The following features and applications are available with your
Enhanced Web Server Module.
• Remote access to controller data using a standard web browser
Use a standard web browser to monitor live controller data in
two ways: use data views that you create in the web server
module, or custom-develop your own web pages.
For example, create a custom web page for managers to monitor
production processes directly from their desks. Use data views
or custom web pages for OEMs to remotely monitor controller
data and reduce support costs.
• Deliver data initiated by the control system
System data and information can be sent via email when
initiated by a controller in the system. The controller uses a
message instruction to initiate an email. Use the email to notify a
maintenance person or an engineer of an alarm or alert so that
corrective actions can be done in a timely fashion.
The system can also send system status or production reports.
The module supports all email clients, such as email applications
and text pagers.
• Share system data with external applications
The module stores data in its data views in XML files. This
generic XML data presentation allows external applications to
easily access and manipulate system data.
XML support is also platform and operating system neutral, so
you can share data between different applications. For example,
design a database application to obtain controller data from the
web server module to streamline the data acquisition process.
In addition, the module supports an open-socket interface that
lets a Logix controller communicate with Ethernet devices that
do not support the EtherNet/IP application protocol, such as bar
code scanners or RFID readers.

Features of EtherNet/IP Web Server Module in a Control System
The module provides the following features and services in the
control system.
• Bridging and routing of messages
Like other EtherNet/IP modules, you can route messages,
upload/download programs, and flash upgrade modules using
the web server module as part of the communication path to
access the target device.
• Data access (read and write) to controllers
Access the XML pages in the Enhanced Web Server module to
view and modify data that resides in a controller that is in the
same chassis as the EWEB module.
• Custom web pages
Create custom web pages that are tailored to your application.
Use ASP functions to populate your web pages with live
controller data.
• Email capability
You can initiate email messages from the embedded email
composer in the module. You can also use the module to send
an email initiated by a Logix controller via a MSG instruction.
• Open-socket interface
You can open TCP or UDP communication links to other
standard Ethernet devices via the module.

monitor and modify data in the controllers using a computer with
standard Web browser software.

1756-EWEB Installation
To install a ControlLogix Enhanced Web Server Module (1756-EWEB),
follow these steps.
1. Align the module with a slot in the 1756 chassis.
2. Slide the module back into the chassis until it snaps into place.
3. Connect the module to the network.
The RJ-45 connector is on the bottom, front of the module.

RJ-45 EtherNet/IP
Connector
Connect the cable here.
4. Obtain an IP address.
For more information, see chapter 2.
By default, the web server module is DHCP enabled. If you
connect the web server module to a network that has a DHCP
server, that server will assign a dynamic IP address to the web
server module and the four-digit display on the front of the web
server module will display each of the four numbers of the IP
address.
If your network does not have a DHCP server, use one of the
methods described in chapter 2 to assign an IP address to the
web server module.
Publication ENET-UM527E-EN-P - October 2006
18 Getting Started
1768-EWEB Installation
To install a CompactLogix Enhanced web Server module, complete
the following steps.
1. Open the DIN rail latches on the module.
2. Align and press the module onto the DIN rail to the left of the
controller.
3. Slide module snugly against the controller.
Publication ENET-UM527E-EN-P - October 2006
4. Install a power supply and other modules.
5. Close all the DIN rail latches.
6. Obtain an IP address.
