Important User Information
Solid state equipment has operational characteristics differing from those of electromechanical equipment. Safety Guidelines for the Application, Installation and Maintenance of Solid State Controls (Publication SGI-1.1 available from your local Rockwell Automation sales office or online at http://www.ab.com/manuals/gi) 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.
The examples and diagrams in this manual are included solely for illustrative purposes. Because of the many variables and requirements associated with any particular installation, Rockwell Automation, Inc. cannot assume responsibility or liability for actual use based on the examples and diagrams.
No patent liability is assumed by Rockwell Automation, Inc. with respect to use of information, circuits, equipment, or software described in this manual.
Reproduction of the contents of this manual, in whole or in part, without written permission of Rockwell Automation, Inc. is prohibited.

EtherNet/IP Web Server Module 3

Environment and Enclosure

This equipment is intended for use in a Pollution Degree 2 industrial environment, in overvoltage Category II applications (as defined in IEC publication 60664-1), at altitudes up to 2000 meters without derating.
This equipment is considered Group 1, Class A industrial equipment according to IEC/CISPR Publication 11. Without appropriate precautions, there may be potential difficulties ensuring electromagnetic compatibility in other environments due to conducted as well as radiated disturbance.
This equipment is supplied as "open type" equipment. It must be mounted within an enclosure that is suitably designed for those specific environmental conditions that will be present and appropriately designed to prevent personal injury resulting from accessibility to live parts. The interior of the enclosure must be accessible only by the use of a tool. Subsequent sections of this publication may contain additional information regarding specific enclosure type ratings that are required to comply with certain product safety certifications.
NOTE: See NEMA Standards publication 250 and IEC publication 60529, as applicable, for explanations of the degrees of protection provided by different types of enclosure. Also, see the appropriate sections in this publication, as well as the Allen-Bradley publication 1770-4.1 ("Industrial Automation Wiring and Grounding Guidelines"), for additional installation requirements pertaining to this equipment.

WARNING
Publication
When you insert or remove the module while backplane power is on, an electrical arc can occur. This could cause an explosion in hazardous location installations. Be sure that power is removed or the area is nonhazardous before proceeding. Repeated electrical arcing causes excessive wear to contacts on both the module and its mating connector. Worn contacts may create electrical resistance that can affect module operation.

EtherNet/IP Web Server Module 17
Obtain an IP Address
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 of the EtherNet/IP Web Server Module User Manual,
publication ENET-UM527 to assign an IP address to the web server module.
Access the Home Page of the Module

Log Into the Module
Many of the features of the web server module require you to log in with appropriate access. If you select a feature, such as New Data View, the web server module prompts you to enter your user name and password. The default user name is “Administrator” with no password (leave the Password field blank).
Default Access:
User Name: Administrator (not case sensitive)
Password:
(leave blank, no password)
You can set up as many as 25 user accounts. Each account can have read, read and write, or administrator access. For more information, see the EtherNet/IP Web Server Module User Manual, publication ENET-UM527.

20 EtherNet/IP Web Server Module
Create a Data View
Before you can create a data view in the web server, the tags you want to view must exist in the controller that is local (in the same chassis) to the web server module. The tags in the controller must be controller-scoped. For example, create:
TEST type DINT controller-scope
value 123
To create a create a data view, you need Administrator or Write access. You
create a data view from the Data Views New Data View page.
1. In the Create Data View window, specify a name for the data view and enter a description (optional).
2. In the New Data View window, specify at least one tag (EWEB_test in this example). You must specify the:
slot number of the controller
tag name (exactly as it is in the controller)
type of tag
how to display the tag data
access limit of the data view
