2. Connect the module to
the network.

Connect the MicroLogix 1400 controller to the Ethernet network. The RJ-45
connector is on the left-hand side of the module.

3. Obtain an IP address.

By default, the MicroLogix 1400 controller is BOOTP enabled. If you connect
the MicroLogix 1400 controller to a network that has a BOOTP server, that
server will assign an IP address to the MicroLogix 1400 controller and the LCD
screen of the MicroLogix 1400 controller will display BOOTP IP address.

If your network does not have a BOOTP server, use one of the methods
described in the MicroLogix 1400 Programmable Controllers User Manual

1766-UM001

to assign an IP address to the MicroLogix 1400 controller.

MicroLogix 1400 Embedded Web Server Chapter 1

Specify the IP address of the
MicroLogix 1400 controller in the
Address window of your web browser.

This is the controller’s Home page.

Default Access

User Name: administrator or guest
(case sensitive)

Password:
(ml1400 for administrator, guest for guest)

4. Access the Home page of
the web server.

5. Log into the web server.

In your web browser’s Address box, enter the IP address of the MicroLogix 1400
controller. The Home page is displayed.

Many of the features of the MicroLogix 1400 controller require you to log in with
appropriate access. If you select a feature, such as Data Views, the MicroLogix
1400 controller prompts you to enter your user name and password. The user
name is either administrator or guest. The password is ml1400 for administrator
and guest for guest.

6. Disable the web server.

Rockwell Automation Publication 1766-UM002E-EN-P - June 2019 9

Note: This login screen appears in firmware revisions 16 and later only.

You can set up as many as 10 user accounts. Each account can have read, write, or
administrator access. For more information, see User Management .

We recommend disabling the Web Server if it is not required for the application.
For more information, see Knowledgebase article 732398 - How to disable the

web server in MicroLogix 1100 and 1400.

Note: You will need to log in using your TechConnect? Account User Name and
Password.

IMPORTANT

Security Warning

To enhance web server security, upon logging in to the MicroLogix 1400 Web
Server page with the default administrator account and default password, a dialog
box displays to notify the user to change the default password.

Navigate the MicroLogix 1400 Controller

For firmware revision 21.006 or later, if you log into the
web server as an administrator or guest for the first time, a
message box prompts you to change the default password.
You cannot proceed to the next step without changing the
default password.

Note: The message box for changing default passwords appear in firmware
revisions 16 and later only.

You navigate the web server’s web pages by using the navigation panel on the left
of the screen. There are also tabs across the top you can click to navigate the
folders containing documents.

Overview of Data Views

The MicroLogix™ 1400 controller provides access to the controller data table files.
This chapter shows you how to set up views of data table files.

Change Data Table Files

Disable Web View

Data views give you the ability to read controller data via a browser interface. The

MicroLogix 1400 controller provides web pages that let you configure a set of files

(a data view) that can be read.

A data view consists of an HTML file and an XML file with data file
information. The HTML file is in a readable ASCII format. It contains the File
Name, File Type, # of Element, and Access Group.

Chapter 2 Use Data Views to Access Controller Data

Change an Access Group

Each data view contains a group of files that you want to monitor. Each
MicroLogix 1400 controller can support multiple data views. One browser
supports only one data view, so if you want to look at many data views, you need
to run a corresponding number of browsers.

You change an access group from the Data Views → New Data View page.

1. From the Access Group pull-down menu of the given data table file, choose
one of the following access group types:

· Administrator (all access except write)

· Write (read/write access only)

(1)

· Read (read only)

2. Choose Administrator, Write, or Read from the Access Group pull-down
menu to change a file's access group.

3. Click Apply to change an access group for the data table file
you specified.

(1)

For MicroLogix 1400, revision 21.006 or later, Write access is not supported and is listed as Invalid from the
drop-down selection.

Monitor Data Views and Data Table File

Use the Data Views → Data Views page to view existing data table files.
Click the file name to view the data within a data table file.

Data View Page

The Data Views page displays a list of the data table files, their type, and size in
elements for a connected MicroLogix 1400, as shown in the following example.

Each file contains a hyperlink that takes you to the specific Data Views page for
that file. When you click a particular file, the Data Views page appears, displaying
the contents of the data table file you selected.
