MicroLogix 1400 Embedded Web Server
How to Use This Chapter
Rockwell Automation® offers enhanced MicroLogix™ 1400 controllers for your
EtherNet/IP control systems so you can monitor data remotely via web pages.
This chapter shows how you can use a MicroLogix 1400 controller in your
control system.
Typical Applications
With the MicroLogix 1400 controller, you can access controller and control
system data with different and remote access applications. With a web browser,
you can easily monitor live MicroLogix 1400 controller data remotely.
With the MicroLogix 1400 controller, you can access Simple web page view, and
custom-designed User Provided page views. Simple web pages use only HTML
tags and are useful in limited-communication environments where radio modems
are used.
Browser Requirements
For firmware revision 16 or later, you can access the MicroLogix 1400 controllers
only with Internet Explorer 11.0, Opera 42.0, FireFox 50.1.0, or Safari 5.1.7, or
higher.
For earlier firmware revisions, you can access the MicroLogix 1400 controllers
only with Internet Explorer 6.0, Opera 9.23, FireFox 2.0.0.14, or Safari 3.0.4, or
higher.
To access data view pages, the browser requires Javascript and XML support.
The supported display sizes start from 640 x 480. Smaller display sizes also work
but require scrolling to view the information.

Connect the MicroLogix
1400 controller to the
Network
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.

4. Access the Home page of
the web server.
In your web browser’s Address box, enter the IP address of the MicroLogix 1400
controller. The Home page is displayed.
5. Log into the web server. 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.
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 .
6. Disable the web server. 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.
Specify the IP address of the
MicroLogix 1400 controller in the
Address window of your web browser.
This is the controller’s Home page.

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.
Note: The message box for changing default passwords appear in firmware
revisions 16 and later only.
Navigate the MicroLogix
1400 Controller
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.
IMPORTANT
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.

Chapter 2
Use Data Views to Access Controller Data
How to Use This Chapter
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.
Overview of Data Views
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.

Chapter 2 Use Data Views to Access Controller Data
The available and default display formats depend on the data type of the file.
Click Back to display the previous page. To refresh the data view, click Update.
Change Data Table Files
The data in the Data File Types such as Binary, Integer, Long, Float, and String
can be changed. The Binary, Integer, and Long types support all the Display
formats. You can edit Binary types by bit, and the Octal, Decimal, and
Hexadecimal types by element. A user account with either Write or
Administrator access level can change the Data Table Files. When you click N7 in
Data Views, Data Writable appears beside a Data File Type (Integer here) as
shown below.
How to Change a Data File Type
In the steps that follow, a Binary type is assumed.
IMPORTANT
This feature is only supported in the earlier revisions of MicroLogix 1400.
It is not supported in firmware revision 21.006 or later.

1. Change Display As to Binary, then the following screen appears.
2. Double-click the data that you want to change, then the background color
turns pink.
3. Enter a value and either press Enter or click an area in the screen, then a
confirmation window appears.

4. Click OK to change the value.
The following screen appears when the value is successfully saved into the
server.
If the following screen appears, the value is not saved and the value returns
to the original value.
If you want to change the data in Decimal, click the pull-down menu to change
the Display As to Decimal and follow the steps described. The steps also apply to
the String type.
Information on String Data File Types
Take note of the following when changing String file types using the web
interface:
• The maximum string data length allowed to be saved into the controller is
82.
• Each special character translates to three characters in the network.
• When using only special characters, you can enter up to 37 characters.
• When using special characters in combination with alphanumerics, you
can enter up to 113 characters as illustrated by the formula: (alphanumeric
characters) + (special characters x 3) < 113.
