.

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
1400 controller.

to assign an IP address to the MicroLogix

3. Access the Home page of
the web server.

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

This is the controller’s Home page.

4. 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.

Default Access

User Name: administrator or guest
(case sensitive)

Password:
(ml1400 for administrator, guest for guest)

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 on page 23.

How to Use This Chapter

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.

Overview of Data Views 7
Change an Access Group 8
Monitor Data Views and Data Table File 9
Change Data Table Files 10
Disable Web View 12

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.

7 Publication 1766-UM002A-EN-P - November 2008

8 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 → N e w D a t a V i e w p a g e .

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)

• Write (read/write access only)

• Read (read access only)

2. Choose Administrator, Write, or Read from the Access Group

pull-down menu to change a file's access group.

Publication 1766-UM002A-EN-P - November 2008

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

you specified.

Use Data Views to Access Controller Data 9

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.

Publication 1766-UM002A-EN-P - November 2008

10 Use Data Views to Access Controller Data

Change Data Table Files

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.

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.

Publication 1766-UM002A-EN-P - November 2008

How to Change a Data File Type

In the steps that follow, a Binary type is assumed.

Use Data Views to Access Controller Data 11

1. Change Display As to Binary, then the following screen appears.

2. Double-click the data 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.

Disable Web View

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.

Using RSLogix 500/RSLogix Micro V8.10 or higher, you can disable
individual data files from being viewed via any web browser by
selecting the data file’s properties page and checking the Web View
Disable checkbox as shown below. Any data file property changes
must be made offline and downloaded to the processor or later.
