Overview of Data Views

Data views give you the ability to read from controller via a browser interface. The MicroLogix 1100 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 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.

Change an Access Group

Each data view contains a group of files that you want to monitor. Each MicroLogix 1100 controller can support multiple data views. One browser supports 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 for the given data table file, choose the access group type you wish to assign. Choose from: 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.

3. Click Apply specified.
to change an access group for the data table file you
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 1100, 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.
The available and default display formats depend on the data type of the file. Click Back to display the previous page. To refresh data, 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. The Binary can be changed by bit, and the octal, decimal, and hexadecimal can be changed 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. 1. Change Display As to Binary, then the following screen appears.
2. Double-click the data you want to change, then the background color becomes pink.
3. Enter a value and either press Enter or click somewhere in the screen, then a confirmation window appears.
4. Click OK to change the value in the server. If 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 pull-down menu to change the Display As to Decimal and follow the above procedures in sequence. The procedures are all the same for String too. (This feature is supported only when the OS FRN is 3 (HTML File Revision is 1.2) or later.

Disable Web View

Using RSLogix 500 V7.20 or higher, you can disable individual data files from being viewed via any web browser by selecting the data files 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.)

Notes:

Manage User Accounts and Access Levels
This chapter describes how to configure user access levels to different information on the module.

Topic User Accounts and Privilege Classes Configure Access Limits for Web Pages Create User Accounts Recover with Unknown Password Page 17 18
By assigning user accounts with different access levels, you can manage which users have access to view network configuration or have access to view and change data views. Several pages on the MicroLogix 1100 controller, such as diagnostics pages and data views pages, have default access protection. Before accessing these pages, you must authenticate your access by entering a user name and password. The module displays the log-in box when you access these web pages. IMPORTANT Once authenticated, you do not have to re-enter a user name or password when accessing subsequent pages. You must close your browser to log out.
The default user name is administrator with password 'ml1100' or guest with password 'guest'. IMPORTANT It is strongly recommended that you change the password for the default Administrator account.
User Accounts and Privilege Classes
The MicroLogix 1100 controller supports multiple user accounts, each with a user name and password. Each user account is configured for one of these access levels: Administrator (all access) Write (read/write access only) Read (read access only)
The access level determines which web pages the user can access. You configure access limits for individual web pages.
Configure Access Limits for Web Pages
Each page in the MicroLogix 1100 controller has one of these protection levels: Administrator Write Read The protection levels are hierarchical. Administrator users can access Read protected pages. These pre-defined pages (those web pages that come with the MicroLogix 1100 controller) in the MicroLogix 1100 controller have these default access levels. You can change the Data View access group, if needed, with administrator privilege
Web Page Home page Diagnostics pages Data Views New Data View User Management page Default Protection Level no protection Read protection Read protection Administrator protection Administrator protection

Create User Accounts

You need Administrator access to create and modify user accounts. You can create as many as 10 individual accounts. You manage accounts from the Administrative Settings User Management Edit Users page.

In this field User ID

Do this enter the user name for the account 20 characters maximum can contain these characters: A-Z, a-z, 0-9, underscore (_), and dash (-) select Administrator, Write, or Read access for the user account enter the password for the account 10 characters maximum re-enter the same password for the account
Group Password Confirm Password
If you use Internet Explorer, the number of characters allowed for a user ID or password depends on how many characters fit in the box. Larger characters (such as W) take more room and reduce the total number of allowed characters. A user account with a specific previlege can access the Data corresponding to the specific access level, i.e. a user account with Read access level can not access the Data belonging to Write or Administrator acess group. The following screen, which shows only Read Access Group, appears when you log in with the guest account.
Recover with Unknown Password
Update the firmware using ControlFlash to initialize both user accounts and the access level of data view. This feature is supported only when the OS FRN is 3 (HTML File Revision is 1.2) or later.
