Topic Overview of Data Views Page 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.
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 → New Data View page. 1.
Use Data Views to Access Controller Data Monitor Data Views and Data Table File 9 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.
10 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.
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.
12 Use Data Views to Access Controller Data 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.

User Provided Pages 35 HTML Examples - the following example shows an HTML code segment with a short description of what you would see on a web browser: Examples Generating Custom Data Table Monitor Pages HTML Code Web Browser Displays Input image word I:0 the value of the first word of the input image table in the default format of decimal with bold type Timer T4:0 the values of the timer in T4:0 in the default format of a table Timer T4:0 the values
36 User Provided Pages You must always specify the basic file reference. Depending on which file is being referenced, file_number or file_element may be defaulted. If the file_type is I, O or S, the file_number does not need to be specified, but the file_element must be specified. If the file_type is not one of the three special files, the file_number must be specified and the file_element may default to zero (because the input, output and status files have fixed numbers).
User Provided Pages 37 7. Repeat this process for each user page file. 8. When all user page files have been imported, go online with your MicroLogix 1400 controller processor. 9. Select the User Provided Pages link to view the User Provided Pages menu, as shown in the following example: Click on the User Provided Page #X to display that specific page.
