Data Table Memory Map

The Data Table Memory Map page displays a list of the data table files, their type,
and size in elements for a connected MicroLogix 1400 controller. To view
memory maps, log in with a Read access group user account.

Each file contains a hyperlink that takes you to the specific Data Table Monitor
page for that file. When you click a particular file, the Data Table Monitor page

User Provided Pages

You can use a text editor to generate up to eight user-provided web pages. Each
page is stored in four consecutive ASCII files of the MicroLogix 1400 controller.
The channel configuration feature of RSLogix™ 500/RSLogix Micro (version

8.10 or later) allows you to select the starting file number and the number of user
pages to be stored, as shown in the following example:

RSLogix 500/RSLogix Micro (version 8.10 or later) also allows you to import an
HTML file from your PC to specified ASCII files in the MicroLogix 1400
controller. See page 42 for details.

HTML Pages

Rockwell Automation Publication 1766-UM002E-EN-P - June 2019 39

Referencing Other Pages/Servers - following are some basic considerations
when referencing other pages or servers:

·reference User Specified Pages in the MicroLogix 1400 controller by using
the names user1.htm through user8.htm

·to reference a page on the same controller, specify a URL such as /user2.htm

Chapter 7 User Provided Pages

·to reference a page on another processor, specify a URL such as
http://www.xxx.yyy.zzz/user2.htm, where www.xxx.yyy.zzz is the IP address
of the controller

·you can reference other WWW servers and display images from other
sources without affecting your usage of data table memory (except for the
size of the HTTP reference)

Referencing Data Table Memory - reference data table memory locations by
placing custom tags into your HTML source which specify the data table
location and optional formatting information. Use the following format for the
custom tag:

<!ABDTR-file_type{file_number}:{file_element}[,#elements][%format]>

The items surrounded by {} are sometimes optional. The items surrounded by []
are always optional.

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 (the input, output, and status
files have fixed file numbers).

When defining your custom tag, consider the following:

Tag Item Description

#elements If not specified, this defaults to one. If it is less than one, it also defaults to

%format Legal values are %d for decimal and %x for hexadecimal. The following file

Input and Output file elements are output in decimal format. Status file
elements are output in hexadecimal format with a leading 0x. Integer file
elements are output in decimal format. Complex data types (Timer, Counter,
Control, or other data types) are output as a table with bits and important
words specified.

and STring files are always output as a null terminated text string. Binary
files are always output as two binary bytes.

Generating Custom Data Table Monitor Pages

You can generate Custom Data Table Monitor pages with your text editor then
download them to the MicroLogix 1400 controller using RSLogix 500/RSLogix
Micro version 8.10 or later. The first element of the file must contain a special

tag as shown here:

<!ABCDM-xx>

where xx is the automatic refresh rate in seconds (01...99).

A value outside the range defaults to a “snapshot” display.
You can modify the refresh rate three different ways:

· enter the desired refresh rate and press the Change button

· select the Default button for a 15 second refresh

· disable the refresh by selecting the Disable button

Referencing Data Table Memory - the Data Table locations in the Custom Data
Table Monitor are referenced by placing custom tags into the ASCII file of the
processor. The format of the custom tag is:

<!ABDTR-file_type{file_number}:{file_element}[,#elements][%format]
[!comment]>

The items surrounded with {} are sometimes optional, whereas the items
surrounded by [] are always optional.

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).

When defining your custom tag, consider the following:

Tag Item Description

#elements If not specified, this defaults to one. If it is less than one, also

%format Legal values are %b for binary, %d for decimal, %0 for octal and

defaults to one. Each element is output using the same format
(whether specified with %format or defaulted). Any associated
comment is displayed only for the first element.

%x for hexadecimal. The following file types allow the format to
be specified:

· Input

· Status

· Output

All other file types are displayed in an appropriate format.

!comment Data after the exclamation point and up to the closing > is

displayed in the Comment column of the monitor.

Fixed display formats Float files are always output in floating point format (“C”%g

format). String files are always output as a null terminated text
string. Binary files are always output as four binary nibbles.
Complex data types (Timer, Counter, Control, or other data files)
are output as a table with bits and important words specified.

· Integer

Importing User Page Files to the MicroLogix 1400 Controller
