Conventions Used
No special knowledge is needed to enter or edit messages. However, since
the Dataliner message display must be connected to peripheral equipment,
we assume you are familiar with communication terminology, especially
when using the Remote I/O version with a PLC.
The following conventions are used in this manual:
• All menus and screens reproduced in this manual are approximate
renderings of what you will see on your terminal screen. Allen-Bradley
reserves the right to make minor modifications to any menu or screen to
help improve performance.
• A symbol or word in brackets represents a single key that you press.
These include keys such as [A] or [Del]. Since the Dataliner can be
programmed with a variety of keyboards or terminals, the printing on
your keyboard may be different from the symbol or word indicated in
brackets. This manual uses ↵ to specify the carriage return function of a
keyboard. On your keyboard this may correspond to an [ENTER], ↵ , or
[Rtrn] key.
• The up caret, ^, may be used in place of the [CTRL] where space
requires. For example,
you should press [CTRL] and [W] keys simultaneously.
^W means the same as [CTRL][W]. This means
• In the following chapters we will refer to the Dataliner DL40 Series
Message Display as the DL40.

Introduction to the DL40
This chapter describes some of the key features and operating capabilities of
the DL40 message display. Refer to the Table of Contents or Index for help
in locating more detailed information throughout this manual.
The DL40 Dataliner Message Display is available in two- or four-line
configurations (capable of displaying 20 characters per line) in two basic
versions:
• Remote I/O. This version is designed to enable two-way communications
with the Allen-Bradley family of Programmable Logic Controllers
(PLCs) and Small Logic Controllers (SLCs). A remote I/O DL40 can
appear to the PLC or SLC as any size I/O rack (
• Parallel Port. This version is designed to receive message number
triggers, slave addresses, and variable data from a PLC or SLC output
module via 16 data lines and 4 strobe lines (indicating the type of data).
In addition, both versions support:

• RS-485 communications for serial message triggering or slave message
display network communications, or RS-485 networked message file
transfers with a PC Computer.
• RS-232 communications for direct message file upload and downloads
from a personal computer operating the DL40 Offline Programming
Software.
The DL40 stores messages of varying length within its own memory. Each
message is identified with a unique message number from 1 to 9999. The
stored messages are placed in an internal memory queue when triggered by a
command from your control system. They are then run according to
attributes you have selected in the DL40 system.
The DL40 can display a wide variety of characters and symbols, including:
• Uppercase letters
• Lowercase letters
• Punctuation
• Special characters from the extended ASCII character set
A person with normal vision can easily read the display from a distance of up
to 25 feet.

Introduction to the DL40
Onboard Editor
The onboard editor lets you create or edit messages, select message
attributes, and set options and variable formats on a Version 2.00 or later
DL40 message display using any of a number of standard keyboards.
Send ASCII Data to a PLC Via a Remote I/O Link
Using Remote I/O communications, you can send ASCII data to your PLC.
Simply attach an IBM compatible keyboard to the DL40 message display,
and you can enter parts numbers, badge numbers, and similar information as
required. The DL40 processes and displays the information, and then sends it
on to the controller.
You can enter bar code data using a wedge attached to an Allen-Bradley bar
code scanner. The DL40 displays scanned bar code information, then sends
the data to the PLC through the Remote I/O. Refer to Publications 2755-824
and 2755-824.1 for information on applications using Allen-Bradley wedges.
You can establish similar communications over an RS-485 link.
Communications with Any Programmable Controller (Parallel Port
Version)
The DL40 can accept information from any programmable controller over a
total of 20 input lines (16 data and 4 strobe lines).
Parallel Port versions of the DL40 also have a 12 VDC terminal that can be
used to power outputs that pull data and strobe lines high.
Backup Operations
You can archive DL40 applications files in a number of ways.

Introduction to the DL40
Historical Events Stack
With the DL40’s Historical Events Stack you can record the occurrence and
sequence of some or all of the messages or variable data values that have
been triggered and/or displayed. The 16K bytes of memory available for this
record will hold about 1,000 events. You can view this record on the DL40
itself, or obtain a printout for offline reference.
Clock Operations
The DL40 contains a real-time battery-backed clock that will keep accurate
time even when power is removed from the unit. The DL40 can display the
current time and/or date in either AM/PM or 24-hour military format.
Date and time information can be displayed as part of any triggered message,
and passed on to a PLC. You can also date- or time-stamp events as they are
recorded in the Historical Events Stack.
You can set the DL40 internal clock from the front panel menus, from a PLC,
or through the Offline Programming Software.
RS-232 and RS-485 Ports
The DL40 has both an RS-232 and RS-485 port.
The RS-232 port can be used to:
• upload or download message files from a computer
• print messages and/or Historical Event Stack contents
• upload or download message files using a data (tape) recorder
The RS-485 port can be used to:
• trigger messages with or without variable data content
• multi-drop upload or download message files from a personal computer
• send messages to slave message displays
• input ASCII data via keyboard or wedge
Debug Mode (Parallel Port Version)
2–6
The DL40 allows you to display the binary status (1 or 0 value) of both the
strobe and data lines to check the output of a programmable controller.
Chapter 2
Introduction to the DL40
Auxiliary Devices
You can connect a variety of useful auxiliary devices to the DL40 message
display as needed to meet your own unique needs.
• Slave displays. You can address up to 126 DL10 or DL50 slave displays
over an RS-485 network at distances up to 2,500 feet (762 m) from the
originating DL40. You can also control the annunciation relay on remote
DL50 Series slave displays. By assigning a specific address to each slave
display, you can control which slaves receive and display a given
message.
• Printers. A serial printer allows you obtain a hard copy of the Historical
Events Stack or a listing of the internal application file itself. The time
and date that a message was triggered can be included on the stack
printout if you so desire. You can also set message attributes so that
triggered messages will be sent via RS-232 immediately to the printer.
• Alarms. The alarm relay permits an external remote alarm or warning
light to be activated and deactivated. Individual message attributes can be
set to energize or de-energize the alarm relay contacts
ATTENTION: The DL40 alarm relay should be used for
annunciation purposes only. It may not be used for control
!
applications.
Background Messages
You can specify a background message that will be displayed whenever the
DL40 has no other triggered messages in the queue to run.
Hidden Messages
You can also create hidden messages which will not appear on the DL40
display or have any affect on what is being displayed, but can be sent to a
slave display, printed, or stored on the Historical Events Stack.
Embedded Variables
The messages you create on the DL40 can contain variable data in response
to changing data input. Incoming variable data can be binary, BCD (binary
coded decimal), and/or ASCII. You can also embed time and date
information in a message from the DL40’s internal battery-backed real-time
clock.
2–7
Chapter 2
Introduction to the DL40
Data Mode Selection
When using the DL40 message display, you can select from two data modes
• binary
• Binary Coded Decimal (BCD) either signed or unsigned
Within any application, triggers and variable data can be in either form. For
example, message triggers can be in a binary format, while variable data can
be BCD.
Message Chaining
The DL40 allows you to create a chain of messages for display in sequence.
Only the first event in the chain need be triggered from outside. Then each
message in the chain can trigger the next until the complete sequence has
run.
Adjustable Parameters for Serial Communications
With the DL40 you can configure RS-232 or RS-485 port parameters as
needed for compatibility with printers, data recorders, slave displays, or
control computers. Configurable parameters include:
• Baud Rate. Available baud rates include:
300 4800
1200 9600
2400 19200
• Parity. You can transmit data with:
Odd parity
Even parity
No parity
• Handshake. You can choose from:
Software
Hardware
None
• Data Bits per Character. Either 7 or 8
• Null Count. From 0 to 255. This setting allows you to send a string of
nulls to the printer between characters. It is useful with slower printers
that drop characters because they can’t keep up with normal DL40 output.
• Page Width. Between 20 and 132 characters
