Using this Manual
Intended Audience
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.
Conventions Used
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 [Delete]. 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 [Return] key.
• The up caret, ^, may be used in place of the [CTRL] where space
requires. For example, ^W means the same as [CTRL][W]. This
means you should press [CTRL] and [W] keys simultaneously.
• DL40 Plus refers to the Dataliner DL40 Plus Message Display

The DL40 Plus is available in a 2- or 4-line configuration (capable of
displaying 20 characters per line) with either Remote I/O or Parallel
port communication options.
Remote I/O Version
The Remote I/O version enables two-way communications with the
Allen-Bradley family of PLCs and SLCs. A remote I/O version of
the DL40 Plus can appear to the PLC or SLC as any size I/O rack
(1/4, 1/2, 3/4, or full).
Parallel Port Version
The Parallel Port version receives 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).

Overview of the DL40 Plus
RS-485/RS-232 Communications
Both the Remote I/O and Parallel Port versions have RS-485 and
RS-232 ports. You can configure these ports for Programmer, DL
Slave or Open Protocol communications (see table below). Port
settings are modified through the Ports menu in the Offline
Programming software or the Onboard Editor. You select a
communication option under the Port Use submenu.
The RS-232 port always communicates with the Offline
Programming Software regardless of the configured mode. Open
Protocol or DL Slave operation can occur on either the RS-232 or
RS-485 port.
If the RS-485 port is configured for Open protocol, you cannot
configure the RS-232 port for the same protocol. Instead, an
information message reports an invalid port configuration.

The DL40 Plus stores messages of varying length. Each message is
identified by a unique message number from 1 to 9999. Messages
are placed in an internal memory queue when triggered by a
command from your control system. They are then run according to
attributes selected in the DL40 Plus.
The DL40 Plus can display a wide variety of characters and symbols,
including:
• Uppercase letters
• Lowercase letters
• Punctuation
• Special characters from the extended ASCII character set
• English character set (default)
• International character set ISO 8859–1
• Cyrillic character set (Russian)
Note: English characters are also available with both the
International an Cyrillic character sets.

Onboard Editor
With the Onboard Editor you can create or edit messages, select
message attributes, and set options and variable formats using a
standard IBM PC keyboard. The Keyboard port is located on the rear
panel of the DL40 Plus.
Send ASCII Data to a PLC via Remote I/O Link
Using Remote I/O communications, you can send ASCII data to a
PLC. Attach an IBM compatible keyboard to the DL40 Plus and you
can enter part numbers, badge numbers, passwords, and similar
information as required. The DL40 Plus processes and displays the
information, and then sends it to the controller.
You can establish similar communications over an RS-232 or
RS-485 link.
Communicate with any Programmable Controller
(Parallel Port Version)
The DL40 Plus accepts information from any programmable
controller over a total of 20 input lines (16 data and 4 strobe lines).
Parallel Port versions of the DL40 Plus have an isolated 12 VDC
supply output that can be used to power outputs that pull data and
strobe lines high.
Backup Operations
Archive DL40 Plus application files in the Offline Programming
Software (Catalog No. 2706-LSW) by uploading or downloading
files between a computer and DL40 Plus displays.
Publication 2706-6.1

Overview of the DL40 Plus
Historical Events Stack
The Historical Events Stack records the occurrence and sequence of
some or all messages and logs variable data values that have been
triggered and/or displayed. The 16K bytes of stack memory holds
about 1,000 events. You can view information in chronological order
or by frequency of occurrence, or print the record.
Clock Operations
A real-time battery-backed clock keeps accurate time even when
power is removed from the unit. The DL40 Plus can display the
current time and/or date in either AM/PM or 24-hour military
format.
Note: The date function is year 2000 compliant.
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.
Set the DL40 Plus internal clock using the front panel menus, a
keyboard connected to the Onboard Editor, a PLC, or the Offline
Programming Software.
RS-232 and RS-485 Ports
The DL40 Plus has both an RS-232 and RS-485 port.
Use the RS-232 port to:
• upload or download message files from a computer
• trigger messages via Open protocol (ASCII triggering)
• send messages to a single slave message display
• print messages and/or the contents of the Historical Event Stack
Use the RS-485 port to:
• multi-drop upload or download message files from a computer
• trigger messages via Open protocol (ASCII triggering)
• send messages to one or more slave message displays
• input ASCII data via bar code
Publication 2706-6.1
Overview of the DL40 Plus
1–9
Keyboard Port
Use the Keyboard port on the DL40 Plus to:
• edit options, messages, communication port settings
• input ASCII data to a host controller, PLC, or computer
• trigger messages using Open protocol (ASCII triggering)
Debug Mode (Parallel Port Version)
Use Debug mode to display the binary status (1 or 0 value) of the
data lines and the state of the strobe lines. This mode is useful for
checking the output of a programmable controller.
Auxiliary Devices
Connect a variety of useful auxiliary devices to the DL40 Plus
display.
Slave Displays
Address up to 126 DL40 Plus or DL50 slave displays over an
RS-485 network at distances up to 4,000 feet (1200 m) from the
originating DL40 Plus. You can also control the annunciation relay
on remote DL40 Plus or 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
Connect a serial printer to print the Historical Events Stack or a
listing of the internal application file. The time and date a message
was triggered can be included on the stack printout. You can also set
message attributes such as sending triggered messages to a printer
through the RS-232 port.
Alarms
The alarm relay activates or deactivates an external remote alarm or
warning light. Individual message attributes can be set to energize or
de-energize the alarm relay contacts on DL40 Plus or slave displays.
!
ATTENTION: Use the DL40 Plus alarm relay for
annunciation purposes only. Do not use the alarm relay
for control applications.
Publication 2706-6.1
1–10
Overview of the DL40 Plus
Background Messages
Specify a background message that will display whenever the DL40
Plus has no other triggered messages in the queue.
Hidden Messages
Hidden messages do not appear on the DL40 Plus display or have
any affect on what is being displayed. Hidden messages can be sent
to a slave display, printed, or stored on the Historical Events Stack.
Embedded Variables
Messages can contain variable data. Variable values are received
when the message is triggered. 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 battery-backed
real-time clock of the DL40 Plus.
Data Mode Selection
When using the DL40 Plus with Remote I/O or parallel input for
communication, you can select 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.
Note: When using serial RS-232 or RS-485 communications, all
data is in ASCII character format.
Message Chaining
Chain messages together for display in sequence. Only the first
message in the chain is triggered from the host controller. Then each
message in the chain can trigger the next until the complete sequence
has run.

Change Formatted Variable [CTRL][F]
Use [CTRL][F] to change the formatting parameters of a variable. To
do so, place the cursor under the symbol for the variable you want to
change, then press [CTRL][F]. You are prompted to modify one or
more of the 3 formatting parameters described below:
Parameter
Acceptable values

0 to 6 (the maximum value is one less than the
variable size selected above)
Suppress Zeroes
(appearing in front of the
first significant digit)
Y(es) or N(o)
Insert ASCII or BCD Variable [CTRL][W]
You can send a single word ASCII or BCD variable to insert in a
message. Use [CTRL][W] to specify the insertion position. The
software will insert the symbol for an ASCII or BCD variable (↕).
BCD data consists of 4 digits per word and ASCII data consists of 2
characters per word.
Variables can be strung together to form compound variables up to
20 ASCII or 40 BCD characters in any combination, not to exceed
10 words.

Insert Request for ASCII Input Data [CTRL][X]
A data request requires you to enter ASCII Data (8-bit ASCII
character) through the Keyboard port into the displayed message.
• When returning ASCII Input Data via RS-485/RS-232 Port, the
message requesting the data must be triggered via the RS-485
port. This is true for both Parallel Port and Remote I/O units.
Data is automatically entered when you press [↵ ].
• With Remote I/O units, the ASCII input data is sent via Remote
I/O port to the PLC as part of the Return Message Number
displayed. Data can be returned to your PLC in:
– Message/Variable/Slave Run mode
– Message/Variable Run mode
– Message List Run mode
User requested data is sent to the PLC as part of the I/O scan. Up
to 20 ASCII characters can be sent with Block Transfer. Up to 12
ASCII characters can be sent with Discrete Transfer (depending
on rack size).
The Enter bit is set only after all ASCII data requested has been
inserted in the message. Data is not considered valid until the
Enter bit is set.
Important: If more ASCII data is requested than can be
returned to the PLC, the excess data is lost.
To enter a data request, place the cursor just after the point where
you want to insert the request. Use [CTRL][X] to specify the insertion
position. The software will insert the symbol for a single byte data
request (↑).
Insert Time Into a Message [CTRL][T]
To enter the time in a message, place the cursor just after the point
where you want the time inserted. Use [CTRL][T] to specify the
insertion position. The software will insert the symbol for a time
variable (HH:MM:SS).
The time variable occupies 8 of the available 20 characters on a
display line.
You can use the time variable in any Run mode.
Publication 2706-6.1
Using the Onboard Editor to Create Messages
2–9
Insert Date Into a Message [CTRL][Y]
To enter the date in a message, place the cursor after the point where
you want the date to appear, then press [CTRL][Y]. The software will
insert the date symbol DAY MON DT (the numerical day of the
month). You can use the date variable only once in a given message.
The date variable occupies 10 of the available 20 characters on a
display line.
Note: We recommend setting message attributes such as Display
Line and Scroll Message before typing in the message. This allows
you to verify the placement of characters as you type them.
Testing Messages
Press [CTRL][R] while editing a message to run the message as it
would be displayed in Run mode except:
• Message is not put on Historical Events Stack
• [CTRL][V] and [CTRL][W] variable data is not displayed in a
message. They are represented by asterisks (****)
• [CTRL][X] Data Requests are represented by underscores (_ _ _).
Values for Data Requests can be put into a message for testing
using a keyboard
• Data not returned via Remote I/O or RS-485/RS-232 port
Message Attributes
Message attributes apply to all messages when they are created. You
can modify the message attributes for an individual message by
using [CTRL][A] while editing the message. Message attributes you
can control from the Onboard Editor are:
• Display Line
• Scroll message
• Print message
• Send to Slave (Address 0 - 127)
• Wait Time
• AutoClear
• AutoRepeat
• Chain to Msg
• Energize relay
• Stack Message
• Send message time to the stack
• Hide message
• Acknowledge message
• Slave color
• Slave length
• Echo relay

Scroll Message
This message attribute determines whether the message will scroll
across the DL40 Plus display. You can activate scrolling only if the
Display Line attribute has been set to a single line. Type [Y][↵] to
activate or [N][↵] to deactivate.
Print Message
If the Print message attribute is set to Y, then the DL40 Plus will
send any triggered message to a printer via the RS-232 port. The
message is printed only once (even if the Auto repeat attribute is
active) unless the message variable data changes. If new variable
data is received while the message is running, then the message will
be printed more than once. Type [Y][↵] to activate or [N][↵] to
deactivate.
You must configure the RS-232 port for Programmer use.
Publication 2706-6.1
Using the Onboard Editor to Create Messages
2–11
Send to Slave
If you enter a slave address number, the message is sent to the slave
each time it is triggered. However, in Message/Variable/Slave mode,
a slave address sent with the message trigger overrides this attribute.
Important: To send any message to a slave, Port Use for the
RS-232 or RS-485 port must be set to DL Slave.
If the AutoRepeat attribute is active, the message is sent to the slave
each time it repeats. If the message has embedded variables, it is sent
to the slave each time new variable values are received during the
message wait time. Possible values for this field include:
Entry:
Which means:
0
Don’t send to slave
1 through 126
Send to the single identified slave address
127
Send to all slaves
Invalid slave numbers are 4, 6, 7, 13, 18, 20, 22, 43, 45, 48–57. The
DL40 Plus will not accept any of these numbers.
Wait Time
This setting means one of two things to the DL40 Plus display.
• If you activated Scroll message, the value here represents the
scrolling rate in tenths of a second. For example, a value of 8
results in the display of the next new character in a message every
0.8 seconds.
• If Scroll message is not active, then the value here represents the
number of seconds a message appears on the message display.
For example, a value of 5 assures that the message will appear on
screen for 5 seconds whenever it runs.
Acceptable values for this field can range from 0 through 31.
Publication 2706-6.1
2–12
Using the Onboard Editor to Create Messages
AutoClear
Activating this attribute tells the DL40 Plus to clear the message
from the display after the Wait Time for the message has expired,
even if no other messages are triggered.
This value applies only to the lines used by a single message. For
example, if this message uses line 2 only, then line 2 is cleared. Lines
1, 3 and 4 remain unchanged.
Important: AutoClear de-energizes the alarm relay only if the
message cleared had energized the relay. A DL40 Plus
slave or DL50 slave message display must always be
sent a message that de-energizes the relay.
Type [Y][↵] to activate or [N][↵] to deactivate.
AutoRepeat
This attribute causes the display to repeat a message continually until
another message is available in the queue to run. AutoRepeat only
functions if the DL40 Plus is operating in Message/Variable/Slave or
Message/Variable Run mode.
This attribute is useful when you need to update variables repeatedly
within a message.
Type [Y][↵] to activate or [N][↵] to deactivate.
Chain to Message
This attribute lets you link two messages together so that the second
message runs automatically after the Wait Time has expired. The
second message requires no additional triggering and no special
modification of its attributes to respond. Also, the link is independent
of the second message, which means that the second message can
also run independently under other circumstances.
The second message has its own attributes, which may be different
from those of the first message. There is no limit to the number of
messages that can be chained together, and messages can be chained
to Special Messages.
Note: If AutoRepeat is active, the Chain to Message attribute is
disabled
Activate this attribute by entering a valid message number.
Publication 2706-6.1
Using the Onboard Editor to Create Messages
2–13
Energize Relay
Activating this attribute displays the message and energizes the
display’s alarm relay whenever the message is triggered.
The alarm relay will not de-energize even after the Wait Time has
expired. The relay will de-energize when:
• a message is run for which the Energize relay attribute is not
activated
• any Special Message runs
• the display exits Run mode
Important: AutoClear de-energizes the alarm relay only if the
cleared message has the Energize relay enabled.
!
ATTENTION: Use the relay for annunciator purposes
only. Do not use it for control.
Type [Y][↵ ] to activate or [N][↵ ] to deactivate.
Stack Message
This attribute records the message number and trigger time of the
message on the Historical Events Stack. Variables are also placed on
the stack. Stacked messages can also be stamped with the time the
message was run (as opposed to the trigger time stamp).
If AutoRepeat is enabled, the message number (and time) is put on
the Historical Events Stack only once each time the message is
triggered and/or run rather than each time it repeats. The message
number, variables, and time (if applicable) are put on the Historical
Events Stack while the message is running or repeating only when
updates to variables are received by the DL40 Plus.
Type [Y][↵ ] to activate or [N][↵ ] to deactivate.
Stack Time
This attribute records the time and date the message was run on the
Historical Events Stack. By default, only the time and date when the
message was triggered is recorded.
Type [Y][↵ ] to activate or [N][↵ ] to deactivate.
Publication 2706-6.1
2–14
Using the Onboard Editor to Create Messages
Hide Message
This attribute suppresses the message from displaying on the DL40
Plus but does send it to a slave display, printer, or place it on the
Historical Events Stack. The other attribute settings for the message
determine its destination(s).
For example, assume the Hide message, Print message and Send to
Slave 2 attributes are enabled. The message will not appear on the
display but a copy of the message is printed and displayed on the
slave addressed as 2.
Note: When used with [CTRL][X] (ASCII Input Data), the underscore
prompt for this data is still displayed on the DL40 Plus even when
the Hide Message attribute is active.
Type [Y][↵ ] to activate or [N][↵ ] to deactivate.
Acknowledge Message
This attribute holds the message until you press the [MSG ACK] button on
the front of the DL40 Plus. The next message is displayed only after
the [MSG ACK] button is pushed.
Note: We recommend that you enable message queueing when using
this attribute.
Type [Y][↵ ] to activate or [N][↵ ] to deactivate.
Slave Message Color
This attribute lets you control the color of a message sent to a
color–capable slave display such as the DL50 Tri–Color Marquee
Display. You can select from three different colors on a per message
basis: red, amber, or green.
Slave Message Length
Use this attribute only with the DL50 slave displays. Its purpose is
to display 10 character messages on “short” DL50 displays (Catalog
No. 2706–F11J, –F11JC) operating in large text mode. Large text
mode displays characters that are 4.8 in. (12.2 cm) tall.

Using the Onboard Editor to Create Messages
2–15
Slave Message Echo Relay
This attribute sends the energize relay command to the DL40 Plus or
DL50 slave addressed in the Send message to slave number attribute.
These commands are sent in addition to any specified message text.
After this attribute sends a relay command to the slave, the slave
relay will not de–energize until another message is sent to the slave
that meets both of the following conditions:
• Energize relay is set to No ( to de–energize the relay)
• Echo relay to slave is set to Yes (to send a de–energize command
to the slave display)
Notes on Using Message Attributes
• If the default attributes are changed, changes apply only to
messages created after that change.
• To change the message attributes of a single existing message,
use the [CTRL][A] editing function.
• Characters from the Extended ASCII, international, and Cyrillic
character sets can only be entered via the Offline Programming
Software. See Appendix D, ASCII Character Sets, for character
set symbols and how to enter these characters in messages.

Type [Y][↵ ] to activate or [N][↵ ] to deactivate.
Autorun Message Number
The autorun message is a message that displays when your DL40
Plus is powered up or anytime run mode is entered. It can be any
message including a message in the Message List.
Specify a message number (a value of 0 deactivates the autorun
message).
Note: If Remote I/O communications between a DL40 Plus and a
PLC are not established at power-up, the autorun message runs only
if switch 8 on Switch Bank #2 (Last State) is ON.
Background Message Number
The background message runs for a minimum of 2 seconds after the
last triggered message has finished its display wait time. The
background message is displayed until a valid message is triggered
or until Run mode is exited. The background message does not
support variable data.
Specify a message number (a value of 0 deactivates Background
Message).
Note: If Remote I/O communications between a DL40 Plus and PLC

Offline Operating Modes
Putting Messages on the Stack
• Requires the Message Attribute to be set using the Onboard
Editor or Offline Programming Software for each message you
want on the stack.
• Messages are put on the stack with variables and ASCII Input
included.
• Variables in a message are put on the stack as soon as they are
received by the DL40 Plus. An additional stack entry for a
message is made if:
– an updated variable is received for a variable already on the
stack and more than 2 seconds elapse between receiving the
original variable and the updated variable.
– if less than 2 seconds elapse, the original variable put on the
stack will be overwritten by the updated variable.
• Messages can be be put on the stack with time & date stamping.
• Messages are put on the Historical Events Stack each time they
are triggered.
Note: Bit Trigger Run Mode Only – The Bit Trigger Table is put
on the stack as soon as it is received by the DL40 Plus. Each time a
message with the stack attribute set is displayed or redisplayed, an
entry for that message is put on the stack.
Time and Date Stamping of Messages Put on the Stack
• Requires the Message Attribute to be set using the Onboard
Editor or Offline Programming Software for each message you
wish to stamp.
• The real time clock value is added to message data on the stack
when:
– a message is run
– a message is triggered (if it is never run)
– a message is triggered and if the time between triggering and
running is more than 1 minute
– if an additional stack entry is made because variable data is
updated (see above)
– a message is acknowledged

Serial Port Communications
Using the RS-232 Port
You can use the RS-232 port to:
• upload or download message files up to 50 feet (15.24 meters)
using a direct or point-to-point connection.
See the Dataliner DL40 Plus Message Display Offline
Programming Software User Manual (Publication 2706-6.2) for
details.
• communicate to a single slave message display.
Note: To send messages to a slave, you must set the Port Use for
the RS–232 port to DL Slaves.
• trigger Open protocol messages.
• input variable data in the Message Variable/Slave Run Mode and
Message Variable Run Modes using open protocol triggering.
• dynamically add or delete messages to or from the list in Message
list run mode.
• print Historical Events Stack.
• print messages as they are triggered for display (if the Print
Message attribute is set).
• print user application file (parameters and messages).
• test displaying messages.
• set the DL40 Plus using your computer’s real time clock.
• return [CTRL][X] (ASCII Input) data.
Note: ASCII Input Data can only be returned via the RS–232 Port if
the message was triggered via the RS–232 Port.
Publication 2706-6.1
Serial Port Communications
Using the RS-485 Port
6–3
You can use the RS-485 port to:
• upload and download message files using a multi-drop
connection.
• communicate to one or more slave message displays.
Note: To send messages to a slave, you must set the Port Use for
the RS-485 port to DL Slaves.
• trigger Open protocol messages.
• input variable data in the Message/Variable/Slave Run mode and
Message/ Variable Run modes using Open Protocol triggering.
• dynamically add or delete messages to or from the list in Message
List Run mode.
• test displaying messages.
• set the DL40 Plus using the computer’s real time clock.
• return [CTRL][X] (ASCII Input) data.
Note: ASCII Input data can only be returned via the RS-485 Port if
the message was triggered via the RS-485 Port.
!
ATTENTION: Do not attempt to trigger messages and
return ASCII Input Data simultaneously. Doing so will
cause both transmissions to become corrupted.

Triggering Messages
using Open Protocol
6–5
This section describes how to use Open protocol to trigger messages
in each of the Run modes. Open protocol is formatted differently for
each Run mode.
The Open protocol format for triggering serial ASCII messages is
identical for the RS-232, RS-485 and Keyboard ports.
Activating Open Protocol
The Keyboard port is always active for Open protocol
communications. You can configure the RS-232 or RS-485 port for
Open protocol using one of these options:
• Onboard Editor [CTRL] [R]
• Front Panel push buttons [SELECT] [↵ ]
• Offline Programming software
Message/Variable/Slave Run Mode
In Message/Variable/Slave Run mode, messages are triggered using
the following formats:

Run mode is the normal operating mode for the DL40 Plus. In Run
mode, messages are triggered to display on the DL40 Plus and
optionally on slave message displays.
The Parallel port version of the DL40 Plus enters Run mode after a
reset except when the Run Mode/Debug DIP switch is set to Debug.
When using the Parallel port for communications, two Run modes
are available:
• Message/Variable/Slave triggers a message with 0 to 40
variables depending on the trigger method and the variable type.
You can send messages to slave displays specified as a message
attribute or optionally override the slave address attribute for each
trigger occurrence.
• Message List triggers a message list with a maximum of 20
messages in round robin order. Permits slave message displays
specified as a message attribute.
You can select the type of run mode you want using the Onboard
Editor or Offline Programming Software. The table on the next page
provides an overview of the differences between the two Run modes.

Parallel Port Communications
Selecting Binary or BCD Data
The Parallel port uses either the Binary or Binary Coded Decimal
(BCD) numbering system to transfer message numbers and
[CTRL][V] (formatted) variables. It uses BCD or ASCII for
[CTRL][W] (unformatted) variables. Select a data format using the
Onboard Editor or the Offline Programming Software.
The numbering system you use is usually based on the format used
by your controller. With binary numbers you can input variable data
in the range of –32,768 to +32,767 (2’s complement binary). With
BCD numbers, the variable data can range from –9,999 to +9,999.
Using Binary Data Input
A data line may either be at ground level or have a voltage present.
A voltage representing a value of 1 and ground representing a value
of 0, is known as High True Logic. The opposite is Low True Logic.
You can set the DL40 Plus to accept High True or Low True Logic
using the Onboard Editor or the Offline Programming Software.
The table below shows the binary value of each data line.

Logic Voltage Levels
Each parallel input interprets two voltage levels: ON or OFF. There
is also a third state which should be avoided, an indeterminate state.
The indeterminate state occurs when the voltage is between the ON
voltage range and the OFF voltage range.
The table below lists the voltage levels and their logic values.
Voltage Range
0 – 0.8 VDC
0.8 – 3.5 VDC
3.5 – 24 VDC
High True Logic

Indeterminate
1 (ON)
Low True Logic
1 (ON)
Indeterminate
0 (OFF)
You can select either the High True or Low True Logic using the
Onboard Editor or the Offline Programming software.
To ensure proper data, the GND terminal must be connected as a
voltage reference point.
Note: You can use 120 volt AC/60 Hz input voltages if two Catalog
Number 2706-NG2 Input Converters are used.
The parallel port is compatible with Allen-Bradley’s DC Output
Modules as outlined in the table below. Two 2706-NG2 AC input
converters are required with the AC Output Module. The 12 VDC
output connection can be used to power the DC connections of the
2706–NG2 AC input converters.

You can trigger messages using the:
• Parallel port
• Keyboard port
• RS-485 port
Send Variables to be included in a Message
Your controller can include variables with the message trigger. Up to
10 full word variables can be sent with the message trigger. Variable
types include:
• 16 bit binary (1 variable per word)
• 8 bit ASCII (2 per word)
• 4 digit signed Binary Coded Decimal (BCD) (1 per word)
• 1 digit (4 bit) unsigned BCD (4 per word)
You can send variables over an RS-232/RS-485 link or using the
Keyboard port of the DL40 Plus. See Chapter 6, Serial Port
Communications, for details.
Insert ASCII Data in a Message
Use the DL40 Plus Keyboard port to input ASCII data for display.
• Insert ASCII data in a message by inserting [CTRL][X].
• Up to 20 ASCII characters can be requested for each message

• ASCII data can be strung together to form inputs with a
maximum of 20 ASCII characters.
• While a message is running, enter the ASCII character or string
of ASCII characters followed by a [↵ ].
See Chapter 6, Serial Port Communications, for details.
Return ASCII Data to a PLC
A maximum of 20 ASCII characters are returned via the RS-485 port
or the RS–232 port.
Put Messages on Historical Events Stack
Triggered messages and variable data can be put on the 16 Kbyte
Historical Events Stack. The contents of the stack can be viewed on
the DL40 Plus display or printed:
• in chronological order
• by number of occurrences
Publication 2706-6.1

Parallel Port Communications
Override Slave Address Selected as a Message Attribute
The Message/Variable/Slave Run mode allows runtime override of
the slave address specified in the “Send to Slave” message attribute.
To send a message to a slave, Port Use of the RS-485 or RS–232 Port
must be set to DL Slaves.
Triggering Rules
•
•
•
•
Optional slave address must always precede the message number.
Up to 10 variables are addressable within a message.
Variables must always follow the message number.
Variables are always associated with the last message triggered:
– if the message is in the queue, variables are put into the queue
(with the message) and onto the Historical Events Stack.
– if the message is running and the variable is displayed, the
variable is updated with the latest data and the data is put onto
the Historical Events Stack.
– if the message is running and the variable is no longer shown
(as in a scrolling message), new data is not shown but is put
on the Historical Events Stack.
– if the message is finished running, new data is lost to the
display and to the Historical Events Stack.
• BCD Sign Bit – Only valid for [CTRL][V] BCD variables; not
valid for [CTRL][W] BCD.

The number you assign to a variable by setting strobe lines does not
necessarily correspond to the position of the variable in a message.
The DL40 Plus expects to see all [CTRL][V] variables numbered
before [CTRL][W] variables.
Triggering Rules Example
If a message has variables positioned as follows:
[CTRL][V]
[CTRL][W]
[CTRL][V]
[CTRL][W]
[CTRL][V]
First
Position
Second
Position
Third
Position
Fourth
Position
Fifth
Position
they must be numbered:
[CTRL][V] first position = Variable 1
[CTRL][V] third position = Variable 2
[CTRL][V] fifth position = Variable 3
[CTRL][W] Second and fourth position = Variable 4
Note: [CTRL][V] variables always use a (16 bit) word;
[CTRL][W] variables do not use a full (16 bit) word.
If the variables are not numbered as shown, they would be displayed
in wrong positions and possibly corrupted.
• If [CTRL][W] variables are ASCII (8 bit) variables, [CTRL][W]
second position would be sent in the high byte of Variable 4;
fourth position would be sent in the low byte of Variable 4.
Publication 2706-6.1
7–10
Parallel Port Communications
• If [CTRL][W]s are BCD (4 bit) variables, the [CTRL][W] in the
second position would be sent in the high nibble (4 bits) of the
high byte of Variable 4; the [CTRL][W] in the second position
would be sent in the low nibble of the high byte of Variable 4.
The low byte of the Variable 4 would be ignored (unless the
message contained more BCD variables).
Message List Run Mode
This section shows operations you can perform in Message List Run
mode.
Create a List of Messages for Continuous Display
The list is created by adding message numbers to the list while the
DL40 Plus is in Run mode. See Chapter 6, Serial Port
Communications, for details on adding (or deleting) messages using
the RS-485/RS-232 port or the keyboard port.
• Messages are displayed in the order they are put on the list.
• Messages can be added to or deleted from the list while the list is
running.
• Messages are added to the end of the list. If a message is deleted
and re-added to the list, it is re-added to the end of the list.
• You can send a Priority Message Number which is queued as in
the Message/Variable/ Slave Run mode. When the message that is
currently displayed finishes running, all Priority Messages in the
queue will be run. After queued messages complete running, the
DL40 Plus resumes running the Message List.
Unlike the Message/Variable/Slave Run Mode, you cannot send
variables to be included in a message.
Important:
The Message List is lost if you leave Run mode, reset
the DL40 Plus, or cycle power. You will have to create
a new list when you re–enter Run mode.
Put Messages on the Historical Events Stack
Same as Message/Variable/Slave Run Mode but includes entries for
adding or deleting messages.
Note: If the message’s Historical Events Stack attribute is set,
message data will be put on the stack once for each time the message
is displayed or redisplayed.
Publication 2706-6.1
Parallel Port Communications
7–11
Send Message to Slave Address Selected as a Message Attribute
To send a message to a slave, Port Use of the RS-485 or RS–232 port
must be set to DL Slaves.
If the message’s Print attribute is set, the message will be printed
once for each time it is displayed or redisplayed. Set the Port Use for
the RS–232 port to Printer.
In the Message List Run Mode, messages are continually being
displayed by the DL40 Plus. Messages can be added to or deleted
from the message list while the list is running. In addition, Priority
Message Numbers can be sent to override the message list.
In Message List Run mode, the 4 strobe lines specify an instruction
to be performed.

Parallel Port Communications
Sampling
While the DL40 Plus is in Run or Debug mode, it regularly monitors
the 20 lines on the parallel port. Input data is only considered valid
when all lines remain unchanged for the time specified by Data Hold
Time in the Triggering Port Setup.
You must insure that any data sent to the DL40 Plus is held stable for
at least as long as the Data Hold Time. If there are any switching
delays on the lines, data must be held for the length of the Data Hold
Time plus delay time.
Since the DL40 Plus has a feature which prevents a message number
or variable from being entered more than once, there is no problem
holding data for longer periods of time. When a DL40 Plus reads the
data at the parallel port, a copy of the data is retained. If the next
reading during the sample interval is the same, the DL40 Plus will
ignore the second sampling, preventing the same data from being
sent to the queue more than once per scan. If you want to re–trigger a
message or variable, MS0–MS3 lines should be set to a minimum of
10 msec (plus switching delay time).
AC Sampling
To input AC into the Parallel Port, two AC to DC Converters
(Catalog Number 2706–NG2) must be used. When using a converter,
Using AC/DC Converter in the Triggering Port Setup must be set to
Yes. This will prevent Data Hold Time from being set to less than 40
msec. Conversion time must be added to the Data Hold Time.

Remote I/O Communications
Overview of Remote I/O
Communications
Run mode is the normal operating mode for the DL40 Plus. In run
mode, messages are triggered for display on the DL40 Plus and (if
desired) on slave message displays.
The Remote I/O version of the DL40 Plus always comes up in run
mode after a reset.
The Remote I/O DL40 Plus has four run modes:
• Message/Variable/Slave Mode triggers a message with 1 to 40
variables (depending on rack size, trigger method, and variable
type). In this mode, you can override the slave address message
attribute.
• Message/Variable Mode is similar to the Message/Variable/Slave
mode except you cannot override the slave address message
attribute.
• Message List Mode triggers a message list with a maximum of
20 messages in round robin order.
• Bit Trigger Mode triggers a priority message and a maximum of
496 messages in priority and/or round robin order.
Select a run mode using the Onboard Editor or the Offline
Programming Software. The table on the following page provides an
overview of the differences between run mode types.
Important: A message completes running when one of the
following occurs:
• Wait Time expires
• message is acknowledged
• message completes printing
• message is sent to slave(s)
• handshaking is complete
• all ASCII Input Data is entered
Note: When using a Remote I/O DL40 Plus for serial ASCII (open
protocol) communications, the “NO PLC COMMUNICATION”
error message may be disabled by setting DIP switch S2, position 10,
to ON.

Remote I/O Terminology
The following terms are used in this chapter:
Acknowledge Bit
Set by the DL40 Plus whenever the MSG ACK Push Button (on the
front panel) is pressed after the message has run and the
Acknowledge Attribute for the message is set. An operator has
physically acknowledged a message triggered by the PLC.
Add/Delete Bit (only for Message List Run Mode)
Bit Set = adds Message Number (in word 1) to Message List.
Bit Clear = deletes Message Number (in word 1) from Message List.
ASCII Character
One byte characters entered using the Keyboard Port. These are only
valid for messages that have ASCII Input Data [CTRL][X] callouts.
BCD Sign Bit
Only valid for [CTRL][V] BCD variables; not for [CTRL][W] BCD.
Bit Set
=
-
Bit Clear
=
+
Note: For BCD variables only. This bit is ignored for binary
and ASCII variables. For negative binary variables, use a 2’s
complement.
Clock/Date Data Bit
Set by the DL40 Plus to indicate that clock data
(hour-minute-second) or date data (month-day-year) is being
returned to the PLC. You request clock or date data by triggering
Special Message 912 (or 12) or 913 (or 13), or by setting the Always
Send Clock file attribute. This bit is not set for a returning message
number to a PLC.
Diagnostic Code
Bit 10 Set
= Display is not in the Run Mode
Bit 10 Clear
= Display is in the Run Mode
Bit 11 Set
= Message buffer (queue) is not full
Bit 11 Clear
= Message buffer (queue) is full
Bit 12
= Reserved
Bit 13 Set
= Display not operating properly
Bit 13 Clear
= Display operating properly
Enter Bit
Set after all ASCII input data a message requires has been entered
into a message. It is only after this bit is set that ASCII input data
should be considered valid.
Publication 2706-6.1
Remote I/O Communications
8–5
Handshake Bit
Tells the sender (either the DL40 Plus or the PLC) that the Image
Table (either Output or Input) was received. Handshaking is selected
by setting the Handshake DIP switch on the back of the unit. See
page 8–16 for a description of handshaking.
Hour-Minute-Second/Month-Day-Year

DL40 Plus displays communicate with PLC controllers and Remote
I/O scanners and sub-scanners as if they were a Remote I/O rack.
The DL40 Plus is compatible with all Allen-Bradley scanners that
support Remote I/O. The DL40 contains all the necessary
electronics to connect directly to the Remote I/O cable linked to a
PLC, scanner, or sub-scanner.
A sub-scanner may be used with any PLC 5/15. It allows the PLC
5/15 to communicate with up to 7 logical racks and a maximum of
16 devices, or chassis, as they are commonly called. Scanners have
both physical and logical specifications:
Physical Specifications - The maximum number of separate Remote
I/O devices (such as I/O racks, drive systems, DL40s) the scanner
can communicate with.
Logical Specifications - The maximum number of racks the scanner
can address.
Note: Different scanners have different physical and logical
specifications. See the next page.
To configure the DL40 Plus with PLC controllers you need to know:
• appropriate PLC or scanner module
• amount of I/O the DL40 Plus uses for different applications
• number of chassis (1771 I/O racks or DL40s) and the amount of
rack I/O addressing the scanner can accommodate
For Example
A typical valid Remote I/O configuration for PLC 5/15 would be:
(4) 1/4 racks, (2) 1/2 racks and (1) full rack
Total devices = 4 + 2 + 1 = 7 devices.
This configuration is within the physical specification of
12 for the PLC 5/15.
Note: PLC 5/15 Series B, Revision H or later have partial rack
addressing. Earlier versions were limited to full racks.
4 x 1/4 racks
2 x 1/2 racks

3 logical racks
This is within the 3-rack logical limitation of the PLC 5/15. An
invalid Remote I/O configuration for a PLC 5/15 would be (8) 1/2
racks. Although 8 is less than the 12 device physical specification,
(8) x 1/2 = 4 logical racks which is greater than the PLC 5/15’s 3
rack logical specification.

Remote I/O Communications
The table below lists the number of separate chassis or devices the
scanner can support and how much I/O it can address.
Note: For any application, the total of all the I/O used by each device
(I/O rack, drive system, or DL40 Plus) connected to the cable gives
the number of full racks of I/O being supported by the scanner or
sub-scanner for that application.

Remote I/O Communications
Triggering Messages
8–13
With the Remote I/O version of the DL40 Plus, messages are
normally triggered from a PLC connected to the DL40 Plus.
However, messages can also be triggered via the Keyboard port, the
RS-485 port or the RS-232 port.
DIP Switch 2-4 enables or disables Block Transfers.
• Discrete I/O (Block Transfers disabled)
– Block Transfers are ignored
– amount of data sent/returned depends on rack size
• Block Transfer enabled
– data in Discrete I/O image tables ignored
– amount of data sent/returned independent of rack size
Triggering the Same Message Consecutively
To avoid retriggering of a message via the I/O scan, the DL40 Plus
looks for changes to the message number in the Output Image or
Block Transfer Write to trigger messages. To trigger the same
message twice in a row, you must:
• trigger the message the first time.
• trigger a message with a Message Number of 0.
• trigger the original message a second time.
Note: In Message/Variable/Slave run mode, changing the slave
address also retriggers the same message.
Publication 2706-6.1
8–14
Remote I/O Communications
Returning Data to the PLC
The DL40 Plus returns two types of data to a PLC:
• ASCII Input data
• Clock/Date data
ASCII Input Data
The DL40 Plus returns ASCII Input data during the PLCs I/O scan as
part of the Input Image Table or Block Transfer Read Data Table.
This happens automatically unless you request that Clock/Date data
be returned. You can only input ASCII Input Data using the
Keyboard port. This data is cleared after one scan or read.
Clock/Date Data
Two ways to request that the DL40 Plus return Clock/Date data are:
• Set Always Send Clock Data to yes.
Note: Always Send Clock Data is a parameter of the Triggering
Port Setup for Remote I/O.
• Trigger special message 912 or 12 (time) or 913 or 13 (date).
The PLC must internally keep track of which special message was
triggered to determine if time or date data is being returned.
The DL40 Plus continues to return Time/Date data as a response to
special message 912 or 913:
• for 100 milliseconds if Hardware handshaking is not set
or
• until the DL40 Plus receives acknowledgement that the PLC has
received the data if Hardware handshaking is set.
Whenever Clock/Date data is being returned to the PLC, the
Clock/Date data bit in the Input Image Table is set.
Publication 2706-6.1
Remote I/O Communications
Sending Variables
8–15
When variables are sent, all [CTRL][V] (formatted) variables must be
sent first followed by [CTRL][W] (unformatted) variables.
Note: ^W means the same as [CTRL][W].
Example:
If a message has variables positioned as follows:
[CTRL][V]
[CTRL][W]
[CTRL][V]
[CTRL][W]
[CTRL][V]
First
Position
Second
Position
Third
Position
Fourth
Position
Fifth
Position
and [CTRL][W] variables are ASCII, they would be sent in the
following order:
WORD n
^V 1st position
WORD n +1
^V 3rd position
^V 5th position
WORD n +2
^W 2nd position
WORD n +3
^W 4th position
MSB
LSB
If [CTRL][W] variables are BCD variables, word n+3 would look
like:
WORD n +3
^W 2nd position ^W 4th position
MSB
UNUSED
LSB
Publication 2706-6.1
8–16
Remote I/O Communications
Handshake Bit
The Handshake Bit tells the sender (either the DL40 Plus or the
PLC) that the Image Table (either Output or Input) was received.
For complex system configurations, there may not be enough time to
insure that data is received by the PLC. You can use the Handshake
feature to make sure that data is not lost. When activated, the
Handshake feature holds data until the DL40 Plus receives
acknowledgment from the PLC that it has received the data.
The Handshake feature uses an input and output bit in the PLCs I/O
Image Tables. The DL40 Plus will automatically toggle the input
Handshake Bit to its opposite state (0 to 1 or 1 to 0).
To select the Handshake feature, enable (set ON) Switch 7 of DIP
Switch Bank # 2.
Consider using the Handshake feature when:
• large number of Remote I/O devices are involved in an
application,
• large number of block transfers are in your PLC program,
• PLC application is large,
• PLCs updates to discrete I/Os may increase the program scan
time.
• ASCII data is to be input using block transfers.
• Returning clock data to PLC.
Important: To use the Handshake feature with discrete transfers,
the PLC program must have a rung that accepts the handshake bit
and allows communications to continue. If you selected the
Handshake feature, the PLC program must contain this rung or the
DL40 Plus will not operate properly. If the DL40 Plus does not
detect the handshake for one minute, it will display the following
message: NO PLC HANDSHAKE

Message/Variable/Slave
Run Mode
8–17
In the Message/Variable/Slave run mode you can:
• trigger single messages through a PLC using the Remote I/O port
• send variables to be included in a message
• insert ASCII input data into a message
• return ASCII input data to a PLC
• return the message number of the message being run to a PLC
• send Real Time Clock or date data to a PLC
• place messages on Historical Events Stack
• require handshaking between DL40 Plus and PLC
• override slave address selected as a message attribute with an
address sent with the message trigger
Triggering Messages through a PLC
You can trigger a single message by either discrete I/O or a Block
Transfer Write. For details see pages 8–20 to 8–23.
Sending Variables to be Included in Message
Your PLC can include variables with the message trigger. Up to the
equivalent of 6 full word variables can be sent if using Discrete I/O
(depending on rack size) or up to the equivalent of 10 full word
variables can be sent using a Block Transfer Write (independent of
rack size).
Variable types include:
• 16 bit binary (1 variable per word)
• 8 bit ASCII (2 per word)
• 4 digit signed Binary Coded Decimal (BCD) (1 per word)
• 1 digit (4 bit) unsigned BCD (4 per word)
You can send variables via an RS-232/RS-485 link or the DL40 Plus
Keyboard Port. See Chapter 6, Serial Port Communications, for
more information.

Remote I/O Communications
Inserting ASCII Input Data in a Message
Use the Keyboard Port to input ASCII data intended for display.
• A request for ASCII Input data can be placed in a message by
inserting a [CTRL][X].
• A maximum of l20 ASCII characters can be requested for each
message triggered using Discrete I/O or Block Transfer Write.
• Requests for ASCII data can be strung together to form inputs
with a maximum of 20 ASCII characters.
• While a message is running, enter the ASCII character or string
of ASCII characters followed by a [↵ ].
See Chapter 6, Serial Port Communications, for more information.
Returning ASCII Input Data to a PLC
A maximum of 12 ASCII characters (depending on rack size) are
returned via Discrete I/O. A maximum of 20 ASCII characters are
returned via Block Transfer Read. See pages 8-21 and 8-24.
When all required ASCII data has been entered, the message will
time out and the Enter Bit in the Input Image Table will be set. It is
only after this bit is set that the data is considered valid.
Returning the Displayed Message Number to a PLC
This is automatically done in the Remote I/O scan. See pages 8-21
and 8–24.
Sending Real Time Clock or Date Data to a PLC
• Triggering special message 912 (or 12) causes the DL40 Plus to
send clock data to a PLC.
• Triggering special message 913 (or 13) causes the DL40 Plus to
send date data to a PLC.
For details, see pages 8–22 and 8-24. See chapter 3, Special
Messages, for more details on special messages.

Placing Messages on Historical Events Stack
Triggered messages and variable data can be placed on the 16 Kbyte
Historical Events Stack. The stack contents can be viewed/printed:
• in chronological order
• by number of occurrences
Handshaking Between DL40 Plus and PLC
Handshaking tells the sender (either the DL40 Plus or the PLC) that
Image Table Data was received.
Overriding a Slave Address with a New Message Trigger
To send any message to a slave, Port Use of the RS-485/RS-232 Port
must be set to DL Slaves.
Note: For this mode only, if your DL40 Plus is configured as a 1/4
rack device, you must specify the slave address as a Message
Attribute.

Message List Run Mode
In Message List run mode you can:
• Trigger a single message through a PLC via Remote I/O port
• Create a list of messages that are continuously displayed
• Place messages on the Historical Events Stack
• Send a message to the slave address selected as a message
attribute
• Insert ASCII data in a message
• Return ASCII input data to a PLC
• Return the message number of the displayed message to a PLC
• Send real-time clock or date data to a PLC
Creating a List of Continuously Displayed Messages
The list is created by adding message numbers to the list while the
DL40 Plus is in Run mode. See Chapter 6, Serial Port
Communications, for details on adding/deleting messages through
the RS-232/RS-485 port or the Keyboard port.
• Messages are displayed in the order they are put on the list.
• Messages can be added or deleted from the list while the list is
running.
• Unlike the Message/Variable/Slave run mode, you cannot send
variables to be included in a message.
• Messages are added to the end of the list. If a message is deleted
and re-added to the list, it is re-added to the end of the list.
• Special messages must be triggered only as priority messages in
the Message List mode.
• You can send a priority message number via the Remote I/O,
RS-485, RS-232, or Keyboard port which is queued as in the
Message/Variable/Slave run mode. When the current message has
run, all priority messages in the queue will run. Then, the DL40
Plus resumes running the Message List.
Important: The Message List is lost if you exit Run mode. Reset
the DL40 Plus or cycle power. You must create a new list when you
re-enter Run mode.
Placing Messages on the Historical Events Stack
Same as Message/Variable/Slave run mode but includes entries for
adding or deleting messages.
Note: If the message’s Historical Events Stack attribute is set,
message data is put on the stack once each time the message is
displayed or redisplayed.

Sending Messages to Slave Address Selected as a Message
Attribute
To send any message to a slave, set the Port Use of the RS-485 or
RS-232 Port to DL Slaves. See Chapter 6, Serial Port
Communications, for more information.
Note: If the message’s Print attribute is set, the message is printed
once each time it is displayed or redisplayed. The RS-232 port must
be set to Printer.
Inserting ASCII Input Data in a Message
Use the Keyboard Port to input ASCII data intended for display.
• A request for ASCII Input data can be placed in a message by
inserting a [CTRL][X].
• A maximum of l20 ASCII characters can be requested for each
message triggered using Discrete I/O or Block Transfer Write.
• Requests for ASCII data can be strung together to form inputs
with a maximum of 20 ASCII characters.
• While a message is running, enter the ASCII character or string
of ASCII characters followed by a [↵ ].
Returning ASCII Input Data to a PLC
A maximum of 20 ASCII characters (depending on rack size) are
returned via Discrete I/O. A maximum of 20 ASCII characters are
returned via Block Transfer Read. See pages 8–29 and 8–30.
When all required ASCII data is entered, the message times out and
the Enter Bit in the Input Image Table is set. It is only after this bit is
set that the data is considered valid.
Returning the Displayed Message Number to a PLC
This is automatically done in the Remote I/O scan. For details, see

Bit Trigger Run Mode
In Bit Trigger Run Mode you can:
• trigger a message by sending a bit trigger table
• return the message number of the message being run to a PLC
• place messages on the Historical Events Stack
• send messages to the slave address specified as message attribute
• insert ASCII data in a message
• send real-time clock or date data to a PLC
Triggering a Message by Sending a Bit Trigger Table
It takes only a single bit (set) to trigger a message. The position of a
bit (in the Bit Trigger Table) corresponds to a message number. Bit
00 of WORD 1 corresponds to message number 1; bit 01 of WORD
1 corresponds to message number 2; and so on. The total number of
messages that can be triggered depends on rack size allowed:

Sections of a Bit Trigger Table
The Bit Trigger table has 3 sections (all sent with a single transfer):
• Priority Message Number
• Priority
• Round Robin
Priority Message Number Section
When a priority message trigger is received (via Remote I/O,
RS-485, RS-232, or Keyboard Port), it is queued as in the
Message/Variable/Slave run mode.
After the current message runs, priority messages in the queue run.
• If no bits in the Priority or the Round Robin section changed, the
DL40 Plus returns to where it left off (in either section) and
resume running messages.
• If any bit in the Priority or the Round Robin section changed, the
DL40 Plus returns to the start of the Priority Section to resume
running messages.
The priority message can be any message including a special
message. Send the number of the message you want to trigger in the
Priority Message Number section of the Bit Trigger Table. If you
don’t want to trigger a priority message, leave this part of the table
empty (= 0).
Priority Section
Messages in this section are prioritized, starting with message
number 1 (corresponding to bit 00 of Word 1). This message has the
highest priority. The message with the highest priority (that has its
corresponding bit set) is displayed first. After the highest priority
message has run, the message with the next highest priority (with its
bit set) is displayed. The DL40 Plus continues to run through the
Priority Section displaying messages until the message
corresponding to the last set bit in this section is displayed.
Messages are displayed once for each change to the Bit Trigger table.
If an updated table (with a new Priority Message Number or at least
one bit in either the Priority Section or the Round Robin Section
changed) is sent to the DL40 Plus, the messages of the new Bit
Trigger Table run immediately even if messages in the old Bit
Trigger Table did not run. Messages with low priorities may never be
displayed. After the DL40 Plus displays all the messages in the
Priority Section (with bits set), the messages in the Round Robin
Section are displayed.
Note: The size (in words) of the Priority Section is set with the
Onboard Editor or with the Offline Programming Software.
Publication 2706-6.1
8–34
Remote I/O Communications
Round Robin Section
Messages with trigger bits set in this section are run after the priority
message and all messages in the Priority Section with bits set have
run. The DL40 Plus runs through this section displaying messages.
After the last message in this section is displayed, the DL40 Plus
returns to the first message (in this section) and starts again.
Messages continue to run until an updated Bit Trigger Table is sent.
After all priority messages in the updated Bit Trigger Table have run,
the DL40 Plus returns to where it left off in the Round Robin Section
and continues on from there.
Length of the Round Robin Section in (16 bit) words is:
• the length of the Bit Trigger Table (32 words)
• minus the Priority Message (1 word)
• minus the length of the Priority Section (X words)
Note: The lengths of the Priority Message, the Priority Section, and
Round Robin Section are always in full (16 bit) words.
For example, If the Priority Section is 9 words long, then the length
of the Round Robin Section would be:
=
32 words
-1 word
-9 words
22 words
In this mode, you can also:
• Return the message number of the displayed message to a PLC.
This is automatically done in the Remote I/O scan.
• Insert ASCII Input data into a message. Same as
Message/Variable/Slave run mode; except only returns data to a
PLC via RS-485/RS-232 Port. Note: Data is sent to Historical
Events Stack only if the Historical Event Stack Attribute is set.
• Send DL40 Plus’s Real Time Clock or date data to a PLC. Same
as Message/Variable/Slave run mode.
• Place messages on the Historical Events Stack. Same as
Message/Variable/Slave run mode but the Bit Image Table is put
on the stack each time it changes regardless of whether or not the
stack attribute is set. Note: If the message’s Historical Events
Stack attribute is set, message data is placed on the stack.
• Send Messages to the Slave Address specified as a message
attribute. If the message’s print attribute is set, the message is
printed once for each time it is displayed or redisplayed. Note:
To send a message to a slave, the Port Use of the RS-485 or
RS-232 Port must be set to DL Slaves. Refer to Chapter 6, Serial
Port Communications, for more information.

Bit Trigger Table
The Bit Trigger Table has 2 sections, the Priority section and the
Round Robin section.
With 1/4 rack, Bit Trigger Table must be either priority section or
round robin section. The length (in words) of the Priority Section is
set in the Offline Programming Software. The length of the Round
Robin Section is what is left over (total table length minus the
Priority Section length minus 1). With Discrete I/O, the length of the
table is 1, 3, 5, or 7 words long depending on rack configuration (1/4,
1/ , 3/ , full). With 16 bits per word, the maximum number of
2 4
messages that can be triggered with discrete I/O is 112 (total for
priority and/or round robin messages). The total length of the Bit
Trigger Table for Block Transfer is 32 words. With 16 bits per word,
the maximum number of messages that can be triggered is 496. Both
sections are in whole words. In addition, Priority Message Numbers
can be sent.

Electrical Precautions
Install the DL40 Plus using Publication NFPA 70E, Electrical Safety
Requirements for Employee Workplaces. In addition to the NFPA
general guidelines, use the following specific guidelines.
Careful cable routing helps minimize electrical noise. Route
incoming power to the module by a separate path from the
communication cables.
Do not run communications wiring and power wiring in the
same conduit!
Where communication and power wire paths must cross, make their
intersection perpendicular.
With solid state systems, grounding helps limit the effects of noise
due to electromagnetic interference (EMI). To avoid problems
caused by EMI, properly ground all equipment and use shielded
cables.
Input Voltage Requirements
Before connecting the Dataliner DL40 Plus to the incoming power,
verify that the power source and display type are in agreement.
The DL40 Plus will operate from 100-240 Volts AC, 50/60 Hz, 0.25
to 0.60 Amperes.
Power, input, and output (I/O) wiring must be in accordance with
Class I, Division 2 wiring methods [Article 501-4(b) of the National
Electrical Code, NFPA70] and in accordance with the authority
having jurisdiction.

Installation and Wiring
Remote I/O Connector
The Remote I/O connector on the back of the DL40 Plus connects
the DL40 Plus to the host PLC via the remote I/O link (Catalog No.
1746-RT29).
The Remote I/O link begins at the scanner module. The scanner
modules and programmable controllers impose physical and logical
limitations on the link. You must know these limitations to avoid
exceeding them.
To the rest of the system, the DL40 Plus looks like a Remote I/O
rack, and is addressed as such.
The maximum cable length (link distance) is limited by the baud rate
selected for the system:
10,000 feet (2,800m) for 57.6K baud
5,000 feet (1,400m) for 115.2K baud
2,500 feet (700m) for 230.4K baud
The actual connection is through a Catalog Number 1770–CD Serial
Data Link cable with a connector for the DL40 Plus.
Note: Use 150Ω, 1/2W. resistors to terminate links operating at 57.6
or 115.2K baud; use 82Ω, 1/2W. resistors to terminate links operating
at 230.4K baud.

9–9
Connect the DL40 Plus to the scanner module with Allen–Bradley
Remote I/O cable, Catalog Number 1770–CD (Belden 9463).
Refer to Programmable Controller Wiring and Grounding Guidelines
(Publication 1770–4.1) for detailed grounding and wiring guidelines.
The User Manual or Product Data Sheet for your scanner module
also provides cabling information.
Important: When first installed, the DL40 Plus may misinterpret the
hardware configuration if the DIP switch settings are not correct. If
the FAULT indicator flashes after installation, verify the DIP switch
settings and recycle power to clear the fault.
A connector plug is provided with each DL40 Plus. Wire the
connector to the remote I/O cable as shown here.

Before wiring the parallel input port, note the following:
• parallel input port accepts input voltages of 5 to 24VDC.
• GND terminal must connect to DC COM of the output module.
• the 12VDC output terminal can be used to power the VDC
terminal of the output module.
• you can use an auxiliary DC power supply of 5 to 24VDC instead
of the 12VDC output, but the DL40 GND terminal must connect
to the auxiliary power supply’s DC common terminal.
• MS0-MS3 message strobe lines must be connected (not shown).
• only use the minimum number of data lines (D0-D15) required
for your maximum message number or largest variable value.
• unused parallel port inputs are internally pulled low (off).
• parallel inputs are tied to isolated GND terminals via 2.35KΩ.
• each input draws approximately 2mA at 5VDC, 5mA at 12VDC,
10mA at 24VDC
• 12VDC terminal can provide up to 200mA for your application.

Installation and Wiring
Connecting a Programmer
to the RS-485 Port
When using a personal computer to upload or download application
memory to or from the DL40 Plus’s RS–485 port, use a Black Box
RS-485 converter, Model LD-485A-MP. The link from the personal
computer to the converter is an RS–232 link.
The following cable is recommended:
• for an AT style computer, use an Allen–Bradley 2706-NC15.
• for an XT style computer
Connect from the converter to the DL40 Plus as shown below.
Configure the converter as follows:
1. Remove cover and set the converter as a DCE device using the
XWlA jumper. This is a DIP shunt jumper.
2. Short TXA and RXA on TB1 of the converter. This should be
connected to J6, pin 5 of the DL40 Plus.
3. Short TXB and RXB on TB1 of the converter. This should be
connected to J6, pin 4 of the DL40 Plus.
4. Set switch W8 on the converter for full-duplex operation when
downloading or triggering messages via the RS–485 Port.
5. Set the RTS/CTS delay time to 5 milliseconds using jumper W9.
6. Set switch S2 to Unterminated position.
7. Replace cover.
8. Set Normal/Loopback switch on front cover to Normal.

The slave displays may be any combination of DL40 Plus displays,
DL50 Marquee displays, or equivalent devices compatible with the
Allen-Bradley slave protocol. The RS-485 network link supports
multi-drop communications with up to 126 slave displays. Use
Belden 9842 cable at a maximum length of 4,000 ft (1219 meters).
The following diagram shows a typical Dataliner DL40 Plus RS-485
network with one master DL40 Plus display communicating with
multiple slave displays.

Fast Reset Sequence (Switch #3)
If the Fast Reset DIP switch is set to ON, the DL40 Plus displays
only the Firmware Version, Screen Test, and the Selected Run Mode.
All other prompts are skipped (but the tests will still be run). If any
of the tests fail, then that error message will still appear. If the Fast
Reset DIP switch is set to OFF, the DL40 Plus displays the Firmware
Version, Memory Verification, External Module Verification, Screen
Test, RS-232 Port Settings, RS-485 Port Settings, Remote I/O
Settings, and the Selected Run Mode.
Block Transfer Enabled (Switch #4)
If the Block Transfer Enabled DIP switch is set to ON, then block
transfer files are used for communication with the PLC. If the Block
Transfer Enabled DIP switch is set to OFF, then Discrete I/O is used
to communicate with the PLC.
Last Chassis (Switch #5)
The Last Chassis setting tells the PLC if the DL40 Plus is the last
device of that logical rack, not necessarily the last rack of the remote
I/O link.

Keyboard Type (Switch #6)
If the Keyboard Type DIP switch is set to ON, then an IBM-XT or
compatible is the only type of keyboard that can be used. If the DIP
switch is set to OFF, then the IBM-AT or compatible is the only type
of keyboard that can be used.
Handshake Enable (Switch #7)
• With Block Transfer Enable Switch OFF. If the Handshake
Enabled DIP switch is set to ON this allows the use of the
handshake bit. Note: If Handshake (switch #7) is enabled, the
Handshake rung must be programmed in the ladder logic. See
page 8–16.
• With Block Transfer Enable Switch ON.
– Handshake Switch ON – DL40 Plus will indicate ERROR if
no block transfer reads are requested for one minute.
– Handshake Switch OFF – DL40 Plus will not generate error
message if no block transfer reads are requested. Messages
will continue to run.
Last State (Switch #8)
If set to ON (Last State enabled) and the DL40 loses communication,
the DL40 Plus will alternate the error message with the current
display. The DL40 Plus will still run messages triggered via the
keyboard or the RS-485 port.
If set to OFF (Last State disabled) and the DL40 loses
communication, the DL40 Plus clears the display and displays the
error message.
Select Button Enable (Switch #9)
When set to ON, then the [SELECT] button on the faceplate of the
DL40 Plus is enabled. In the OFF position, the [SELECT] button is
disabled.
No PLC Communications (Switch #10)
When set to ON, the No PLC Communication message is disabled.
In the OFF position, then the No PLC Communication message is
enabled.

Switch Bank #2 (SW–2) sets the serial address. The serial address
refers to the address used for triggers received from the serial
RS-485 port or computer keyboard.
Important: Remove power from The DL40 Plus before setting any
switch except Select Enable, SW1–9. Select Enable can be changed
with the power ON. Switch settings are scanned only on power-up.
The new setting for Select Enable takes effect immediately. The new

Debug (Switch #2)
When set to ON, then the current state of all of the parallel port
inputs is displayed on the DL40 Plus at power up. If the Debug
DIP switch is set to OFF, then the DL40 Plus enters run mode at
power up.
Fast Reset Sequence (Switch #3)
When set to ON, the DL40 Plus displays only the Firmware Version,
Screen Test, and the Selected Run Mode. All other prompts will be
skipped (but the tests will still be run). If any of the tests fail, then
that error message will still appear. If the Fast Reset DIP switch is
set to OFF, the DL40 Plus will display the Firmware Version,
Memory Verification, External Module Verification, Screen Test,
RS-232 Port Settings, RS-485 Port Settings, and the Selected Run
Mode.
Keyboard Type (Switch #6)
If the Keyboard Type DIP switch is set to ON, then an IBM-XT or
compatible is the only type of keyboard that can be used. If the DIP
switch is set to OFF then the IBM-AT or compatible is the only type
of keyboard that can be used.
Select Enable (Switch #9)
When set to ON, then the [SELECT] button on the faceplate of the
DL40 Plus is enabled. In the OFF position, the [SELECT] button is
disabled.

cause this message to appear (but only when the
DL40 Plus is in the Run Mode).
PLC not powered
Loose or pulled Remote I/0 cable
Reversed Remote I/0 cable wires
Incorrect baud rate
PLC not configured for this rack
While attempting to send data to the printer, an error
was detected on the RS–232 port. This can be
caused by a missing or incorrectly wired printer
cable, improper baud/data bit/parity selections, or
electrical noise picked up by the cable.
An invalid combination of rack size and starting
module group have been entered on the DL40 Plus
DIP switches. An example of such an error would be
a starting module group of 2, with a full rack size.

To enter an extended ASCII character, use the [ALT] key in combination
with the numeric keypad section on your keyboard. Hold down the
[ALT] key, then enter one of the decimal values found in the extended
ASCII character chart below. The selected character will appear in the
offline message window when you release the [ALT] key. Extended

Cyrillic Character Set
The DL40 Plus Dataliner supports both Cyrillic and English alphabet
characters. The Cyrillic characters include the 32 standard Cyrillic
alphabetic characters. The English characters include the standard 26
English alphabet characters, numbers, and punctuation marks. Refer to
the Cyrillic character reference chart that follows for keycode
assignments.

Accessing Cyrillic Characters
Russian language messages may be created and edited only within the
offline programmer. There are two ways to generate Cyrillic characters
using a standard IBM compatible keyboard. A full set of upper and
lower case characters can be generated in the Edit Message and Create
New Message screens of the offline programmer.
Using the Cyrillic character reference chart on the previous page, a
character can be entered by holding down the ALT key while
entering the decimal number corresponding to the desired character.
Releasing the ALT key will then display the normal corresponding
extended ASCII character. When the message is downloaded to the
DL40 Plus, the characters are converted to Cyrillic.

International Character Set
To access the international character set, also called Latin Alphabet
No.1, use the [ALT] key in combination with the numeric keypad section
on your keyboard. Hold down the [ALT] key, then enter the 2-digit
hexadecimal value found in the chart below. For example, to enter &,
you would hold down [ALT] then enter the value 26. The normal
corresponding ASCII character is displayed in the offline message
window when you release the [ALT] key. When you download the

Parallel Port Message Variable Slave Triggering Example
This example shows message triggering through the parallel port.
This SLC program triggers a message using the parallel port (Message Variable Slave Mode).
A 1 sent to the strobe lines indicates that the data lines contain the number
of the message being triggered.

In this example, the strobe lines are the first four outputs in a 1746-OB16
output module located in the fourth slot of the SLC rack. Since the outputs
are the four least significant lines, a 1 sent to the output module makes
MS0 a 1 which indicates the data lines contain a message number.

Parallel Port Message List Mode Triggering Example
This example shows message triggering through the parallel port.
This SLC program triggers a message using the parallel port (Message List Mode). This example uses a
1746-OB16 output module with the four least significant output lines tied to the strobe lines of the DL40 Plus.
Enter: 1 to send a Priority Message
2 to add a message to the list
3 to delete a message from the list
