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:

/2, 3/4, or full).

• 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

Introduction to the DL40

Operating Modes

The DL40 Message Display offers a number of operating modes from which to choose. Each provides you with the tools you need to perform a different set of functions. The following paragraphs and the tables that accompany them provide a brief overview of the various operating mode options available to you.

Run Mode

Run Mode is the normal operating mode for the DL40. In Run Mode messages are triggered for display on the DL40 and (if desired) on slave message displays.

The Remote I/O version of the DL40 always comes up in the Run Mode after reset. The Parallel Port version does, too, except when the message display’s Run Mode/Debug DIP switch is set to Debug.

Remote I/O DL40s offer four types of Run Modes:

• Message/Variable/Slave

• Message/Variable

• Message List

• Bit Trigger

Parallel Port DL40s offer two types of Run Modes:

• Message/Variable/Slave

• Message List

You can select the type of run mode you want as an Option using the Onboard Editor or Offline Programming Software.

Other Operating Modes

In addition to the Run Modes described above, the DL40 offers the following operating modes:

• Help Mode

• Historical Recall Mode

• Remote Program Mode

• Backup Mode

• Set RS-232/RS-485 Port Mode

• Clock Mode

• Print Mode

• Debug Mode (on parallel port versions only)

Chapter 2

Introduction to the DL40

Note that you will use the Remote Program Mode whenever you use the Offline Programming Software.

Special Messages

Triggering Special Messages gives you the ability to monitor and control certain functions of the DL40 without leaving Run Mode. These messages normally occupy Message Numbers 901 to 916. You can move Special Messages to Message Number 1 to 16, or disable them with the Offline Programming Software or Onboard Editor. You will find a complete explanation of Special Messages in Chapter 5.

Message/Variable Run Mode

Message List Run Mode

Message/Variable Run Mode can only be selected via the Offline Programming Software. It is the same as the Message/Variable/Slave Run Mode except:

• You cannot override the slave address selected as a Message Attribute.

• Your PLC can send up to the equivalent of 7 (not 6) full word variables if

using discrete I/O.

In the Message List Run Mode you can:

Create a List of Messages that is Continuously Displayed

The list is created by adding message numbers to the list while the DL40 is in the Run Mode. See Chapter 10 for information for adding (or deleting) messages via the Remote I/O Port. See Chapter 8 for additional information for adding (or deleting) messages via the RS-485 Port or the Keyboard Port.

Important: The Message List will be lost if you leave the Run Mode, reset the DL40, or cycle power. You will have to create a new list when you re–enter the Run Mode. In addition:

• 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 always added to the end of the list. If a message is deleted

and re-added to the list, it will be re-added to the end of the list.

• You can send a Priority Message Number via the Remote I/O, RS-485, or

Keyboard port 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 resumes running the Message List.

See Chapter 10 for more information. Note: Unlike the Message/Variable/Slave Run Mode, you cannot send

variables to be included in a message. The Bit Trigger table has three sections (all three sections are sent with a

single transfer):

Priority Message Number Section

When a priority message trigger is received (via Remote I/O, RS-485 or Keyboard Port), it 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.

• If no bits in either the Priority Section or the Round Robin section have

been changed, the DL40 will return to where it left off (in either section) and resume running messages.

• If any bit in either the Priority Section or the Round Robin section has

been changed, the DL40 will return to the start of the Priority Section to resume running messages.

The Priority message can be any message even a Special Message. Send the number of the message you want to trigger in the Priority Message Number Section of the Bit Trigger Table. See page 10-24. If you don’t want to trigger a priority message, leave this part of the table empty (i.e.

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) will be displayed first. After the highest priority message has completed running, the message with the next highest priority (with its bit set) will be displayed. The DL40 will continue to run through the Priority Section displaying messages until the message corresponding to the last set bit in this section has been displayed.

Messages are displayed only 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, the messages of the new Bit Trigger Table will begin to run immediately even if messages in the old Bit Trigger Table were not run. It is

possible that messages with low priorities may never be displayed. After the DL40 has displayed all the messages in the Priority Section (with bits set), the messages in the Round Robin Section will be displayed.

Note: The size (in words) of the Priority Section is set with the Onboard Editor or with the Offline Programming Software.

Round Robin Section

Messages with trigger bits set in this section will be run after the Priority Message and all messages in the Priority Section with bits set have been run. The DL40 will run through this section displaying messages. After the last message in this section has been displayed, the DL40 will go back to the first message (in this section) and start again. Messages will continue to run until an updated Bit Trigger Table is sent. After all priority messages in the updated Bit Trigger Table have been run, the DL40 will return to where it left off in the Round Robin Section and continue 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

The Run Mode – Parallel Port

This chapter describes the operations of the Run Mode for the Parallel Port version of the DL40. Refer to Chapter 3 for information on the Run Mode for Remote I/O versions of the DL40. See Chapter 6 for information on other operating modes. Refer to Chapter 9 for additional technical information on using the parallel port.

Run Mode is the normal operating mode for the DL40. In Run Mode, messages are triggered for display on the DL40 and (if desired) on slave message displays.

The Parallel Port version of the DL40 always comes up in the Run Mode after reset, except when the message display’s Run Mode/Debug DIP switch is set to Debug.

Parallel Port DL40s offer two types of Run Modes:

• Message/Variable/Slave

• Message List

You can select the type of run mode you want as an Option using the Onboard Editor or Offline Programming Software. Table 4.A provides an overview of the differences between Run Mode Types.

The Run Mode – Parallel Port

Insert ASCII Input Data Into a Message

Use the DL40 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]. See Chapter 5 for more information.

• Up to 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 up to 20

ASCII characters long.

• While a message is running, enter the ASCII character or string of ASCII

characters followed by a [↵ ].

Return ASCII Input Data to a PLC

Up to 20 ASCII characters are returned via the RS-485 Port.

Message List Run Mode

Put Messages on Historical Events Stack

Both 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 display or printed:

• in chronological order

• by number or occurrences

Override Slave Address Selected as a Message Attribute with an Address Sent with the Message Trigger

To send any message to a slave, Port Use of the RS-485 Port must be set to DL Slaves. See Chapter 6.

In the Message List Run Mode you can:

Create a List of Messages that is Continuously Displayed

The list is created by adding message numbers to the list while the DL40 is in the Run Mode. See Chapter 8 for additional information for adding (or deleting) messages via the RS-485 Port or the Keyboard Port.

Important: The Message List will be lost if you leave the Run Mode, reset the DL40, or cycle power. You will have to create a new list when you re–enter the Run Mode. In addition:

• Messages are displayed in the order they are put on the list.

4–3

Chapter 4

The Run Mode – Parallel Port

• Messages can be added to or deleted from the list while the list is running.

• Messages are always added to the end of the list. If a message is deleted

and re-added to the list, it will be 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 resumes running the Message List.

Note: Unlike the Message/Variable/Slave Run Mode, you cannot send variables to be included in a message.

Insert Request for ASCII Input Data With [CTRL][X]

A data request requires that ASCII Input Data (an 8-bit ASCII character) be entered through the keyboard port into the message being displayed.

• When returning ASCII Input Data via RS-485 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 [↵ ].

Note: Data is returned to the triggering device without solicitation by the device and without an checking that data was received by the device.

• With Remote I/O units, the ASCII input data will be sent via Remote I/O

Port to your PLC as part of the Return Message Number Being 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, depending on rack size.

The Enter bit will be set only after all ASCII data requested has been put into the message. Data should not be 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 will be 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 With [CTRL][T]

To enter the time into 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).

Note: The time variable occupies 8 of the available 20 characters on a display line.

You can use the time variable in any Run Mode.

7–6

Insert Date Into a Message With [CTRL][Y]

To enter the date into a message, place the cursor just after the point where you want the date to appear, and then press [CTRL][Y]. The software will insert the date symbol (DAY MON YR).

Note: The date variable occupies 10 of the available 20 characters on a display line.

Chapter 7

Messages

You can use one date variable in any message in any Run Mode.

Note

We recommend setting individual message attributes such as Display Line and Scroll Message before typing in the words of the message. This allows you to verify the placement of characters as you type them.

Testing Messages

Message Attribute Defaults

Pressing [CTRL][R] while editing a message runs the message you are editing just as it would be displayed in the Run Mode except:

• Message will not be put on Historical Events Stack

• Time and Date are not put on Historical Events Stack

• Special Messages cannot be run

• [CTRL][V] and [CTRL][W] variable data will not be displayed in a

message. They are represented by asterisks (****)

• [CTRL][X] Data Requests will be represented by underscores (_ _ _ _).

Values for Data Requests can be put into a message for testing using a keyboard

• Data cannot be returned via Remote I/O or RS-485 port

The Message Attribute Defaults apply universally to all messages when they are created. (You can modify the message attributes for an individual message by using [CTRL][A] while editing that message.) The modifiable message attributes you can control from the Online Editor appear below, along with a brief description of their use.

• Display message on what line

Note: The following Message Attributes are new in Version 3.00 or later firmware and can be accessed only through the Offline Programming Software (Catalog No. 2706-ND1, Series D, Ver. 3.00 or later):

• Slave Color

• Slave Relay

• Slave Length

Display Line

This value controls where on the DL40 display the message will appear. Options are different for 2 and 4 line versions. Use the spacebar to move through the available choices, then press [↵ ] when you see the correct value.

With 2 line units, choose from With 4 line units, choose from

All Lines All Lines Line 1 Only Line 1 Only Line 2 Only Line 2 Only

Line 3 Only Line 4 Only

Scroll Message

This message attribute determines whether the message will scroll across the DL40 Message Display. You can activate scrolling only if the Line Usage attribute (described above) has been set to use 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 Message Display will send any triggered message to a printer via the DL40 RS-232 Port. The message will be printed only once (even if the Auto repeat attribute is active) unless the message contains changed variable data. 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.

Send to Slave

If you enter a slave number here and a message is triggered via the Remote I/O or Parallel or Keyboard ports, the message will be sent to the slave with the specified address. This attribute is valid for all Run Modes. However, the slave address set when operating in the Message/Variable/Slave Run Mode overrides this attribute.

7–8

Chapter 7

Messages

Important: To send any message to a slave, Port Use for the RS-485 port

must be set to DL Slave. Refer to page 6 – 12 for information on Ports.

If the AutoReplace attribute is active, the message will be sent to the slave each time it repeats. If the message has embedded variables, it will be 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

Wait Time

This setting can mean either of two things to the message display. If you have activated Scroll message, the value here represents the

scrolling rate in tenths of a second. For example, a value of 8 here will result in 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 will appear on the message display. For example, a value of 5 here will assure that the message will appear on screen for 5 seconds whenever it runs.

Acceptable values for this field can range from 0 through 31.

AutoClear

Activating this attribute instructs the DL40 to clear the message from the display after the Wait Time for message has expired even if no other messages have been triggered.

This value applies only to the lines used by a single message. For example, if this message uses only lines 2 and 3, then only lines 2 and 3 will be cleared. Lines 1 and 4 will remain unchanged.

Important: AutoClear will de-energize the alarm relay only if the message

which was cleared had energized the relay. A DL50 slave message display must always be sent a message that de-energizes the relay.

Type [Y][↵ ] to activate or [N][↵ ] to deactivate.

Chapter 7

Messages

AutoRepeat

This attribute causes the display to repeat a message continually as long as no other message is in the queue waiting to run. This attribute only functions if the DL40 message display is operating in the 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

With this attribute you can link two messages together so that the second message will run 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 will have 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: The Chain to Msg attribute will be disabled if AutoRepeat is active. Activate this attribute by entering a valid message number.

Energize Relay

Activating this attribute will display the message and energize the DL40 message display’s alarm relay whenever the message is triggered.

Important: 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 DL40 message display leaves the Run Mode

Important: AutoClear will de-energize the alarm relay only if the message

which is cleared 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

When a message is triggered, enabling this attribute will put the message number on the Historical Events Stack. Variables will also be placed on the stack. Stacked messages can also be time stamped with the time the message was triggered and/or run.

Important Even if AutoRepeat is enabled, the message number (and time)

will be 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) will be put on the Historical Events Stack while the message is running or repeating only when updates to variables are received by the DL40

Type [Y][↵ ] to activate or [N][↵ ] to deactivate.

Stack Time

Enabling this attribute allows for time and date stamping of messages sent to the Historical Events Stack.

Type [Y][↵ ] to activate or [N][↵ ] to deactivate.

Hide message

When activated, the message will not appear on the DL40, but rather will be sent to a slave display, printer, tape recorder, or placed on the Historical Events Stack. The other attribute settings for the message determine its destination(s).

For example, assume Hide message is enabled, as are Print message and Send to slave 2. There will be no change on the DL40 display when the message runs, although a copy of the message will be printed and it will be displayed on the slave addressed as 2.

Note: When used with [CTRL][X] (ASCII Input Data), the underscore prompt for this data will still be displayed on the DL40 message display even when Hide message is active.

Type [Y][↵ ] to activate or [N][↵ ] to deactivate.

Introduction

Port Usage

Chapter 7

Serial Communications

This chapter explains the use of the three serial communication ports on the DL40.

Note: The Remote I/O instructions appear in Chapter 11.

Serial communications with the DL40 are made via three ports located on the back panel of the DL40:

• the RS-232 Port

• the RS-485 Port

• the Keyboard Port

Each port can be used to perform a different set of tasks. A summary of potential uses for each port appears below. You can use the RS-232 Port for:

Port is described in Chapter 10. Wiring and cabling

Uses of the RS-232 Port

•

Direct (point to point) uploading or downloading of message files up to 50 feet (15.24 m.). Refer to the Dataliner DL40 Series Message Display Offline Programming Software User Manual (Publication 2706-808) for information.

• Reading or writing a DL40’s Internal Application Memory from or to a

tape.

• Printing the Historical Events Stack.

• Printing messages as they are triggered for display (if the Print Message

attribute is set).

• Printing user application file (parameters and messages).

• Test displaying messages.

• Setting DL40 using computer’s real time clock.

Uses of the RS-485 Port

Multi-drop uploading and downloading of message files.

•

• Communicating to a slave message display.

Note: To send messages to a slave, Port Use of the RS-485 Port must be set to DL Slave.

Chapter 8

Serial Communications

• Triggering messages in any run mode.

• Inputting variable data in the Message Variable/Slave Run Mode and

Message/Variable Run Mode.

• Dynamically adding or deleting messages to or from the list in Message

List Run Mode.

• Test displaying messages.

• Setting DL40 using computer’s real time clock.

• Returning [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.

Note: If more than one DL40 is on the RS-485 link and — if a transmission is in progress to a DL40 and

— if power to a second DL40 is cycled (OFF–ON), the transmission to

the DL40 will time out because the DL40 which is powering up temporarily interrupts the link (this does not occur with displays having a firmware revision number of 2.02 or greater).

Uses of the Keyboard Port

Use the Keyboard Port to control a variety of DL40 functions.

You can also use the Keyboard Port for:

• Inputting ASCII Input [CTRL][X] Data.

Note: ASCII Input Data can only be returned via the RS-485 Port if the message was triggered via the RS-485 Port or via the Remote I/O Port if the message was triggered via the Remote I/O Port.

Note: If 0 or no slave address is input, the slave address selected as a message attribute is used.

Note: The DL40 address is optional if triggering a message via the keyboard. If no DL40 address is sent, the message will be triggered on the DL40 that the keyboard is plugged into. If a DL40 address is specified, the message will run only if the address is 127 or if it matches the address of the DL40 that the keyboard is plugged into. If no DL40 address is sent when using the RS-485 link, the message trigger will be ignored.

If no DL40 address is sent, the second backslash ( \ ) is optional. If no Slave Address or DL40 Address is sent, both backslashes are optional. Note: If the Remote I/O Port is inactive or faulted, the Last State switch

(number 8 on SW2) must be ON to trigger messages from the keyboard or via the RS-485 Port.

Selecting Data Format

The parallel port uses either the binary numbering system or the 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. You must select which numbering system best suits your needs, and then set the parallel port to the selected data format using the Onboard Editor or Offline Programming Software.

Each numbering system, binary or BCD, has its own merits. Your choice will often be based upon the format used by your controller. However, the use of binary numbers to input variables allows you to use variable data in the range of –32,768 to +32,767 (2’s complement binary). If you use BCD numbers to input variable data, the variable may range in value from –9,999 to +9,999.

Using Binary Data Input

A data line may either be at ground level or have a voltage present. The convention of having a voltage represent a value of 1 and ground representing a value of 0, is known as High True Logic. The opposite convention is called Low True Logic. You can set the DL40 to accept either High True or Low True Logic using the Offline Programming Software. Table 9.B shows the value of each data line.

Logic Voltage Levels

Adding the values of the individual data lines provides the value being entered, in this case 5545.

Each parallel input interprets two voltage levels: ON or OFF. There is also a third state which should be avoided, an “I don’t know” or “indeterminate” state. The “indeterminate” state occurs when the voltage is between the ON voltage range and the OFF voltage range. Table 9.F lists the voltage levels and their logic values.

High True Logic Low True Logic

You can select either the High True or Low True Logic using the Offline Programming Software.

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 (Catalog No. 1771-OB, 1746-OB8, or 1746-OB16) and AC Output Module (Catalog No. 1771-OA). Two 2706-NG2 AC input converters are required

Chapter 9

Using the Parallel Port

with the AC Output Module. The ISO +12V connection can be used to power the DC connections of the 2706–NG2 AC input converters.

Message/Variable/Slave Run Mode

Triggering rules:

• When used, 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 sent are always associated with the last message triggered:

– if the message is in the queue, variables will be put into the queue

(with the message) and onto the Historical Events Stack.

– if message is running and variable is being displayed, the variable will

be updated with the latest data this data will also be put onto the Historical Events Stack.

– if message is running and variable is no longer being shown (as in a

scrolling message), updated data will not be shown but will be put on Historical Events Stack.

– if message has completed running, updated data is lost to display and

to the Historical Events Stack.

• BCD Sign Bit

Only valid for [CTRL][V] BCD variables; not valid for [CTRL][W] BCD. –

Set = –

– Clear = + – Sign bits must precede variables. The sign cannot be changed without

resending the variable.

– Bit 0 = Variable l – Bit 1 = Variable 2, etc. – Bits 9 = 15 ignored – No Sign Bit sent (default) = +

Note: For BCD variables only. Ignored for binary and ASCII variables. To sign a binary variable, use 2’s complement.

(Ctrl V) variables 1–10

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 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 (See NOTE below)

If the variables were not numbered as shown, they would be displayed in wrong positions and possibly corrupted.

9–6

Note: [CTRL][V] variables always use a (16 bit) word;

[CTRL][W] variables do not use a full (16 bit) word.

• 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.

• If [CTRL][W]s are BCD (4 bit) variables, the [CTRL][W] in the second

position

would be sent in the high nibble of the high byte of Variable 4;

Chapter 9

Using the Parallel Port

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

Sampling

In the Message List Run Mode, messages are continually being displayed by the DL40. 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.

The 4 strobe lines specify an instruction to be performed.

to add

While the DL40 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 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 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 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 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 too for a minimum of 5 msec (plus switching delay time).

Using the Parallel Port

AC Sampling

Important: 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.

Chapter 9

Using Remote I/O

This chapter discusses communication and compatibility considerations related to using the DL40 Message Display with programmable controllers. Topics also include the Remote I/O architecture and factors in calculating rack size, as well as triggering messages.

The Remote I/O version of the DL40 Message Display communicates with all Allen-Bradley programmable controllers that support the Remote I/O link.

These displays communicate with PLC controllers and Remote I/O scanners and sub-scanners as if they were a Remote I/O rack. The displays contain all the necessary electronics to connect directly to the Remote I/O cable that originates from a PLC, scanner, or sub-scanner. These scanners have both physical and logical specifications which are as follows:

Physical Specifications – The maximum number of separate Remote I/O devices (I/O racks, drive systems, DL40s, etc.) the scanner can communicate to.

Logical Specifications – The maximum number of racks the scanner can address.

Note: Different scanners have different physical and logical specifications. Please refer to Table 10.E (Remote I/O Configuration) for these specifications.

To configure DL40s with the PLC controllers you need to know:

1. The appropriate PLC or scanner module. This is found in the next section, Remote I/O Architecture.

2. The amount of I/O the DL40 uses for different applications.

3. The number of chassis (1771 I/O racks or DL40s) and the amount of rack I/O addressing the scanner can accommodate.

To further explain Physical and Logical specifications, and to help you properly configure your Remote I/O architecture, please refer to the following 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 1 full rack

The example given is also within the

= 1 logical rack = 1 logical rack = 1 logical rack = 3 logical racks

3-rack logical limitation of the PLC

5/15.

10 – 5

Chapter 10

Using Remote I/O

An invalid Remote I/O configuration for a PLC 5/15 would be:

(8) 1/2 racks.

Corresponding Publications for Processors and Scanners

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. Therefore (8)1/2 racks is an invalid Remote I/O configuration for the PLC 5/15.

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.

The DL40 is compatible with all Allen-Bradley scanners that support Remote I/O.

Remote I/O Configuration

Once you have selected the appropriate scanner for a PLC controller, use Table 10.E to find out how many separate chassis or devices that 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) connected to the cable gives the number of full racks of I/O being supported by the scanner or sub-scanner for that application.

Triggering Messages

10 – 8

With the Remote I/O version of the DL40, messages are normally triggered from a PLC connected to the DL40. However, messages can also be triggered via the Keyboard Port or the RS-485 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.
