Intended Audience

Conventions

No special knowledge is needed to enter or edit messages. However, since the Dataliner message display must be connected to peripheral equipment, you should be familiar with computer communication terminology.

The following conventions are used:

• Messages displayed on the DL5 are shown inside a rectangular box.

(',7"

• A symbol or word in brackets represent a single key that you should press. These include keys such as [A] or [Retrn].

• Since the DL5 can be programmed with a variety of terminals, the printing on your terminal keyboard may be different than the symbol or word indicated in brackets. In this manual, we use [ Retrn] to specify t he carriage return function of the keyboard. On your keyboard this may

correspond to the [Enter] or [ ] keys.

• Angle brackets, < >, are used when you are to enter variable data. For example, <message number> , means you are to enter a message number at that point.

2706-UM001A-US-P

• In the following chapters, we refer to the Dataliner DL5 Series Message Display as the DL5.

Introduction to the DL5

Chapter 1

Chapter Objectives

Overview

This chapter briefly describes some of the key features and operating capabilities of the DL5. If you require more detailed information, refer to the section of the manual that describes the use of the feature or operating capability.

The DL5 stores messages of varying length within its own memory. The stored mes sages are displayed when the DL5 receives a command from your control system. The messages can be used to show a status condition, help diagnose a problem, or prompt an operator.

The Bulletin 2706 DL5 Series Dataliner Message Display (DL5) is available with two display options:

• One line d i splay (16 ch aracters)

• Two line display (16 characters per line)

Note: The operation of the one and two line displays is similar. The few exceptions are noted in this manual.

You can use a variety of devices to program the DL5

• The Allen-Bradley line of industrial terminals (T1 through T4).

• Most DTE type “dumb” terminals.

• DEC VT100, VT101 terminals.

• IBM compatible computers, including Allen-Bradley RAC6000

industrial computers, using the DL5 offline programming software (Catalog No. 2706-NP5).

• The 16 character display can show a wide variety of characters and symbols, including:

– Uppercase letters – Punctuation

1-2 Introduction to the DL5

Main Features

Serial or Parallel Triggering - Stored messages can be triggered by sending messages to the DL5 serial or parallel ports. Both the serial and parallel ports cannot be used at the same time. The Serial Trigger/ Configure DIP switch (S W1-1) on the back of the DL5 determines wh ich port is used for triggering.

DC Input - The parallel port of the DL5 accepts 5-24 volts DC. DL5s are powered by 12-24 volts DC.

Round Robin Mode - The round robin mode allows you to replace up to sixteen pilot lights, that are being used as status indicators, with a single DL5 display. Instead of your control system turning on a pilot light, it will trigger a message for display.

Priority Mode - The priority mode is similar to the round robin mode. However, the priority mode has an additional feature that allows you to designate certain messages as more important than other messages. If two or more messages are triggered at the same time, only the priority message will be displayed.

Numeric Mode - The numeric mode allows you to use the DL5 as a numeric only 3 or 4 digit (BCD) display. Your control system can transmit real time binary coded decimal (BCD) data to the DL5 for immediate display. Use the DL5 to display numbers as large as

999, 999, 999, 999, 999.

Binary or BCD Input Mode - Your control system can transmit data and message triggers in eit her bina ry or Binary Coded Decimal (BCD) formats. This allows the recall of up to:

• 94 messages with a one or two line 2K byte DL5

• 387 messages with a two line 8K byte DL5

Debug Mode - You can verify the operation of the program in a host programmable controller (PLC) using the debug function of the DL5. The debug mode will display the condition (ON or OFF) of the sixteen parallel port data lines.

Note: Special application considerations may be necessary for some types of controlling devices. Refer to Chapter 8 for more details.

2-6 Getting Started

Responding to a Yes or No Prompt

There are three types of prompts that require a response:

• Yes or No prompts

• Numeric prompts

• Mnemonic prompts

The yes or no prompts appear as a word or words followed by a question mark (?). You must respond to a yes or no prompt with either t he let ter “Y” (Yes) or the letter “N” (No). For example, the following prompt appears:

(',7"

If you press the [N] key (upper or lowercase), the display will show:

(',7"1

You can change your mind by pressing the [Y] key (upper or lowercase). The display now shows:

(',7"<

Note: Only the letters “Y” or “N” are accepted as responses. You may change your response as many times as you wo uld like prior to pre ssing the [Retrn] (carriage return) key.

If you press the [Retrn] key the selection is entered into the DL5’s memo r y and the next prompt will be displayed.

A variation of the yes or no prompt is the default prompt. The default prompt provides an initial response or “default” for you. For example, assume the following prompt is displayed:

)/$6+0(6*"1

If you press the [Retrn] key, the response “No” would be entered into the DL5’s memory. If you press the [Y] key, the prompt response will change as in the previous example:

)/$6+0(6*"<

2706-UM001A-US-P

Getting Started 2-7

Responding to a Numeric Prompt

The other type of prompt you will encounter is the numeric prompt. You must respond to a numeric prompt with a number. A numeric prompt will appear as a word or words followed by a colon (:). For exampl e, assume the following prompt is displayed:

180%(5

If you were to press the key [2] the display would appear like this:

180%(5

Pressing the key [7] will cause the display to change as follows:

180%(5

Notice that the numbers that are ente red scr oll in f rom the right side. If you really wanted to enter the number “5”, you could type the new number in over the previous r espons e by fir st ty ping in fou r zeroe s (0000 ) foll owed by the desired number “5”.

Pressing the [Retrn] key will now enter your response into the memory of the DL5 and the next prompt will be displayed.

Numeric prompts may also have default values. For example, when the following is displayed:

:$,77,0(

To record the number “5” as your response, press the [Retrn] key. If you want to enter another value, type over the default.

Press the [2] key, the display will show:

:$,77,0(

If you press the [Retrn] key, the number “2” would be entered as your response for the wait time.

Chapter Objectives

Edit vs. Run Mode

In this chapter you will learn:

• How to assign attributes to a message. Message attributes define how a

message will be displayed.

• How to enter messages.

Using the DL5 is a three step process:

1. First, mes sages are entered into the DL5’s memory w hile in the edit

mode.

2. Next, the run mode, autorun message, and operating characteristics of

the serial and parallel ports are selected using the special functions menu.

3. Finally , the DL5 is put in the run mod e. In the run mode external devices

trigger the DL5 to display stored messages or re al time variables. The attributes selected for each message, such as flash message, scroll, etc. will control how each message is displayed.

Selecting the Edit Mode

You can either enter a new message or edit an existing message by selecting the edit mode. You select the edit mode by press ing t he [Y] key in r esponse to the EDIT? prompt.

Note: To get the EDIT? prompt from the RUN mode, press [Esc] three times, answer [N] to RUN?, and press [Retrn].

Once you have entered the edit mode, the DL5 will display a series of prompts. Refer to the next page for a flow chart of the edit mode menu.

Important: Menu shown is for a 2 line DL5. One line displays do not have the prompts (USE BOTH?, USE LINE 1?, USE LINE 2?, USE LEAST?).

Specifying Message Attributes

After you have entered the edit mode and sel ected a new message n umber to edit, you must specify t he message attributes. T he message attributes determine how the message is displayed. The DL5 prompts for each attribute, one at a time. You must respond to all the attribute prompts that are displayed.

Note: If any attribute setting is changed and then the [Esc] key is pressed three times, the changed attribute is not saved. It is necessary t o carriage return through all attribute settings to change one of them.

Some message attributes are mutually exclusive; you can select either one, but not both. Refer to the edit menu diagram (previous page) and the following descriptions when specifying message attributes.

Line Selection

If you are using a single line DL5, there are no line selection prompts and you should refer to the next section.

If you are using a two line DL5, the first message attribute that you must specify is the line, or lines, that the message will be displayed on. There are four options:

• 1) USE BOTH

• 2) USE LINE 1

• 3) USE LINE 2

• 4) USE LEAST

As the DL5 (two line only) displays a line selection prompt, you must respond with either a [Y] (Yes) or [N] (No) response. If you respond to a prompt by pressing the [Y] key followed by the [Retrn] key, the message attribute is enter ed int o the memory of the DL5. If you re spond by p ressi ng the [N] key followed by the [Retrn] key, the next line selection option will be displayed. The following sections describe what effect each option has on the displayed message.

2706-UM001A-US-P

USE BOTH?

Selecting the USE BOTH option will au tomat i cal ly displ ay the message on both lines of the display as a line mode message. A multi-line message will display with the firs t li ne o f the message on the f irst line of the displ ay. The next line of the mess age is dis played on the sec ond line of the displa y. If th e message is longer than the number of lin es of the displ ay, the DL5 will wait for the “wait time,” and then show the remaining lines of the message.

USE LINE1?

The USE LINE 1 option displays the message only on the first (top) line of the display. Any messages present on the second line (if any) will remain intact.

USE LINE2?

The USE LINE 2 option displays the mes sage only on th e second lin e of the display. Any messages present on the first line of the display (if any) will remain intac t.

USE LEAST?

The USE LEAST option displays the message on the l east recently u sed line (oldest lin e of information). Any messages present o n the other li ne of the display (if any) will remain intact.

Selecting Line or Scroll Mode

If you are using a si ngl e l in e DL5, the first prompt you will see displayed is the prompt for the line or scroll mode option. The prompting for line or scroll mode will also be displayed if you are using a two line DL5 and you did not choose the USE BOTH di spl ay opt i on. The prompt will appear li ke this:

SCROLL MODE?

If you do not select the SCROLL MODE option, the line mode will be automatically selected.

• Scroll Mode – A scroll mode message scrolls across the display one

character at a time. Characters enter from the right side of the display and exit on the left.

• Line Mode – A line mode message is displayed one message block (16

characters) at a t ime. Many of the mes sages th at you cr eate may be more than one block long. If a message is made up of more th an one messa ge block, the DL5 will display a message block for the specified wait time and then display the next blocks of the message.

Remember: If you are using a two line DL5 and selected the BOTH LINES option, the line mode will be selected automat ically. You will not be prompted for the SCROLL MODE option.

Selecting Message Wait Time

The next message attrib ute that you must select is the message w ait time. The message wait time controls how long a message or a portion of a message is displayed. The prompt for the message wait time appears like this:

WAIT TIME:

You must enter a wait time value betwe en 0 and 15. The uni t of time bei ng selected depends upon whether line or scroll mode was chosen.

• If the scroll mode has been selected, the wait time is the amount of time

that elapses before the next character is scrolled on the display. The unit of time is in tenths of a second.

• If the line mode has been selected, the wait time is the amount of time

that a message block is displayed. The unit of time is in seconds.

3-6 Entering New Messages

Auto Clear Option

The next prompt that you must respond to controls whether or not the display will clear after the message is shown. The prompt appears like this:

AUTO CLEAR?

If you select the AUTO CLEAR option, the DL5 will clear the displa y after the message has been displayed for the requested wait time. If you do not select the AUTO CLEAR option, the last block of the message will remain on the display until it is replaced with another message.

Auto Repeat Option

The next prompt that you must respond to allows a message to be repeated indefinitely. The prompt for the AUTO REPEAT option appears like this:

AUTO REPEAT?

If you select the AUTO REPEAT option, the message continually re-trigger s itself after it completes its display. If you do not selec t the AUTO REPEAT option, the DL5 will display the message only once for every message trigger that is received.

Note: The AUTO REPEAT function will only work with message triggers that are in either binary or Binary Coded Decimal (BCD) format. The function will not work when the DL5 is in the round robin or priority mode of operation.

Flash Message Option

The last prompt determines whether or not the message flashes:

FLASH MESSAGE?

Selecting the FLASH MESSAGE option will cause the message to flash once per second while it is being displayed. After you respond to the FLASH MESSAGE prompt, the DL5 will display a flashing cursor. You can now enter a message.

Default Values for Message Attributes

Entering a Message

All of the message attribut es have def ault va lues. The fi rst time you enter a message into a new DL5, or one whi ch has ha d its memory cleared, the DL5 specifies a default value. From then on, the default values for a new message are the same as the previous message you entered. This feature allows you to quickly enter a number of messages when all of the messages have the same or similar attributes.

After you have specified all the att ri but es for a messa ge, yo u can now enter the actual message. The DL5 stor es messages i n blocks of 16 cha racters . A message may be more than one block in length. The number of blocks that comprise a message is limited only by the amount of memory available. After you have specified a message’s attributes, the DL5 will inform you that a new message can be entered by flashing an asterisk shaped cursor:

Note: You can edit the message being entered, or any previously entered message, by using the edit commands. Chapter 4 describes how to use the edit commands.

You can now ente r you r message . As you ty pe, noti ce that the curs or moves towards the right side of the display as characters a re entered. If the cursor reaches the first character segment on the right, the next character that you enter will posi ti on t he cursor back at the fi r st character segment on the left. For example, a new message is to be entered on a two line DL5 display (16 characters in a block). The DL5 will position the cursor at the first character position on the left:

If the message <Motor Starter #> is entered, the display will appear like this:

MOTOR STARTER #*

If the number <1> is entered at the last character position, the cu rsor will move to the first character segment on t he left . The display will appea r like this:

*OTOR STARTER #1

If you would enter any additional characters, the original characters would be overwritten wit h ne w characters. If you would type in <Allen–Bradley> the message would appear like this:

ALLEN-BRADLEY*#1

If you want to enter a message that is comprised of more than 16 characters (one block) in len gth , you mus t press the [Ctrl] an d [J ] ke ys s imul taneously after the first message block is entered. The DL5 will then move the cursor to the beginning of the next block of text. For example, if you wanted to enter the message “Feed Conveyor Is On” you would need at least two message blocks to enter the message. First you would enter the first part of the message <Feed Conveyor>. The DL5 will display:

FEED CONVEYOR*

You would th en select the next messa ge bl ock by pressing the [Ctr l] and [J] keys. The DL5 will display:

You can now enter the second block of the message <IS ON>. The DL5 will display:

IS ON*

Note: If you press the [Ctrl] and [J] keys simultaneously at the end of a message, a blank message block at the end of the message will be created. The blank message block wi ll be displ ayed for th e specifi ed wait ti me. This can cause apparent delays between messages when the display is in the run mode. Do not type [Ctrl] [J] at the end of a message.

Now when the message is triggered, a two line DL5 will display the message:

FEED CONVEYOR

IS ON

After you have finished entering your message , you can ret urn to the EDI T? prompt in one of two ways:

The DL5 will then display a portion of the message you want to edit. You can now edit the message using the edit commands.

All editing activity occurs at the cursor position. To edit a message, you must first position the cursor at the characters that are to be changed. The following commands are used to position the cursor.

Forespace [Ctrl] [L]

This command moves the cursor one character position to the right. You select the forespace command by pressing the [Ctrl] and [L] keys. If the cursor is already at the last character position, the cursor will move to the first character position on the left side of the display.

Note: Many types of terminals have a forward arrow key. This key will often generate the [Ctrl] [L] command.

Backspace [Ctrl] [H]

This command moves the cursor one character position to the left. You select the backspace command by pressing the [Ctrl] and [H] keys. If the cursor is already at the firs t charact er posi tion in the message th e cursor wil l move to the last character position.

Note: Many types of ter minals have a back arrow or a [BACKSPACE] key. Both of these keys will often generate the [Ctrl] [H] command.

Forward One Message Block [Ctrl] [J]

This command moves the cursor one message block towards the end of the message. If the cursor is al ready at the la st mess age bl ock in a message , th e command will create a new message block directly after the previous message block. You select the forward one message block command by pressing the [Ctrl] and [J] keys.

This command moves the cursor one message block towards the beginning of the message. If the curs or is already a t the first message block in the message, the DL5 will ignore the command. You select the back one message block command by pressing the [Ctrl] and [K] keys.

Deleting a Character

Deleting a Message Block

You can delet e a c haract er by typi ng in a new char acte r dir ectl y ov er t he old character. If you want to delete a character and replace it with a blank space, use th e [SPACE] key.

You can delete an entire message block by pressing the [SPACE] key repeatedly until all of the characters are replaced with blank spaces. However, the message block will not be deleted from memory.

You can delete an entire block of a message by pressing the [Ctrl] and [D] keys. The delete message block command will delete all 16 characters in a message block. After you delete a message blo ck, the DL5 will the n display one of three items:

• If you deleted the first message block in a multiple block message, the DL5 will display the second block of the message.

• If you deleted any mess age block, other than the f ir st message block in a multiple block message, the DL5 will display the previous message block.

• If you deleted the only message block in a single block message, the entire message is deleted and the DL5 will display the EDIT? prompt.

For example, assume that the DL5 contains the following message which is stored in three separate message blocks:

PRESSURE IN

RESERVOIR TANK IS NORMAL

Assume the cursor is positioned at the firs t ch aracter in the second message block. The DL5 display will appear like this:

*ESERVOIR TANK

If the [Ctrl] and [D] keys are now pressed , the messag e block RESERVOIR TANK will be deleted. The messa ge now cont ains j ust t wo message blocks :

PRESSURE IN

IS NORMAL

The DL5 displays the message block that was preceding the deleted message block:

*RESSURE IN

Inserting a Message Block

You can insert a message block (if free message blocks are available) between two previously existing message blocks by pressing the [Ctrl] and [I] keys. The new message block is inserted after the message block that was being displayed when the insert message block command was pressed.

For example, assume that the DL5 contains the fo ll owin g message which is stored in two separate message blocks:

CONVEYOR BELT

HAS STOPPED

Assume that the cursor is positioned at the first character in the first message block. The DL5 display will appear like this:

*ONVEYOR BELT

Note: The cursor does not have to be in the first character position. If the [Ctrl] and [I] keys are now pressed, a new message block will be

created after the first message block. The DL5 will display:

If the message <IN SHIPPING> is entere d in the new message block, the message would now contain three message blocks:

CONVEYOR BELT HAS STOPPEDIN SHIPPING

Deleting an Entire Message

You can quickly delete an entire message from memory by pressing the [Ctrl] and [E] keys. The command will erase all of the message blocks contained in a message.

For example, assume that the DL5 contains the fo ll owin g message which is stored in two message blocks:

HOPPER #2 IS EMPTY

Assume that the cursor is positioned at the first character position in the second message block. The DL5 display will appear like this:

*S EMPTY

If the [Ctrl] and [E] keys are now pressed , the DL5 will first display:

SURE?

Next the [Y] and [Retrn] keys must be pressed to confirm that the message is to be dele ted. The DL5 will delete the message and then displ ay:

EDIT?

With the DIP switch in the Configure position, any serial data is interpreted as a menu or edit command.

2706-UM001A-US-P

Run Mode 5-3

Description of Run Mode

In the run mode, the DL5 wait s for the host to send messag e tr ig gers and/or variable data. The DL5 receives message tri ggers and v ariable d ata throu gh either the parallel or serial port. The serial and parallel ports cannot be active at the same time. The Serial Trigger/Configure DIP switch determines the active port (Serial Trigger position = serial port, Configure position = parallel port). When a message trigger is received, the DL5 searches its memory for the selected message, inserts any imbedded variables, and then displays the message.

If another message trigge r is sent to the DL5 before the fi rst mes sage’s wait time has expired, the DL5 stores the message trigger in a message buffer. The capacity of the message buffer is one message. Refer to the following example which shows how the message buffer operates.

1. The host controller sen ds a message trigger for mes sage number 27 to

the DL5. The DL5 removes the message trigger from the message buffer and displays message number 27.

Using the Serial Port

Chapter 6

Chapter Objectives

The DL5 has a full duplexed RS-232 serial port which is used for:

• communication with the offline programmer and f or programming input from a “dumb” ASCII terminal.

• serial triggering of messages

The operation of the serial port is determined by the Serial Trigger/ Configure DIP switch on the back of the DL5 see page 2-2. The RS-232 serial port is a 9-pin male D-shell connector located at the rear of the DL5. A drawing of the DL5’s connector is provided below:

6-2 Using the Serial Port

RS-232 Signals

The DL5’s RS-232 port uses T ransmit Data sig nal, Receiv e Data s ignal, and Signal Common. The Clear To Send, Data Carrier Detect, and Data Set Ready pins are tied high (+12V) by the DL5, allowing direct connection of the DL5 to terminals or computers requiring a request to send signal. No jumpers at the terminal or computer connector should be required.

Pin Number Signal Name (Signal Mnemonic) Signal Type

1 Data Carrier (DCD) Output 2 Transmit (TXD) Output 3 Receive Data (RXD) Input 4 Data Terminal Ready (DTR) Input 5 Signal Common (COM) -6 Data Set Ready (DSR) Output 7 Request to Send (RTS) Input 8 Clear to Send (CTS) Output 9 Ring Indicator (RI) Output

Data Carrier Detect - Pin 1 Indicates that a continuous frequency

“capable of being modulated or impressed with a signal” is being received. The DL5 sets this line high.

T ransmit Data - Pin 2 Sends out the serialized data fr om the DL5 (e.g., t he serial data is on this pin).

Received Data - Pin 3 This signal also carries serial data. However, the serialized data is sent from another device as input to the DL5.

Data T erminal Ready - Pin 4 Indicates the t ra nsmi ssion device (termina l) is connected, powered up, and r eady t o send data. The DL5 i gnores thi s lin e.

Signal Common - Pin 5 The ground reference for all other signals.

Data Set Ready - Pin 6 Indicates that a communications device is

connected, powered up, and ready for data transmission. The DL5 sets this line high.

Request to Send - Pin 7 Signal from the terminal device requesting the communication device to send data. This typically turns on the data carrier. The DL5 ignores this line.

Clear to Send - Pin 8 This signal indicates to the transmitting device that it can start sending data. The DL5 sets this line hig h.

Ring Indicator - Pin 9 This signal indicates that each device is physically connected to adjacent devices. The DL5 sets this line high.

Using the Serial Port 6-3

Serial Port Protocol

When the DL5 is set to be triggered through the serial port, use the following protocols to trigger messages and display variable data:

Message Trigger [Ctrl][T]

Use the CTRL-T command to trigger messages while the DL5 is in the binary and BCD modes. The message number and address are decimal values. The command has the following format:

CTRL-T

Message

Number

Backslash

where:

– Message Number is a decimal value in the range 1-999 – DL5 Address is a decimal value in the range of 0-127

For example, to trigger Message #123 on a DL5 with an address of 10, the following string would be sent:

ASCII ^T 1 2 3 \ 1 0 ^M HEX 14 31 32 33 5C 31 30 0D

DL5

Address

Carriage

Return

Note: If you need to trigger messages (Round Robin and Numeric modes), with a PLC that does not support unsigned integers, refer to the application note in Appendix D

Note: If the DL5 is in serial trigger mode and you attempt to download messages using the offline programming software, data corresponding to a message trigger command will be executed.

2706-UM001A-US-P

6-4 Using the Serial Port

Variable Data [CTRL][V]

Use the CTRL-V command to send data for display in Binary, BCD, Numeric, Priority, and Round Robin modes. All values are decimal values. The command has the following format :

CTRL-V

Variable

Data

Backslash

Variable

Position

where:

– Variable Data is 1 to 5 ASCII digits (0-65535) – Variable Position is single ASCII digit (value is ignored) – DL5 Address is 1 to 3 ASCII digits (0-127)

For example, to send a value of 500 to a DL5 with an address of 99, the following string would be sent:

ASCII ^V500\1\99^M HEX 16 35 30 30 5C 31 5C 39 39 0D

Backslash

DL5

Chapter Objectives

Description of the Parallel Port

This chapter provides:

• A description of the parallel port.

• Data format requirements for parallel input.

• Descriptions and examples of message triggering.

• Parallel port interface examples.

Note: This chapter describes how you can use the parallel port to trigger messages. If you requ ire i nformat ion on ho w to inpu t va riabl e data , refe r to Chapter 9.

ATTENTION: The DL5 only has single direction communications (receives data, cannot send data). Do not use the DL5 for critical display applications. Single direction communications does not provide verification that messages sent by the control s yst em have be en rec eived a nd dis played by the DL5.

You can use the parallel port of the DL5 to trigger messages and to input variable data. The parallel port is located on the back of the DL5. The parallel port terminals (TB1) are labeled as shown on the next page.

Using the Parallel Port 7-3

Selecting BCD or Binary Data Format

The parallel port will accept data and message triggers in either a binary or Binary Coded Decimal (BCD) format or in non-coded discrete form which allows the DL5 to easily replace pilot lights as described in Chap ter 10.

Each numbering system, binary or BCD, has its own merits. Your choice will often be based upon the format used by your controller. Both the binary and BCD numbering systems allow you to address all 999 possible message numbers but vastly different maximum variable values. The maximum variable value that can be input in binary or BCD run modes is shown below:

Run Mode Maximum Message # Maximum Variable Value

BCD 999 3,999

Binary 999 16,383

You must select which format best suits your needs and then select the run mode as described in Chapter 8.

2706-UM001A-US-P

7-4 Using the Parallel Port

Using Binary Data Input

In the binary (Run) mode, the DL5 interprets data on terminals D0 through D13 as binary data. Terminals D14 and D15 are the strobe lines. Terminal D0 represents the least significant digit and D13 represents the most significant digit . A data line may eith er be at ground leve l, which represent s a binary value of 0, or a data line may have a voltage present, which represents a binary value of 1.

The convention of having a voltage represent a value of 1 and ground representing a value of 0, is known as positive binary logic (high tr ue logic). The opposite conventi on is known as n egative binary l ogic (lo w true lo gic). You can set the DL5 to accept eit her positive or negative logic (high or lo w true), refer to Chapter 8. The following table shows the value of each data line. Selecting the binary data run mode is explained in Chapter 8.

Binary Values of the Data Lines

Data Line Value When On

(True)

D0 1 D8 256 D1 2 D9 512 D2 4 D10 1,024 D3 8 D11 2,048

Data Line Value When On

(True)

D4 16 D12 4,096 D5 32 D13 8,192 D6 64 D14 Strobe Line D7 128 D15 Strobe Line

The table below shows the control functions of the strobe lines:

D14 D15 Function

High or Low High Indicates that binary value on D0 through D13 represents a

message number.

High Low Indicates that binary value on D0 through D13 represents

variable (numeric) data.

Low Low Binary value on D0 through D13 is ignored.

Example: Assume that the following logic lev el s (posit ive log ic) appe ar on the data lin es.

Data Line: D0 D1 D2 D3 D4 D5 D6 D7 D8 D9 D10 D11 D12 D13 D14 D15 Logic Level: 1000100100001010 Value: 1000160012800004,096 0 0 0

2706-UM001A-US-P

Adding the values of the individual data lines provides the value being entered, in this example 4,241. Since strobe line D14 is high (voltage present) and D15 is low (ground level), this value is interpreted as variable data.

Using the Parallel Port 7-5

Using BCD Data Input

The fourteen data lines can also be used to input BCD formatted data. The BCD numbering system use s a gr oup of four data li nes to represent a sin gle decimal digit. The t able below sh ows t he valu e of ea ch data line. Sel ecti ng the BCD run mode is explained in Chapter 8.

Data Line Value When On

(True)

Control functions of the strobe lines are the same for BCD data input as for binary data input.

For example, assume the following logic (positive logic) levels appear on the data lin es.

Data Line: D0 D1 D2 D3 D4 D5 D6 D7 D8 D9 D10 D11 D12 D13 D14 D15 Logic Level: 1010001010001010 Value: 1040004001000001,000 0 0 0

Adding the values of the individual data lines provides the value being entered, in this example 1,145. Again, D14 is high (voltage present) and D15 is low (ground level), so this number is interpreted as variable data.

2706-UM001A-US-P

7-6 Using the Parallel Port

Logic Levels

The DL5’s parallel port accepts DC inputs of 0-24 volts. These input voltages can be used to t rigger messages or transf er variab le (numeric) data. The DL5 interprets the voltages that are pres ent on the data lines as either a “High” or “Low” condition. There is also a third state which should be avoided, an in between or indeterminate state. The indeterminate state occurs when the input voltage is between the “High” voltage range and the

“Low” voltage range. The voltage ranges that the DL5 interprets as either “High” or “Low” values depends on whether positive or negative binary

logic has been selected.

The table below lists the voltage ranges and their logic values.

Positive Logic Level

High (True) Low (True) 3.5 to 24V DC 0.9 to 3.5V DC Low (False0 High (False) 0 to 0.9V DC 0.9 to 3.5V DC

Using the Parallel Port 7-7

Using the Numeric (Run) Mode

In this mode, the DL5 interprets inputs into the parallel port only as BCD numeric data and immedi ately dis plays the BCD nu mber. Only line 1 of the DL5 is used. Inputs to the first twelve terminals (D0 through D11) are always interpreted as three BCD digits. Inputs to the last four terminals (D12 through D15) are interpreted as a fourth BCD digit (if the input is a valid BCD code), or as a special instruction code (if the input is not a valid BCD code). The speci al i nstruction code all ows you to define a desti nat ion on the DL5 display for the three BCD numbers on data lines D0 through D11. This allows a number as large as 15 digits, two 6 digit numbers, or three 3-digit numbers to be displayed on the DL5. The table below defines the special instruction codes of D12 through D15.

7-8 Using the Parallel Port

Example:

You want to display the following number and decimal point in the DL5:

456123

You would send data to the parallel port in the following sequence:

D15 D14 D13 D12 D11 D10 D9 D8 D7 D6 D5 D4 D3 D2 D1 D0

1 1 1 1 0 0 0 0 0 0 0 0 0 1 1 0

Clears the display and sets the decimal point.

And positions the decimal point 6 places from the right of the display.

D15 D14 D13 D12 D11 D10 D9 D8 D7 D6 D5 D4 D3 D2 D1 D0

1 1 0 0 0 0 0 1 0 0 1 0 0 0 1 1

Directs BCD digits to third 3 character position.

And sends the BCD number 123

D15 D14 D13 D12 D11 D10 D9 D8 D7 D6 D5 D4 D3 D2 D1 D0

1 1 0 1 0 1 0 0 0 1 0 1 0 1 1 0

Directs BCD digits to fourth 3 character position.

And sends the BCD number 456

If an invalid BCD digit i s re ceived, the correspondin g character position on the display will be blan k. If the number s etting th e decimal poi nt is zero, no decimal point is displayed. When the decimal point is used, it takes one character position on the display as shown in the examples.

You can update the numbers on the display without clearing the display or resetting all digits. That is, to change three digits of a number, you send only those three digits, along with the appropriate special instruction code; the remaining digits are left unchanged.

2706-UM001A-US-P

Note: If you are changing all the numbers on the display, you should clear the entire di splay.

Using the Parallel Port 7-9

Example:

You want to change the number in the previous example from 123.456 to

123.789999:

789123 999

You would send data to the parallel port in the following sequence:

D15 D14 D13 D12 D11 D10 D9 D8 D7 D6 D5 D4 D3 D2 D1 D0

1 1 0 1 0 1 1 1 1 0 0 0 1 0 0 1

Directs BCD digits to overwrite the fourth 3

character position.

And sends the BCD number 789.

D15 D14 D13 D12 D11 D10 D9 D8 D7 D6 D5 D4 D3 D2 D1 D0

1 1 0 0 1 0 0 1 1 0 0 1 1 0 0 1

Directs BCD digits to third 3 character position.

And sends the BCD number 999.

Note: No leading zero blanking is performed in the numeric mode. however , individu al digit s for D0 t hrough D1 1 can be bla nked by setting the input for that digit to a non-BCD value (greater than 9).

7-10 Using the Parallel Port

Numeric Mode and Autorun Message

Using a two line DL5 , the numer ic mode can display an autoru n message o n line two in addition to the numeric data on line one. The autorun message is selected as described in Chapter 8. It should be programmed to appear on line two with autoclear set to NO. Each time the display enters the run mode or is powered up, the autorun message will appear on line two. The numeric data being sent will appear on line one.

Example:

7231

568 9

PRES

ETEM

This autorun message serves as a “legend” or “label” for the numeric variables.

When using the numeric mode, data must be held on the parallel port for 110 milliseconds (see page 7-13).

2706-UM001A-US-P

Using the Parallel Port 7-11

Using DC Outputs to Trigger the DL5

There are two types of DC outputs:

• Hard contact outputs

Hard contact outputs contain mechanically operated contacts. Examples of hard contact outputs include relays, push buttons, limit switches, and contact output modules such as Allen-Bradley’s PLC module (Catalog No. 1771-OW) or SLC module (Catal og No. 1746- OW16). Any cont act that does not have a leakage current while in the OFF state can be considered a hard contact device.

• Solid-state DC outputs

Solid-state outputs do no t ha ve any mechanically operate d cont ac ts . All switching functions in a solid-state contact are done electronically. Examples are:

PLC Modules – Catalog No. 1771-OB or -OBD

SLC Modules

– Catalog No. 1746-OV8, -OV16, -OV32

Determining Current Requirements For DC Outputs

Y o u must check to make sur e that the DC outputs sup plying the pa rallel port can supply enough current to handle the requirements of the DL5’s parallel port. The table below lists the current requirements for one DL5 parallel port input.

Parallel Port Typical Requirements for DC Outputs

5V DC Input 12V DC Input 24V DC Input

3.0 mA 7.3 mA 14.6 mA

T o determine the total current requirements of the parallel port, multiply the number of inputs being used by the value found in the above table. For example: Assume that you are using 24 VDC outputs:

Each input will draw a peak current of 14.6 milliamperes. If you are using all sixteen inputs, your output source must be able to provide 234 milliamperes of current (16 x 14.6 mA = 234 mA).

The table below lists the voltage and current requirements, per DL5 input, for various Allen-Bradley output devices.

Parallel Port Power Supply Requirements

Timing Requirements of the Parallel Port

The DL5 parallel ports require an input voltage source between 5-24 VDC with peak-to-peak noise and ripple less than 5% of the input voltage.

A TTENTION: To avoid ground loops, the same power supply that powers the displ ay mus t be use d to supply the parallel por t.

The DL5 reads (scans) the data lines periodically . You must ensure that the data is present on the data lines long enough to be read.

Note: Refer to Chapter 9 for a description of the timing requirements for messages with variable data.

In order to ensure that the data is rea d, the data must remain on the data lines for at l eas t 110 milliseconds. After eac h scan the DL5 saves a copy of the data that was read. If the next scan reads the same data, the data is ignored. This feature prevents multiple triggering of the same message.

The figure below illustrates a typical message trigger sequence. Message #1 is triggered and then message #10 is trigger ed. In this ex ample, th e DL5 is set to accept BCD formatted codes (message or variable).

The following are descriptions of what occurs during each of the four timing intervals (t0, t1, t2, and t3):

During t0, the trigger for message No. 1 and strobe line D15 to indicate message number are placed on the data lines.

During t1, the message trigger and strobe are kept unchange d a t the parallel port for a minimum of 110 milliseconds.

During t2, the trigger for message No. 10 and strobe line D15 to indicate message number are placed on the data lines, and the trigger for message number 1 is removed.

During t3, the message trigger and strobe are kept unchange d a t th e parallel port for 110 milliseconds.

2706-UM001A-US-P

8-4 Special Functions

SET PORT Special Function

The set port function allows you to set the fo ll owing parallel and serial port parameters.

• positive or negative logic (high true or low true) of the parallel port

• baud rate (300, 1200, or 9600) of the RS-232 serial port

• address of the DL5 (for serial triggering)

You enter the set port function by pressing the [Y] and [Retrn] keys in response to the SET PORT? prompt. After selecting the set port function, the first prompt that the DL5 displays:

HIGH TRUE?Y

If you answer [Y] (the default) to the high true input option, the DL5 will interpret the voltages on the data lines as positive logic signals. If you answer [N] to the high true option, negative logic is selected.

If positive logic is selected:

• A voltage on a data li ne is interpreted as an ON ( lo gic 1 / true) conditi on.

• The absence of voltage on a data line is interpreted as an OFF (logic 0 /

false) condition.

If negative logic is select ed:

• A voltage on a data line is interpreted as an OFF (logic 0 / false) condition.

• The absence of voltage on a data line is interpreted as an ON (logic 1 / true) condition.

Note: If possible, we recommend that you confi gure your system so tha t in a normal operating condition as few as possible input lines have a voltage applied to them. This will keep the DL5 at a lower operating temperature and extend its life.

The next prompt that you must respond to is:

Baud (3, 12, 96):96

The present baud ra te is t he defaul t valu e. Enter t he desir ed baud rat e: 3 for 300, 12 for 1200, and 96 for 9600. The baud rate changes immediately. The DL5 is shipped with a baud rate of 9600 baud.

Once the baud rate is changed, the baud rate of your programming device must also be changed to match the DL5 before programming/editing of the DL5 can continue. After specifying a baud rate, the current address is displayed:

ADDRESS: xxx

2706-UM001A-US-P

Special Functions 8-5

After you provide an address, press [Retrn] and the DL5 will display the beginning RUN? prompt.

Run Mode Special Functions

The run mode determines how the DL5 will interpret the data present on the parallel port. The DL5 is shipped in the numeric mode.

SET RUN MODE?N

To change or view the run mode selection, respond to the SET RUN MODE? prompt by pressing [ Y], the n [R etrn] .The fo llowin g ap pears on the display:

RUN MODE=xx

Where xx is the mnemonic for the last entered run mode.

Respond to the RUN MODE = prompt with a two letter mnemonic. The mnemonic that you pro vid e dete rmines whic h Run Mod e is u sed. The ta ble below lists the run modes of the DL5’s parallel port. After you provide a run mode mnemonic the DL5 will return to the RUN? prompt. Once a run mode is selected, the DL5 will ente r that run mode on default when power is cycled off, then on. If an invalid mnemonic is entered, the previously selected run mode mnemonic is displayed.

8-6 Special Functions

Debug Special Function

The Debug special function is very valuable if you are having difficulty triggering messages properly in the run mode. The debug function allows you to visually determine whether or not a voltage is applied to a DL5 data line. If you respond to the DEBUG? prompt by pre ssing the [ Y] and [ Retrn] keys, the DL5 displays the status of the data lines:

0000010000010011

The debug mode display consists of sixteen characters (ones and zeros). This display represents the condition of the sixteen data lines. The character on the far left represents data line D15 and the character on the right represents data line D0. If you have set the parallel port for negative logic, a voltage on a d at a l ine will be represented by a 0. If posi ti ve logic is selected, a voltage on a data line will be represented by a 1. For example, assume that a debug mode display appears like this:

0000100001100100

If positive logic has been selected, the above display would indicate that there is a voltage present on data lines D2, D5, D6, and D11. If negative logic has been selected, the above display would indicate that there is a voltage present on data lines D0, D1, D3, D4, D7, D8, D9,D10, D12, D13, D14, and D15.

To exit the debug mode, press the [Esc] key three times.

2706-UM001A-US-P

Special Functions 8-7

CLEAR MEMORY Special Function

The clear memory special function clears all messages from the DL5 EEPROM memory. To clear the DL5 memory perform the following steps:

1. Press the [Y] and [Retrn] keys in response to the CLEAR MEMORY?

prompt. The DL5 displays:

SURE?N

2. Press the [Y] and [Retrn] keys in response to the SURE? prompt. The

DL5 displays:

POSITIVE?N

3. Press the [Y] and [Retrn] keys in response to the POSITIVE? prompt.

The DL5 displays:

MEMORY LOST

While Memory Lost is displayed, the DL5 is actually clearing the EEPROM. Hitting any key, such as [Escape], will not speed up this function. Depending on the amount of t he memory used and the size of the EEPROM (2 or 8 Kbytes), it could take up to 30 seconds before Memory Lost is cleared and the display shows:

SET AUTORUN Special Function

RUN?

The set autorun function allows you to set the autorun message number. If the power to the DL5 is interrupted while in the run mode, the DL5 will automatically enter the run mode when the power is reapplied. The autorun message is the firs t mes sa g e t hat th e DL5 displays when the DL5 enter s t he run mode. After the autorun message is display ed the DL5 resumes normal run mode operation. If you pr ess the [ Y] and [Ret rn] k eys in re sponse to the SET AUTORUN? prompt, the DL5 displays:

NUMBER: X

Note: X is the value of the last message number edited.

You can now enter the message number of the message that you want displayed when the DL5 is powered up in the autorun mode. Enter the autorun message number (0–999) and then press the [ Retrn] key. If no autorun message is desired, enter a 0 (zero). After entering an autorun message number, the DL5 displays the RUN? prompt.

Chapter 9

Chapter Objectives

Variable Data Limits

In this chapter you will learn how to insert up to five digits of variable data in a message. You will learn:

• how to program messages with embedded variables.

• the format of the variable data.

• timing requirements for the transfer of variable data.

The DL5 can accept message triggers and variable data using either the parallel or serial port.

Serial Port - The serial port accepts CTRL-T commands for message triggers an d CTRL-V commands for va riable data. T he range for variable data sent to the serial port is (0-65535). Serial commands always use decimal numeric values (binary and BCD distinctions do not apply).

Parallel Port - The parallel port can be set to accept either binary or BCD formatted data for message triggers and variable data input.

Whichever format (BCD or binary) you select will be used for both the variable data and message triggers. You cannot input message triggers in one format and variable data in another format. The table below shows the largest varia ble and me ssage number that can b e entered for both bi nary and BCD formats.

9-2 Using the Variable Data Feature

Creating Messages with Embedded Variable Data

You can progra m variable data within a messa ge while the messa ge is being created in the edit mode. To embed one digit of a variable, press the [Ctrl] key and [V] keys simultaneously at the location in the message where the variable digit is to appear. The [C tr l] and [V] command will i nse rt a caret ^ in the message. For example: Assume that the following message is being entered:

7+(&2817,6

To embed a single digit of a variable, press the [Ctrl] and [V] keys. The DL5 will display the location of the variable in the message:

7+(&2817,6A

Up to five single digit variables (only four variables allowed with BCD format) can be embedded in a message. The embedded variables do not have to be in consecutive positions in a message. For example: The following message has been entered, the DL5 is set to accept BCD formatted data:

AA2)AA%$'

If the number 1050 is transferred to the DL5 and the message is triggered, the DL5 will display:

2)%$'

2706-UM001A-US-P

Using the Variable Data Feature 9-3

Embedding a Decimal Point

You can display numbers which have decimal points. The decimal point is inserted just li ke any oth er char acter and it t akes up one full ch ara cter space. Insert a decimal point before or after the [CTRL] [V] by typing [.]. For example, the following steps would be required to create the message “SPEED IS . FPS”.

1. Enter the following message:

63((',6

2. Enter the first variable digit by pressing the [Ctrl] and [V] keys:

3. Press the [.] key to ente r the decim al point . Notice that the decimal point

requires a character position. The decimal point becomes a part of the variable.

4. Then enter the second variable digit by pressing [Ctrl] and [V] keys.

5. Finish entering the message by typing [F] [P] [S].

Note: Use [CTRL][X] to imbed variable digits with leading zeros.

[CTRL][V] imbeds variable digits without leading zeros.

Sending Variable Data Through the Serial Port

Use the CTRL-V command to send data for display in Binary, BCD, Numeric, Priority, and Round Robin modes. All values are decimal values. The command has the following format :

CTRL-V

Variable

Data

Backslash

Variable Position

Backslash

DL5

Address

Carriage

Return

where:

– Variable Data is 1 to 5 ASCII digits (0-65535) – Variable Position is single ASCII digit (value is ignored) – DL5 Address is 1 to 3 ASCII digits (0-127)

For example, to send a value of 500 to a DL5 with an address of 99, the following string would be sent:

ASCII ^V500\1\99^M HEX 10 35 30 30 5C 31 5C 39 39 0D

Note: In Binary mode, variable data can be in the range 0 to 16,383. In BCD mode, variable data must be in the range 0 to 3999. In Round Robin. Priority and Numeric modes, variable data can be in the range of 0 to

65535.

Note: The CTRL-V command in Priority, Round Robin and Numeric modes triggers messages not variables.

9-4 Using the Variable Data Feature

Parallel Port Strobe and Data Bits

The DL5 uses the sixt een data lin es (D0 thr ough D15) to input b oth varia ble data and message t ri gge rs . Data lines D0 thro ugh D13 t ra nsf er the fourteen data bits and data lines D14 and D15 are the two strobe lines.

The strobe lines indicate whether the data on the data lines is a message number or variable data. There are four possible combinations of the two strobe lines. The table below lists the four strobe combinations and the DL5’s interpretation of the strobe commands.

Strobe Commands

Strobe Command Strobe Line, Data Line D14 Strobe Line, Data Line D15

Ignore Data Lines OFF OFF

Variable Data ON OFF Message Number OFF ON Message Number ON ON

Notice that if data line D15 is ON, the DL5 will interpre t the data on the data lines as a message number r egardl ess of the condit ion of data li ne D14.

Using the Variable Data Feature 9-5

Parallel Port Timing Requirements

The following is an example of how the strobe commands are used. In this example, message #12 , which contains a two digit variable, is triggered. The message that was entered for message #12 appears like this:

63((',6AA)36

First the controller sends the variable value (BCD format) for message #12 to the DL5. Then the controller sends the trigger for message #12. The figure below illustrates the timing of th e data transfer and message trigger.

BCD Message Number Timing Example

D4 D5 D6 D7

D8 D9

D10 D11

D12 D13 D14 D15

The following describes what occurs during each of the timing intervals.

t0- During t0 the variable dat a 35 and strob e line D14 to in dic ate var iable

data is set on the data lines.

t1- During t1 the value of 35 and strobe line D14 are maintained for 110

milliseconds.

t2- During t2 the message number 12 is placed on the data lines, and

D15 is set to indicate a message number. D14 is reset.

t3- During t3 the message number 12 and strobe line D15 are main tai ned

for 110 milli sec onds.

The timing example (previous page) shows the minimum hold time (110

milliseconds) that is required for each step of the variable data transfer and message trigger.

2706-UM001A-US-P

9-6 Using the Variable Data Feature

Note: The PLC program scan time must be added to the hold time. If the scan time is 10 milliseconds, then the minimum data hold time in the PLC program should be 120 milliseconds to make sure data is held at the DL5 for the minimum 110 milliseconds.

To summarize the timing requirements:

• Data and strobes are set all at once.

• Once data and strobe lines are set, they must remain unchanged for a

minimum of 110 milliseconds.

• The total cycle time for a variable dat a transfer and message trigger is a minimum of 220 milliseconds. A cycle time of 220 millise cond s all ows you to update a variable approximately 4 times per second.

2706-UM001A-US-P

Using the Variable Data Feature 9-7

Suggestions on Using the Variable Data Feature

Message attribute settings are important to the proper functioning of the variable da ta feature. Refer to Chapte r 3 for review of message attributes. The following message attribute settings are recommended.

Line Selection recommendations:

• Do not use the scroll mode when variables are within a message. The message should appear as one or two lines.

• Limit each message to one screen (16 characters if a one line message, 32 characters if a two lin e message).

Wait Time recommendation:

• Set the wait time of a variable message to zero to allow for the fastest update of the variable.

Auto Clear recommendation:

• Set auto clear to NO.

Auto Repeat recommendation:

• Do not use the auto repeat display option for messages that contain variable data. If the auto repeat display option is selected, the DL5 will resample the data lines for variable data each time the specified message wait time has expired.

Your controller cannot send variable data for a new message trigger until the auto repeat message is halted. Y ou can halt the display of an auto repeat message by triggering a programmed blank message number.

Note: A blank message is one which has been created but has no displayable characters. Its attributes could be Wait Time Zero, Auto Clear No, and Auto Repeat No.

For example, the following describes a triggering sequence that occurs using an auto repeat message with four variable digits. The message being triggered is:

AA2)AA%$'

This message has a wait time of zero, and no auto clear.

1. First, the controller sends the variable data “1050”.

2. Next, the controller sends the trigger for the message.

2706-UM001A-US-P

9-8 Using the Variable Data Feature

3. The DL5 wi ll then display the message:

2)%$'

4. The controller then transmits a new variable “2040”.

5. The DL5 wi ll then display the message with the new variable data:

2)%$'

6. To enter and display a different message with embedded variable data,

the controller must first trigger a programmed blank message to stop display of the variable message.

7. The controller can now send the variable for the new message.

8. The controller can then send the message number for the new message

Updating a Variable Frequently – If your application requires that the

variable data within a message be updated frequently, you should program the message with the following attributes:

• A wait time of zero.

• The auto clear function is not selected.

These message attribute settings will make it possible to update variable data at the fastest rate (once every 220 milliseconds). This assumes a normal sequence of events to enter variables and message numbers:

• Send a variable. (110 milliseconds)

• Send a message number. (110 milliseconds)

• Send a variable. (110 milliseconds)

• Send a message number, etc. (110 milliseconds)

Note: PLC program scan time must be added to the 110 millisecond data hold time in the PLC program to assure that data i s on the DL5 parallel po rt for 110 milli sec onds.

Using the DL5 Parallel Port to Replace Pilot Lights

Chapter Objectives

Description of Input Modes

This chapter shows you how to replace up to 16 pilot lights with a single DL5. Descriptions of both the prior ity and rou nd robin ope rating modes ar e provided.

The DL5 has 2 modes of operation which allow you to replace pilot lights:

• Round Robin input mode - while in the round robi n mode of operati on, the DL5 will look at the sixteen data lines as individual inputs. Each of the inputs is like the input wire to an individual pilot light. When a data line to the DL5 is triggered, a message corresponding to that data line is displayed.

• Priority input mode - the priority input mode is similar to the round robin input mode except that each of the data lines is assigned a priority in relation to the other data lines.

Note: These pilot li ght opera ting modes do not s upport va riable da ta withi n a message.

Pilot lights are typically used in one of two ways:

1. Pilot lights can be used as status indicators. For example, a pilot light can inform an operator that a motor is on or off.

2. Pilot lights can also be used as diagnostic indicators. For example, a pilot light can inform an o perator that an overload relay is tripped.

2706-UM001A-US-P

10-2 Using the DL5 Parallel Port to Replace Pilot Lights

Round Robin Mode

In the Round Robin mode of operation you can specify both an OFF state message and an ON state message for each input. Messages are scanned in sequence beginning with data line D0 and ending with data line D15. If several inputs are ON, the DL5 displays the messages in the sequence that they are scanned. The following table lists the message numbers that are assigned to each of the sixteen inputs.

Data Line No. ON Message No. OFF Message No.

D0 1 17 D1 2 18 D2 3 19 D3 4 20 D4 5 21 D5 6 22 D6 7 23 D7 8 24 D8 9 25 D9 10 26 D10 11 27 D11 12 28 D12 13 29 D13 14 30 D14 15 31 D15 16 32

Notice that each of the sixteen data lines listed in the table has both an ON message number and an OFF message nu mber assigned. You do not have to program both an OFF and an ON message for ea ch input . You can program only an ON or only an OFF state message; or no message at all.

2706-UM001A-US-P

Using the DL5 Parallel Port to Replace Pilot Lights 10-3

When the DL5 is placed in the round robin mode of operation, the DL5 begins by looking at the first data line D0. One of three events will occur depending upon the con dition of the data line and whether or not a message is programmed:

• If data line D0 is in an ON state, the DL 5 will display message #1 (if message #1 is programmed). Message #1 is the ON state message for data line D0.

• If data line D0 is in the OFF state, the DL5 will display message #17 (if message #17 is programmed ). Message #17 is the OFF state message f or data line D0.

• If no message exists, the DL5 will ignore data line D0.

The DL5, will then look at the second data line, D1. One of three ev ents will occur dependin g upon the condition of the dat a l ine and whe th er or not a message is programmed.

• If data line D1 is in an ON state, the DL 5 will display message #2 (if message #2 is programmed). Message #2 is the ON state message for data line D1.

• If data line D1 is in the OFF state, the DL5 will display message #18 (if message #18 is programmed ). Message #18 is the OFF state message f or data line D1.

• If no message exists, the DL5 ignores data line D1.

The DL5 then looks at the remainder of the data lines, D2 through D15. After data line D15 is scanned, the DL5 will then start the sequence over again beginning with data line D0. If only one data line is on, the display will not clear befor e retrig gering the message a ssociated wi th that dat a line. If no data lines are on , the dis play i s clea red after the mess age wait time ha s expired.

Note: If a data line is turned ON then OFF before the DL5 scans it, it will not be remembered as being ON by the DL5. The DL5 will not look for additional ON terminals until it is done executing a message it has recognized as ON.

2706-UM001A-US-P

10-4 Using the DL5 Parallel Port to Replace Pilot Lights

Priority Mode

In the priority mode of opera tion you can only spe cify an ON state me ssage for each input. If several inputs are ON, only the highest priority message will be displayed. The following table lists the message numbers that are assigned to each of the sixteen inputs.

Data Line No. ON Message No. OFF Message No.

D0 1 1 (Highest) D1 2 2 D2 3 3 D3 4 4 D4 5 5 D5 6 6 D6 7 7 D7 8 8 D8 9 9 D9 10 10 D10 11 11 D11 12 12 D12 13 13 D13 14 14 D14 15 15 D15 16 16 (Lowest)

If programmed, message #17 is displayed if no data lines are ON.

Notice that each of the sixteen data lines listed in the table above only has an ON message number assigned. You do not have to program a message for each of the inputs; if an in put does not have a messag e prog rammed , the DL5 will ignore the input. Each input has an assigned priority level. Data line D0 has priority over data line D1, data line D1 has priority over data line D2, data line D3 has priority over data line D4, etc. The DL5 displays the message number that corresponds to the highest priority data line. For example: If data lines D1, D4, and D7 are in an ON condit ion, the DL5 will display message #2 (message #2 is the message assigned to data line D1). Message #2 will continue to be repeated for as long as data li ne D1 rema ins in an ON state; unless da ta line D0 changes to an ON state. If data line D0 changes to an ON state , it ove rr ides data line D1 because dat a l ine D0 has a higher priority. The DL5 then displays message #1 (message #1 is the message assigned to data line D0). If only one input is ON and that input goes OFF, the display will automatically clear.

2706-UM001A-US-P

In addition to the sixteen messages associated with data lines D0 through D15, there is a message #17. Message #17 is only displayed when none of the data lines is in an ON condition.

Using the Round Robin Input Mode

If you want to operate the DL5 in the Round Robin mode of operation, perform the following steps:

1. You must decide whether the DL5 will be set for positive or negative logic. If positive logic is selected, voltage on a data line will represent an ON condition. If negative logic is selected, the absence of voltage on a data line represents an ON condition.

2. Select the round robin mode of operation as described in Chapter 8

3. Place the DL5 in the edit mode and program messages for the message

numbers that are associated with each input. The following message attribute settings are suggested to provide the clearest round robin functionality.

– Line 1, line 2, or both lines can be selected as desired.

– Scroll message can be selected as desired.

– Wait time can be set as desired and will control how long a message is

displayed before the DL5 goes on to the next message.

– Select Auto Clear, to clear the screen after each message. Otherwise

you might have a portion of a two line message remaini ng on the DL5 when a sing le line message follows.

Note: The DL5 will always clear the display when no inputs are on.

– Auto Repeat has no function in Round Robin mode.

– Flash Message can be selected as desired.

4. Place the DL5 in run mode.

In Priority Input mode, only one message (the highest priority) can be on the screen at a time.

If you want to operate the DL5 in priority mode, follow these steps:

1. You must decide whether the DL5 will be set for positive or negative

logic. If positive logic is selected, voltage on a data line will represent an ON condition. If negative logic is selected, the absence of voltage on a data line repres ents an ON c ondition. Ch apter 8 d escribes how you can set the DL5 for either positive or negative logic.

2. Select the round robin mode of operation as described in Chapter 8.

3. Place the DL5 in the edit mode and program messages for the message

Using the DL5 to Replace BCD Displays and Lookup Tables

Chapter Objectives

Replacing a BCD Fault Code Display

This chapter provides instructions on how to replace a 2 or 3-digit BCD numeric display and any associated lookup tables with a single DL5.

The first step in replacing a BCD display is to determine if your DL5 has enough memory to store all of the BCD codes. Typically a BCD display is used in conjunction with a lookup table. If a code is displayed on the BCD display, an opera to r will refer to a lookup table to determ ine t he meaning of the code. If you are going to replace a BCD display and lookup table with a DL5 you must make sure that the DL5 can store the meanings of all the codes listed in the BCD lo okup tabl e. The DL5 can st ore 94 or 387 mess age blocks depending on memory size (2K or 8K).

Note: Memory capacity is given in the number of message blocks that are available. Some of the messages that you enter may require more than one message block. A message block is one line of 16 characters.

After you have determined that the DL5 has sufficient capacity to store the messages, perform the following steps:

1. You must set the DL5 to accept positive logic. If positive logic is selected, voltage on a data line will represent an ON condition.

2. Set the DL5 to accept BCD input as described in Chapter 8.

3. Place the DL5 in the edit mode and program messages for the message

numbers that were previously displayed on the BCD display.

4. Tie strobe line D15 high to indicate message numbers by wiring it to a 5-24 VDC source.

5. Place the DL5 in the run mode.

Grounding

Wire Routing

In this chapter you will learn how to:

• Mount the DL5 in a panel or an enclosure.

• How to wire the DL5 to your control system.

Grounding is an important safety mea sure in in stallin g the DL5. As with all solid-state systems, grounding also helps limit the effect of noise due to electromagnetic interference (EMI). The DL5 mounting studs and nuts (once tightened) connect the DL5 chassis to your equipment ground.

Note: The common terminal on the back of the DL5 is not equipment ground. The common te rminal must be c onnect ed sepa rate ly t o your power supply common.

Careful wire routing helps reduce electrical noise. Route all DL5 wiring separately and away from all high voltage wiring (115VAC or above). Do not run the DL5 wiring in the same conduit as any AC power wiring (115 VAC and above). When high voltage wiring and the DL5 wiring must cross, their intersection should be perpendicular. In addition, the data line wiring (D0-D15) should be routed away from transformers, solenoids, or other devices that are known to generate electrical noise (EMI).

ATTENTION: Fusing the DL5 power wiring is import ant to protect both the power supply and the DL5 from damage should a short circuit occur. Since the DL5 has no fuses, we recommend you use external fusing.

ATTENTION: You must connect the common lead of the power source to the DL5. Failure to connect the common lead may result in electrical shock. In addition, the common lead protects the DL5 from electrical noise. Do not apply power to the display until all wiring to the DL5 is completed.

ATTENTION: To avoid ground loops and damage to the

equipment, the same p ower suppl y must be us ed for t he parall el port and the power input to the DL5.

Mounting the DL5

You can mount the DL5 in a custom panel or enclosure.

When the DL5 is properly installed, the faceplate of the DL5 provides a NEMA Type 12/13 and 4 enclosure integrity rating. To mount the DL5:

1. Punch and drill the appropriat e mounting hole s in the encl osure or pan el.

The following page shows the mounting dimensions of the DL5.

ATTENTION: DO NOT install the DL5 until all cutouts and holes are completed. Metal filings may fall into and damage the DL5.

2. Remove the four nuts from the mounting studs on the DL5’s face plate.

3. Install the display in the panel cutout and tighten the four nuts on the

mounting studs to a torque of 9 lb-in (1.02Nm).
