Summary of Changes
This document describes the InView Marquee Message Display.
Revision bars in the margin identify updated information. Changes for
this version of the document include:
ChangePage
Updated information on how to change the serial address1-2
Added information about how to use the 2706-PCABLE1 to
download a message application
Added information about the communication module when
you set the IP address.
These instructions show how to change the serial address and how to
mount InView series signs with NEMA Types 4, 4X, and 12 enclosures.
These signs are intended for indoor use only. Type 4 enclosures are
intended to provide a degree of protection against windblown dust
and rain, splashing water, and hose-directed water. Type 4X
enclosures are intended to provide a degree of protection against
corrosion, windblown dust and rain, splashing water, and
hose-directed water. Type 12 enclosures are in a sealed case that is,
dust free, gasketing, and spray down resistant.
Install the InView display conforming to NFPA 70E, Electrical Safety
Requirements for Employee Workplaces. In addition to the NFPA
general guidelines, refer to the following.
• Careful cable routing helps minimize electrical noise. Route
incoming power to the module by a separate path from the
communication cables.
TIP
Do not run communications wiring and power
wiring in the same conduit!
• Where communication and wire paths must cross, make their
intersection perpendicular.
• Grounding helps limit the effects of noise due to
electromagnetic interference (EMI). To avoid problems caused
by EMI, properly ground all equipment and use shielded cables.

Change the Serial Address
Checkout Procedure
IMPORTANT
A serial address for an InView sign is a number from 1 to 254 in
hexadecimal (01 to FE). All signs leave the factory with a default
address of 1 or 01.
This serial address is resident in the InView display and is used for
RS485 networking. If one of the factory network communications
modules are used (2706-Pxxxx), this serial address is typically left at
its factory default and the network node or IP address is set in the
factory network communication module.
After you install a sign according to the Electrical and Mounting
Instructions, make sure the sign is installed properly by applying
power to it. The following information should be displayed on the
sign.
Power wiring must be in accordance with Class I,
Class II and Class III Division 2 wiring methods
(Articles 501-4(b), 502-4(b) and 503-3(b) of the
National Electrical Code, NFPA70) and in
accordance with the local authority having
jurisdiction.
Electrical Connections for
2706-P42, 2706-P43 and
2706-P44 Displays
• Firmware part number and version letter (xxxx).
• Amount of RAM in the sign, (256K).
• Serial address of the sign (a number from 01 to FE or from 1 to
254).
WARNING
To connect the 2706-P42, 2706-P43, and 2706-P44 displays:
1. Remove the power supply cover by unscrewing its 6 screws.

Download a Message
Application
InView message applications are created using the InView messaging
software (2706-PSW1). After creating the Message Application, you
need to download it into your InView display memory.
InView applications can be downloaded using:
• Point-to-point serial communications (RS-232) from the
communication port on a personal computer.
• Multi-drop RS-485 serial communications. Utilizing a
1761-NET-AIC to convert RS-232 to RS-485 from a personal
computer allows you to download to multiple displays over
RS-485.
• 2706-PCABLE1 which connects from your PC, running InView
messaging software, to the phone jack type connector on your
InView display. In larger InView models, this phone jack may be
behind the power supply cover.
• EtherNet TCP/IP networking. With the InView 2706-PENET1
EtherNet TCP/IP communication module you can download
message applications from a personal computer over Ethernet.
For more information on this communications option, see
publication 2706-IN008.
RS-232 to RS-485
Networking
• InView communication modules. The communication modules
allow the displays to communicate on the core Allen-Bradley
networks.
With the use of an Allen-Bradley 1761-NET-AIC, you can convert
RS-232 to RS-485 and daisy chain InView Displays up to 1219 m
(4000 ft).

RS-485 Echo
The RS-485 echo feature addresses the issue of increased network
traffic often caused by multiple node addresses and high consumption
of communication bandwidth. The display’s design enables users to
daisy-chain numerous InView displays off an InView P9x via the
RS-485 communication network.
2706-P9x - Master InView
RS-485 Network
In order to set the 2706-P92C display or the 2706-P94C display as a
Master, the echo dip switch must be enabled.
See Dip Switch Information for the 2706-P9x in Chapter 2.
TIP
Only one 2706-P9x InView display can be set as the
master per RS-485 network.
When the echo feature is enabled, all incoming packets, whether it is
over the RS-232 port, RJ12 download port, or the RJ45 10/100 base-T
Ethernet port, are echoed out the RS-485 port.
An InView master display inspects the incoming packets and
determine if the packet is addressed to itself and take the appropriate
action. The master shall ignore all packets that are not addressed to
itself. The only exception is for a packet with an address of 255. This
is the broadcast address and must be accepted by all displays on the
network.
TIP
When the 2706-P9x display, echo feature is enabled,
the RS-485 port of the 2706-P9x display, does not
accept incoming packets. The port is exclusively
used to echo out data.
Publication 2706-UM016D-EN-P - March 2006
Page 37
Install InView Marquee Message Display 1-29
Global Addressing
The 2706-P92C and 2706-P94C displays can both set their serial
address to 255, which is the global (broadcast) address. A display with
the serial address of 255, accepts all message packets regardless of the
address actually given in the packet. This allows the user to route all
messages to the 2706-P9x InView display.
See Dip Switch Information for the 2706-P9x in Chapter 2, for serial
address configuration.
Ground and Terminate the
RS-485 Network
TIP
Only one device at either end of the link must have earth ground and
shield jumpered together. This provides an earth ground connection
for the shield of this communication cable. If the connection is made
at an AIC or AIC+, jumper terminals 1 and 2. If the connection is made
at a 2706-P4x or 2706-P7x display, jumper terminals 1 and 8. If the
connection is made at a 2706-P22 display, jumper terminals 1 and 2.
Both ends of the network must be terminated. There is an impedance
of 120 ohms built into each AIC and AIC+ as required by the RS-485
specification. Jumper terminals 5 and 6 of the AIC or AIC+ for
end-of-line termination.
End-of-Line Termination for AIC and AIC+
A global address of 255 can only be set by hardware
and cannot be set using software.

This display operates at 18 to 30V dc. It has three communication
ports. These are the RJ-12, DB-9, and a six position terminal block
ports. The RJ-12 port is used primarily for downloading messages to
the display via the 2706-PCABLE1 download cable. The DB-9 port is
used for RS-232 communications and the signals are in parallel with
the RJ-12 port. Therefore, only one of the ports may be connected at a
time. The six position terminal block is used for RS-485
communications. The 2706-P22R display has a two-channel UART.
This means that one of the RS-232 ports and the RS-485 port can be
connected at the same time.

The 2706-P22R display has a ten-position dip switch. The first eight
positions are used to set the address of the display. Position nine is
used to put the display in diagnostic mode. Position ten is a spare.
The dip switch is read only on power-up.
The diagnostic mode causes the display of LED patterns to visually
indicate if any pixels are not turning on. It also performs a memory
check.
IMPORTANT
After one complete LED scan is done, a RAM check
is performed and the display’s memory is cleared. To
ensure that the display’s memory is not cleared, turn
off power to the display after the LED block test is
performed. Make sure that the download or message
file has been saved before diagnostic test is allowed
to run completely through.

There are two dip switches located on the controller board, Switch 1
and Switch 2.

Switch 1
Switch 1 is used to configure the display’s RS485 echo enable,
communication rate settings, and display size.
Publication 2706-UM016D-EN-P - March 2006
Page 43
InView System Connectivity 2-5
Position 1 enables or disables the echo function.
When you enable the RS485 echo function, this allows any packets
that come in on COM 0 (download, RJ-12 port), COM 1 (RS-232, TB3
port), and the Ethernet TCP/IP port to be sent out the RS485 port. This
allows Ethernet TCP/IP and other communication protocols to be
converted to RS485 by a single 2706-P92 or 2706-P94 and then sent
out to multiple RS485 networked displays.
TIP
Only enable the echo function on one
2706-P9x display.
Positions 3 and 4 set the communication rate.
Refer to page 2-6 for default positions.
If both switches are off, the communication rate can be set via the
InView messaging software. The dip switches take priority over the
software setting. If the communication rate is set to 19200 using the
software (positions 3 and 4 set to off) and then set to 9600 using
Switch 1 (position 3 on and 4 off), the communication rate is 9600.
Also, once positions 3 and 4 are used to set the communication rate
and then they are switched off, the communication rate setting
remains until it is changed by software or a different dip switch
setting.
Position 5 is used to set the display size. This is set by the factory.
Position 6 is used to turn on diagnostics.
Position 7 disables download message.
Switch 2
Switch 2 is used to set the serial address of the display. Position 1 is
the LSB of the address and position 8 is the MSB of the address.
If position 1 is on and all other positions are off, the display address is
1.
If position 8 is on and all other positions are off, the display address is
128.
If all positions are set to off, the serial address is set using the InView
messaging software.
Publication 2706-UM016D-EN-P - March 2006
Page 44
2-6 InView System Connectivity
The dip switch setting takes priority over the software setting. If the
serial address is set to 2 using the software (all the dip switches set to
off) and then Switch 2 is used to set the serial address to 3 (position 1
and 2 set to on and the remaining positions set to off), the serial
address is 3. Also, once Switch 2 is used to set the serial address and
then all switch positions are set to off, the serial address setting
remains until it is changed by software or the dip switch is set.

Display Setup
To set up your display:
1. Start the InView messaging software.
2. Create a project.
The software prompts for a project file name, a project name,
and description. Once this is done, the project name and
description appears in the Displays box.
3. The software then prompts for a display name, display
description, display type, and the number of that particular
display that is used in the system (1 to 100 of the same display
type).
4. Select one for the number of displays (once displays have been
assigned a unique address, more than one can be added at
once).
5. Select Next.
6. The software then prompts for the address of the display,
heartbeat, TCP/IP settings (if applicable), and the serial com port
settings.
Set the IP Address
Use the default settings of 9600, None, 8, and 1.
7. Select Next.
8. When the software prompts for a message file association, check
Create a New Message File.
9. Enter the message file name and select Finish.
The message editor window is displayed.
For the 2706-P22, 2706-P4x, and 2706-P7x terminals, separate
communication modules are needed to place the display on the
network. The 2706-P9x displays have Ethernet TCP/IP built in. To add
any other network protocol to the 2706-P9x, a separate
communication module is needed.
The Ethernet TCP/IP configuration utility is installed as part of the
Inview messaging software package. When first opening the InView
messaging software, you are asked to create a display and a message
file. After the display is created you can configure the IP address of
the 2706-PENET1 module.
Publication 2706-UM016D-EN-P - March 2006
Page 50
2-12 InView System Connectivity
The 2706-PENET1 module is the communication interface for Ethernet
TCP/IP. This module is used with the 2706-P22, 2706-P4x, and
2706-P7x displays. The 2706-P9x displays have this protocol built in.
Note that the 2706-PENET1 is Ethernet TCP/IP or Office type Ethernet
and is not Ethernet I/P, which is Ethernet Industrial Protocol available
on Rockwell Automation logic controllers.
To set the IP address:
1. Select the display you created, which use a the Ethernet module.
2. Right click on the display and select Edit Display.
TIP
Double-clicking on the display takes you to the
same window.
3. When the Edit Display window appears, go to the
Communications tab.
This is where the configuration utility is located.

6. Enter 3001 for the Port if using a 2706-PENET1 module.
7. Enter the MAC Address of the module under the heading Assign
IP Address.
The MAC Address is found on the module itself.
TIP
The 2706-P9x display does not use MAC Address. IP
Address changes must be done serially.
8. Click the Setup button located in the section titled Assign IP
Address once the desired IP Address, Port, and MAC Address
have been entered.
If the IP Address is already in use, an error message window
appears.
TIP
If the Invalid IP Address window appears, click
OK, choose a different desired IP Address, and
click the Setup button again. Once a valid IP
Address is entered, the following window should
appear saying it is ready to assign an IP address.
Publication 2706-UM016D-EN-P - March 2006
As the message instructs, you need to either turn the display on
or power cycle the display if it is already turned on. Upon
successfully assigning an IP Address the following window
appears.

Gateway Address and Subnet Mask Setup
Set up the Gateway address and Subnet Mask if needed based on your
Ethernet Network configuration. Default values typically are for
Subnet Mask, 255.255.255.0 and as a default the Gateway address is
left blank.
Subnet Mask is a parameter that interprets IP addresses when the
network is divided into multiple networks. The IP address is formatted
as four sets of decimal numbers with periods between them
(255.255.255.1). The range of values for the first set of decimal
numbers is 1 to 255. The range of values for the last three sets of
decimal numbers is 0 to 255. The value 0.0.0.0 is not a valid subnet
mask.
Gateway Address is a unique address of the Gateway connecting two
individual IP networks into a system of networks. When a node needs
to communicate with a node on another network, the Gateway
transfers the data between the two networks. The IP address is
formatted as four sets of decimal numbers (from 1 to 255) with
periods between them (130.0.0.1). The first field cannot be 0 if any
other fields contain a 0.
Once the desired Gateway Address and Subnet Mask have been
entered, click on the Setup button located just below where the
Subnet Mask was entered. If for some reason, the settings are not
received by the 2706-PENET1 module, the following error message
will appear.
However, upon successfully setting up the Gateway Address and
Subnet Mask, the following message appears telling you to cycle
power to the module.
Publication 2706-UM016D-EN-P - March 2006
Page 54
2-16 InView System Connectivity
After the IP Address, Gateway Address and Subnet Mask have all been
established, click the OK button on the bottom of the Ethernet TCP/IP
Communications window. This allows the settings to be saved and
configuration is now complete.
Once the settings have been saved, they can now be viewed by
clicking on the Advanced button located in the section titled TCP/IP
settings on the Edit Display window.
Create the Message File
A background message of Rockwell Automation is automatically
created. This is also indicated by the letter B in the message list below
the message creation box. Message number 1 is highlighted and ready
for creation. Create a message by typing in the message box.
Attributes for the messages can be changed or added using the pull
down menus located above the message creation box or from the
toolbar. Once message number 1 has been created, select the down
arrow or type 2 in the box and select the Goto button. This allows
message number 2 to be created.
There is a size displayed in the lower right of the window. This is the
size of the message that is being created. This number starts from 11
and increases to a maximum number that is determined by setting the
partition size in software. This is based on a total of 200,000 bytes.
The smaller the partition size the more messages are available. The
limits are 450 bytes per message, 444 messages minimum to 50 bytes
per message, 4000 messages maximum. To change the partition size,
select File then Partition.
See the following sections for more information regarding the
message attributes.

Attach a Note to a Message
Select a message from the message list. Select Tools and Edit Note.
Then a Message X Note window appears. The X is the message
number for the message that a note is being created for. These
message notes can only be viewed with the InView messaging
software and are not downloaded to the display.
Text Color
There are three color options if a display is classified as color. They
are red, green, or yellow. The color of the message is the color that is
selected. The color of individual text within the message is changed
by inserting a color before the text. The text after the color insert stays
that color until a new color insert is performed.
Date, Time and Variables
The date, time and variables are also inserted into a message. These
are found under the Edit menu then Insert or via the toolbar buttons.
If inserting the date, a pop-up window appears and shows various
formats and a pre-viewer that displays the data for the selected format.
If inserting a variable, a pop-up window appears that allows the
selection of the variable number and whether the variable is numeric
or alpha numeric. The maximum number of variables per message file
is 100 (00 to 99). The numeric variable ranges from 32,767 to -32,768
decimal. It also allows the selection of the type of padding and a
check box for a sign (+/-). An alpha numeric variable is ASCII text
except for the “. It also varies in length from 1 to 128 characters. There
is a pre-viewer that displays the options selected. The format for the
time is either standard or military. The selection for this is found in the
Publication 2706-UM016D-EN-P - March 2006
Page 56
2-18 InView System Connectivity
InView configuration window (the project window) under Tools and
Set Display Date and Time. Note that the time format is set for each
display individually by address. The default format is standard. The
data and time is also set here.
Category
The Category option is used to assign categories to messages. This
helps in organizing messages for certain operations and when
performing a find.
Message Priorities
The Priority option is used to give messages a priority of low,
medium, and high. As an example, a normal operating water
temperature reading of a generator is a low priority message. A
pre-alarm message of high water temperature is a medium priority
message. An alarm message of high water temperature shutdown is a
high priority message.
In our example, the water temperature is part of the generator signals
that are constantly being monitored and displayed as low priority
signals in the message queue (the message queue can hold up to 64
messages). When the water temperature rises above a pre-alarm
threshold, the medium priority high water temperature message is
added to the message queue. When this happens, only medium
priority messages are displayed. If other medium priority messages
were added to the queue, they are also displayed until a high priority
message is added to the queue. When the water temperature rises
above an alarm threshold, the high priority high water temperature
shutdown messages are displayed.
In order to view the low priority messages, the medium and high
priority messages need to be removed from the message queue.
See InView Protocol, Chapter 4, for information on how to add or
remove messages from the message queue.
Publication 2706-UM016D-EN-P - March 2006
Page 57
InView System Connectivity 2-19
Pause
The Pause option determines how long a message is displayed when
a message queue (two or more messages are being displayed due to a
download and display or messages were added to a message queue)
is running.
See InView Protocol, Chapter 4, for information on how to messages
to the message queue.
Message Header
A header is added to a message by clicking the H button. Once this
button is clicked, the button appears depressed and any text in the
message creation box shifts from the top line to the bottom line.
Preview Messages
Messages are previewed before downloading. This option is found
under the View menu then Preview Mode or by clicking the
magnifying glass button.
After the message file is created, exit the message editor. The message
file is automatically saved as it is created. If an edit is needed to a
message file, double click a message in the Message File Details list in
the project window. This brings up the message editor window.
Set the Display Address
All displays except for the 2706-P9x and 2706-P22R displays must
have their addresses set through software. The factory default address
setting for all InView displays is 01. This is the old address when
setting up the display for the first time. To set the display address
using the software, select Tools and Set Display Address. The display
communication settings (com port and communication rate, or TCP/IP
settings) should have been set when the display was added to the
project.
The 2706-P22R display address is set either in the software using
InView messaging or by using the dip switch. The first eight positions
of the dip switch are used for setting the display address. If all the dip
switches are off, the address is set in the software. If any of the first
Publication 2706-UM016D-EN-P - March 2006
Page 58
2-20 InView System Connectivity
eight dip switch positions are on, this is the display address and the
software setting is overwritten. Once an address is selected by the dip
switches, it is retained until it is overwritten by the software (only
done when all switches are off) or the dip switches are changed.
Once a unique address has been set, future display properties and
message communications are done to networked signs via RS-485.
Message downloads, communications, and display properties are
done to networked signs via Ethernet TCP/IP.
See the 2706-PENET1 pdf in the Product Literature folder on the
InView Messaging Software CD for more information on using this
communication option.
Download Messages
Once the message file has been created, there are several download
options.
• Download the entire file - Download Message File and
Broadcast Download
• Download selected messages - Download Message
• Download and display selected messages - Trigger Message and
Broadcast Trigger Message
• Message broadcast – Broadcast Download Message
A pop-up window appears when any of these options, except for
broadcast, are selected. This window allows the selection of which
displays to download to.
TIP
Assign the address and communication settings for
each display before any messages are downloaded.
These options are found under Message File and
Message.
Download Message File and Broadcast Download
Broadcast Download downloads the entire file to all displays on the
network. Download Message File downloads the entire file to the

overwrite the old messages starting at message number one to where
the new messages end. If the old message file has more messages
than the new message file, the old messages above the new message
Publication 2706-UM016D-EN-P - March 2006
Page 59
InView System Connectivity 2-21
file end remains. For example, the old message file had messages 1
through 10 and a background message. The new message file has
messages 1 through 2 and a background message. After the new
message file is downloaded, the new message file contains new
messages 1 through 2, a new background message, and old messages
3 through 10. If the new message file does not contain a background
message, the background message is blank. If just the new message
file is to be retained in memory, a clear memory operation should be
performed before downloading a new message file. This erases the
entire memory of the display.A message trigger or addition to the
queue is required in order to view the downloaded messages.
See InView Protocol, Chapter 4, for information on how to trigger a
message or add it to the queue.
Download Message
Download Message downloads only those messages selected from the
message list. To select messages, highlight them from the Message File
Details box in the InView messaging software (project) window. Once
they have been downloaded, the display behaves the same as if the
entire message file were downloaded. A message trigger or addition to
the queue is required in order to view the downloaded messages.
See InView Protocol, Chapter 4, for information on how to trigger a
message or add it to the queue.
Trigger Message and Broadcast Trigger Message
Trigger Message and Broadcast Trigger Message allows up to 64
messages selected from the message list to be displayed after
download. This is the message queue. Each message is displayed for
the amount of the pause time that is set when the message is created.
TIP
If new messages are downloaded using this option, a clear message
queue command is done before the messages are downloaded. The
old messages are erased and replaced with the new ones. Broadcast
Trigger Message downloads the selected messages to all displays on
the network.
Only messages of the highest priority are displayed.
When using this option, ensure that all the messages
have the same priority.

Clear Memory/Message Queue
These options are found under Tools then Clear Display Memory and
Clear Display Message Queue. The clear memory option erases the
entire memory of the display. Memory Cleared is displayed and then
the display goes through a reset cycle. The clear message queue
option just erases the queue, not the display memory. If there is a
background message, it is displayed after a clear message queue
command has been issued.

Introduction
Trigger Messages and
Update Variables
The purpose of this chapter is to show the protocol that is required to
trigger messages and update variables on InView displays with the
InView protocol.
In general, messages are downloaded through the software and stored
within the display memory. Up to 4000 messages and 100 (0 to 99)
variables can be created with the InView software.
Messages are displayed using the Control-T function or Modbus ASCII.
One of three different methods can be used.
• Priority messaging
• Add a message
• Remove a displayed message
Variables are updated using the Control-V function or Modbus ASCII.
The two functions that are used to trigger messages and update
variables are the Control-T (CRTL-T) and the Control-V (CTRL-V). The
CTRL-T function allows for two different ways of displaying messages,
priority messaging and add/remove messages. The CTRL-V function is
used to update variables on all displays or a specific display.
Priority messaging displays the message number that was just
transmitted to the display. Using this function has precedence over
any priority levels that are used with add/remove messages.
Add/remove messages allows for up to 64 concurrently running
messages to be shown on the display. Messages are cleared one at a
time or all at once. These messages have priority levels assigned to
them that are used to determine how they are displayed.
The CTRL-T Function Frame
The CTRL-T function is used to trigger messages. This function
requires an ASCII decimal value to be used to trigger the desired
message number. The CTRL-T function has the ability for priority
messaging, add a message, or remove a message. Control-T Frame

Use a priority message to clear all concurrently running messages and
display the message number just sent. This supersedes any message
added to the queue regardless of priority levels assigned to them.
Add/remove messages allows for the ability of up to 64 concurrently
running messages to be displayed. Messages are added to the queue
and are displayed for the length of time based on the message pause
setting (1 to 5 seconds). Messages have three different priority levels
assigned to them; low, medium, and high. Messages with the highest
priority level in the queue are displayed until they are cleared. When
Publication 2706-UM016D-EN-P - March 2006

InView Protocol 4-3
all messages are removed or cleared, the background message
(message # 4095) is displayed.
TIP
If no background message is programmed, the
default message NO BACKGROUND MESSAGE
appears.
The CTRL-V Function Frame - Numeric Variables
The CTRL-V function is used to update variables that are embedded
within messages. The value of the variable number determines which
variable register is updated in the display. If no display address is
used, it updates all displays with the variable data. The Control-V
Frame Format shows the format for updating variables and the
Control-V Frame Description shows the acceptable values for the
CTRL-V function.
If the Variable # and Display address are not used; only variable 0 on all displays will be updated. If the Variable # is used and not the Display address, that variable
number will be updated on all displays.

TIP
To send floating point numbers, you need to use 2
variables; one for the integer portion, and one for the
decimal portion. i.e {var1;}.{var2;}.
The CTRL-V Function Frame - Alphanumeric Variables
The Ctrl-V Function is used to update variables that are embedded
within messages. The value of the variable number determines which
register to update in the message display. If no variable number is
used, only variable 0 is updated. In addition, you can flash or change
the color of the variable data.
If the Variable # and Display address are not used; only variable 0 on all displays will be updated. If the Variable # is used and not the display address, that variable
number will be updated on all displays.

Flash Variable Data
You can enable/disable flashing for the variable data by using [Ctrl] G1
to turn the variable on and [Ctrl] G0 to turn the variable off.
For example, to flash the word text in the variable data how to flash
text, you must enter the variable data as:
how to flash [Ctrl]G[1]text[Ctrl]G[0]
Change Color of Variable Data
To change the color of variable data, you must add the following
characters to the variable data for the specific color.
\1C1 for red
\1C2 for green
\1C3 for yellow
Examples of the Control-T
Function
For example, the variable data how to show the color is set to display
as red. If you want to modify the variable data so the words to change
the display as green with the remaining data red, you must set the
variable data up as follows:
how \1C2 to change the \1C1 color
There are two basic ways in which messages are displayed: priority
messaging or add/remove messages. When using either of these
methods, the messages are shown on one or all displays.
Trigger a Message on all Displays using Priority Messaging
A message can be shown on all displays one of three different ways.
These examples show the Control-T function being used to show
message number 45 on all displays.
The following removes all messages on all displays and automatically
displays the background message (4095) without adding the
background message number to the message queue.
The following removes all currently running messages on a display
address 024 and automatically displays the background message
(4095) without adding the background message number to the
message queue.
This function allows for the updating of variables that are embedded
in messages. If no display address is used, it updates all displays with
the variable data. The following example updates variable 0 in all
displays.

Messages
Modbus ASCII is an industrial data communications protocol that has
been implemented in Allen-Bradley’s InView Protocol. It is a master
and slave protocol providing for one master and up to 247 slaves.
Each slave is assigned a unique address, because only the master can
initiate a transaction. The protocol controls the query and response
that takes place between master and slave devices as in Figure .

ASCII protocol and limited InView Sign Communication protocol
(used during the download and preview of messages). Messages are
pre-loaded into the displays, and then triggered by writing Modbus
ASCII instructions to specific registers in the display.

Below are several terms used throughout the Modbus ASCII section.
• ASCII - American Standard Code for Information Interchange.
• LRC - Longitudinal Redundancy Check used for error checking.
• RTU - Remote Terminal Unit.
• Query – Sending information to a node address where a
response is expected.
• Response – A response is given to a Query.
• Transmission – Sending information to all node addresses where
no response is expected.
How InView Sign
Communication Protocol is
used with Modbus ASCII
Protocol
There are two different modes of transmission used with Modbus
protocol, Modbus ASCII and Modbus RTU. In this case, Modbus ASCII
is used. Modbus ASCII protocol is used to accomplish such functions
as Priority Messaging, Add a Message, Remove a Message, Update
Variables, and reading register in the Message Queue or Variable.
The basic framing format that is used in the Modbus ASCII is shown in
the section Add a Message on all Displays on page 4-7.

Downloading messages to the displays using Modbus ASCII protocol
requires a special function in order to pass Allen-Bradley’s InView
industrial protocol to the displays. To accomplish this, a Modbus 01
function or frame is specifically used to encapsulate the InView
protocol. The downloading of messages that are created using
automation software automatically encapsulates the protocol in the
Modbus ASCII string.

To encapsulate the InView protocol a Modbus ASCII header and
trailer are used. The automation software has message length range
from 50 to 450 Bytes. This is only the maximum length of the InView
protocol that is encapsulated within the Modbus ASCII protocol.
When downloading messages on a Modbus network, the maximum
length of the Modbus ASCII and the InView protocol is 500 bytes.

Messages are downloaded to all displays on the Modbus ASCII display
network. A broadcast address is used that requires no response from
the displays. Modbus ASCII protocol uses address 00h for
broadcasting information from one device to the next. This is
generally reserved for PLC to PLC communications. For this reason,
address 255 (0xff) is used.
Mode of Transmission
Mode of transmission is the format in which messages are transmitted
over the network. Characteristics of the Modbus ASCII system are:
Coding Systems - hexadecimal (uses ASCII printable characters:
0-9, A-F).
Modbus allows the format for data transmission.
• Communication rate: user selectable
• Format: Number of bits per character - 1 start bit, 7 data, 1
(optional) parity bit, 1 or 2 stop bits.
For the products, the data communication rate and format shall be
9600 baud (maximum), 1 start bit, 7 data bits, even parity, 2 stop bits.
InView Display Memory Map
Information transmitted to the displays writes or reads information
into holding registers. The holding registers used in the products are
40001 to 40167. Holding registers 40001 to 40103 can be written to.
Registers 40001 to 40100, and 40103 to 40167 can be read from.
The product has three basic areas for registers, 100 registers for
variables, 3 registers for message control, and 64 registers for the
message queue. When referencing a holding register, Modbus ASCII
requires that 40001 be subtracted from the holding register address.
Publication 2706-UM016D-EN-P - March 2006
Page 79
InView Protocol 4-13
For example, when using priority messaging, messages are sent to
holding register 40103. The register number that is transmitted would
be (40103-40001=102) or 102 (0x66) would be transmitted at 100
(64h). The following shows the memory map for the displays.

Methods of Transmission
There are eight different methods of transmission of data to and from
the display. Each one of these use 1 of 4 different Modbus function
codes.
The table, Modbus Function Codes used in InView Products, explains
each of the four Modbus ASCII function codes used. The table,

Message Format
Messages are transmitted at 9600 baud, and starts with a beginning of
frame : and ends with a carriage return (CR) line feed (LF) to indicate
the end of frame. The line feed character also serves as a
synchronizing character to indicate that the transmitting station is
ready to receive an immediate reply.
The Modbus ASCII message frame format consists of an address field,
a function field, a data field, an LRC or error check field, an end of
frame field (EOF), and a ready to receive response field (LF). The EOF
is a carriage return (0x0d), and the LF is a line feed (0x0a).

Beginning of Frame Field
Each transmission will start with a : and is used to signal the receiving
device that message packet follows.
Address Field
Each slave must be assigned a unique address. When a master sends
to a specific slave address (query), the slave sends a response
(response) message back to the master. When a master sends a
message to a specific display address (001 to 247), the slave will give a
response if the message data is correct. All other slaves will ignore the
data transmission.
When a master sends a broadcast message addressed of 255 (0xff),
then all slaves interpret this as an instruction to read and take action
on the message. No response message is required.
Modbus allows 001 through 247 for unique addresses that are used on
a network. The products allow for address 001 through 255, with 255
being the broadcast address. Since some networks may not support
address 248 through 255, then the broadcast address may not be used,
and message queries are always guaranteed. If Modbus message
transmissions are being generated from a serial port, then addressing
from 001 through 255 are valid.
TIP
When a query/response is used for sending
messages to the display, the display responds back
to the host in less than 10 ms after receiving the Line
Feed field (0x0a).
Function Field
The function field tells the address slave what function to perform.
There are only four functions that are applicable to the display
application.
Publication 2706-UM016D-EN-P - March 2006
Page 82
4-16 InView Protocol
Data Field
The data field contains information on the specific action that the
slave must perform.
Error Check Field
The error checking is the LRC of the message and allows for the
master and slave to detect message errors. A response message is only
sent, if the original message was received correctly.
The following shows a simulated query and response.
Simulated Query and Response
End Of File Field
This field is used to signify the end of file for the transmission. It uses
a Carriage Return (0x0d).
Line Feed Field
This is the ready to respond field file (LF) and uses a line feed (0x0a).
Longitudinal Redundancy Check (LRC) Error Detection and
Calculation
Some sort of error detection is needed, because communication errors
can occur in an industrial environment due to machinery noise and
electromagnetic interference. The method for error detection used
with Modbus ASCII is Longitudinal Redundancy Check (LRC). The LRC
is an 8-bit binary number represented and transmitted as two ASCII
Hexadecimal characters. The LRC is produced by adding the message
characters (ignoring the carry bit) and taking the two's compliment of
Publication 2706-UM016D-EN-P - March 2006

the result. The error check byte is done from the address up to the
data field.
The following is an example of how to calculate the LRC in a Modbus
ASCII transmission.

Examples of Modbus ASCII
Functions
Transmitted as70
The following sections show examples of Modbus ASCII protocol
Query/Response transmissions to/from a display for each command
instruction listed above. Modbus ASCII will write/read to the holding
registers in the display. These registers are in the 40000 range. When
writing to register 40101, 40001 is dropped from the address leaving
100 (0x64). The following example shows the transmission of data to
holding register 40102 in all displays. The display adds 40001 to the
starting address upon receiving the transmission before updating the
appropriate holding register.
Format for the following sections is the use of a query/response or a
transmission. Each section shows the complete transmission and
response (if applicable). In some examples, there are multiple steps
that are needed to complete the function requested. Within these
steps, there are pause or delay times that must be used in-between
each step.
The data that is sent is ASCII information and the CR and LF
represents 0x0d and 0x0a respectively. The beginning of frame (:)
represents (0x3a).
Heartbeat Function
The heartbeat function, when enabled, allows the display to
determine if it is no longer on the network or if the host device is not
functioning properly (not sending data or a heartbeat). Should the
display not see any serial activity (valid or invalid) within 3 seconds,
an error message No Network Activity is displayed. The heartbeat is
either enabled or disabled via protocol or software.
Factory Default: DISABLED.
Enable the Heartbeat Function
The displays are shipped with the heartbeat disabled. Should the
heartbeat function be required, the following string of information
enables the display to look for a heartbeat or serial activity.

Preview a Message
TIP
Four separate types of transmissions are required for message
preview. This is primarily done using the automation software to
preview a message. First, clear the Message Queue. Second,
download the message to the appropriate memory partition. Third,
trigger the message triggered for viewing. Fourth, generate a heartbeat
(if enabled) so that there is some serial network activity allowing the
message to be previewed. The software automatically performs these
steps.
A message preview is not recommended for
run-time.
TIP
Message preview causes the loss of data in the
memory partition where the message is stored.
This is an example of previewing Message #0001 as a target memory

steps that must be done to accomplish this. First, set the memory size.
Second, messages are then downloaded. Third, clear the queue.
It may be necessary to clear the memory in the display prior to
downloading of messages. This can be done either through a serial
transmission from the InView messaging software (2706-PSW1), or
ladder logic commands.

Add/Remove a Message using a Modbus ASCII 10 Frame Query
(Recommended)
This method uses both registers 40101 and 40102 in the display to add
and remove a message from the message queue respectively. By using
the Guaranteed mode, only the display that is addressed on the
network accepts and processes the information it receives. The
following is an example of adding message #0015 and removing
message #0045 from the message queue on display number 019.
