Installing InView Marquee

Message Display

Section 1.1 Introduction

These instructions show you 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 or outdoor use depending on the NEMA standard.

• 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 hose­directed water.

• Type 12 enclosures are in a sealed case that is, dust free, gasketing, and

spray-down resistant.

Section 1.2 Wire and Safety Guidelines

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.

NOTE

You can configure your InView Messaging software without having an
InView display connected.

• 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.

EXPLOSION

HAZARD

Identifies information about practices or circumstances that can cause
an explosion in a hazardous environment, which may lead to personal
injury or death, property damage, or economic loss.

User’s Manual 0300277-02 Rev. D

AVERTISSEMENT

Actions ou situations risquant de provoquer une explosion dans un

environnement dangereux et d’entraîner des blessures pouvant être

mortelles, des dégâts matériels ou des pertes financières.

NOTE

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, NFPA 70) and in accordance with the local
authority having jurisdiction.

Section 1.3 Change the Serial Address

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 RS-485
networking. If one of the factory network communications modules are used
(2706-Pxxx-SCx), 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.

Section 1.4 Checkout Procedure

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.

• Firmware part number and version letter (xxxx).

• Amount of RAM in the sign, (256 K).

• Serial address of the sign (a number from 01 to FE or from 1 to 254).

User’s Manual 0300277-02 Rev. D

Section 1.10 Download a Message Application

InView message applications are created using the InView messaging software
(2706-PSW1-SC). 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-SC 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-SC

EtherNet TCP/IP communication module you can download message
applications from a personal computer over Ethernet.

• For more information on this communications option, see 0100233-

01_A0(INSTALLATION_INSTRUCTIONS,2706-PENET1-SC).

• InView communication modules. The communication modules allow the

displays to communicate on the core Allen-Bradley networks.

Section 1.11 RS-232 to RS-485 Networking

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).

Chapter 1: Installing InView Message Display 1-29

User’s Manual 0300277-02 Rev. D

1.11.1 1761-NET-AIC (AIC+)

1.11.2 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-SC via the RS-485 communication network.

In order to set the 2706-P92-SC display or the 2706-P94-SC display as a Master,
the echo dip switch must be enabled.

See Dip Switch Information for the 2706-P9x-SC in Chapter 2.

NOTE

Only one 2706-P9x-SC InView display can be set as the master per RS­485 network.

When the echo feature is enabled, all incoming packets, whether it is over the

1-30 Chapter 1: Installing InView Message Display

User’s Manual 0300277-02 Rev. D

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 determines if the
packet is addressed to itself and take the appropriate action. The master ignores
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.

NOTE

When the 2706-P9x-SC display, echo feature is enabled, the RS-485 port
of the 2706-P9x-SC display, does not accept incoming packets. The port is
exclusively used to echo out data.

Section 1.12 Global Addressing

The 2706-P92-SC and 2706-P94-SC 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-SC InView
display.

See Dip Switch Information for the 2706-P9x-SC in Chapter 2, for serial address
configuration.

NOTE

A global address of 255 can only be set by hardware and cannot be set
using software.

Section 1.13 Ground and Terminate the RS-485 Network

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-SC or 2706-P7x-SC display,

jumper terminals 1 and 8.

• If the connection is made at a 2706-P22R-SC display, jumper terminals 1

and 2.

Both ends of the network must be terminated.

Chapter 1: Installing InView Message Display 1-31

User’s Manual 0300277-02 Rev. D

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 end­of-line termination.

NOTE

End-of-line InView display should have a terminating resistor in RJ11
(P1). If a 2706-P22-SC display is the end-of-line display, jumper terminals
5 and 6. There is a built-in impedance of 120 ohms similar to that of the
AIC and AIC+.

attributes, communications and create messages.

Section 2.1 Serial ASCII Communications

Refer to Chapter 3 for more information on Serial ASCII communications from
Channel Zero of an Allen-Bradley controller

Section 2.2 Features

The features are separated into sections for the 2706-P4x-SC and 2706-P7x-SC
displays and the 2706-P22R-SC displays.

Section 2.3 2706-P42-SC, 2706-P44-SC, 2706-P72-SC, and 2706-P74-SC Displays

These displays operate at 100 to 240 VAC. They have an eight-position terminal
block that contains an auxiliary +5 VDC, RS-232 signals, and RS-485 signals.
There is also an RJ12 port that is in parallel with the RS-232 signals from the
terminal block. The RJ12 port is used primarily for downloading messages to the
display via the 2706-PCABLE1-SC download cable.

These displays have a single channel UART and therefore can only have one of
the three communication options connected at a time:

• RJ12

• RS-232 terminal block connections

• RS-485 terminal block connections

This display operates at 18 to 30 VDC. It has three communication ports. These
are the RJ12, DB-9, and a six-position terminal block port. The RJ12 port is used
primarily for downloading messages to the display via the 2706-PCABLE1-SC
download cable. The DB-9 port is used for RS-232 communications and the
signals are in parallel with the RJ12 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-SC 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-SC 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.

2.6.1 Dip Switch Information for the 2706-P9x-SC

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

2.

2706-P9x-SC Dip Switch

Switch 1

Switch 1 is used to configure the display’s RS-485 echo enable, communication
rate settings, and display size.

Position 1 enables or disables the echo function.

Chapter 2: InView System Connectivity 2-5

User’s Manual 0300277-02 Rev. C

When you enable the RS-485 echo function, this allows any packets that come in
on COM 0 (download, RJ12 port), COM 1 (RS-232, TB3 port), and the Ethernet
TCP/IP port to be sent out the RS-485 port. This allows Ethernet TCP/IP and
other communication protocols to be converted to RS-485 by a single 2706-P92­SC or 2706-P94-SC and then sent out to multiple RS-485 networked displays.

NOTE

Only enable the echo function on one 2706-P9x-SC 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 display address is 128.
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.

Multiple Communication Rate Support

The 2706-P92C-SC and 2706-P94C-SC displays allow you to select serial
communication rates of 9600, 19200, or 38400 bps. The communication rates are
both hardware (dip switches) and software selectable.

NOTE

For selecting the communication rate using the dip switches, see the
section entitled Dip Switch Settings.

The communication rate of the display is set using the InView messaging
software, provided the communication rate dip switches are all off.

To set the communication rate using the messaging software:

1. Highlight the 2706-P9x-SC display you wish to set the communication

rate:

2. Select Set Display Baud Rate under the Tools menu:

User’s Manual 0300277-02 Rev. C

3. Choose the communication rate you wish to set the display at and click

on the Set button:

NOTE

There is no confirmation that the command was sent. The display must be
power cycled to view the new communication rate settings.

Isolated Communication Ports

The isolated communication ports consist of RS-232, RS485, 10/100 Ethernet
port and a RS-232 download port. This allows the 2706-P92C-SC and 2706­P94C-SC displays to support multiple networks simultaneously. This allows
programmers to change the messages or tie into an information database, while
control operators can continue delivering alarms and messages to the plant floor.

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.

The software then prompts for the address of the display, heartbeat,
TCP/IP settings (if applicable), and the serial com port settings.

Use the default settings of 9600, None, 8, and 1.

6. Select Next.

7. When the software prompts for a message file association, check Create

a New Message File.

8. Enter the message file name and select Finish.

The message editor window is displayed.

Set the IP Address

For the 2706-P22-SC, 2706-P4x-SC, and 2706-P7x-SC terminals, separate
communication modules are needed to place the display on the network. The
2706-P9x-SC displays have Ethernet TCP/IP built in. To add any other network
protocol to the 2706-P9x-SC, 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-SC module.

The 2706-PENET1-SC module is the communication interface for Ethernet
TCP/IP. This module is used with the 2706-P22-SC, 2706-P4x-SC, and 2706­P7x-SC displays. The 2706-P9x-SC displays have this protocol built in.

Note that the 2706-PENET1-SC 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.

Chapter 2: InView System Connectivity 2-11

already turned on. Upon successful assignment of 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-SC module, the
following error message will appear:

2-14 Chapter 2: InView System Connectivity

User’s Manual 0300277-02 Rev. C

However, upon successfully setting up the Gateway Address and Subnet Mask,
the following message appears telling you to cycle power to the module:

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, followed by Partition.

See the following sections for more information regarding the message attributes.

Chapter 2: InView System Connectivity 2-15

Message File Additional Information

Additional tasks covered in the following section are:

• Attach a Note to a Message

• Text Color

• Date, Time and Variables

• Category

• Message Priorities

• Pause

• Message Header

• Preview Messages

• Set the Display Address

• Download Messages

• Clear Memory/Message Queue

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 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

2-16 Chapter 2: InView System Connectivity

User’s Manual 0300277-02 Rev. C

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.

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, followed by accessing 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-SC and 2706-P22R-SC 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-SC 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 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 downloaded to networked signs via RS-485. Message
downloads, communications, and display properties are downloaded to

Chapter 2: InView System Connectivity 2-17

User’s Manual 0300277-02 Rev. C

networked signs via Ethernet TCP/IP. See the 2706-PENET1-SC documentation
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.

NOTE

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 display specified.
Download Message File and Broadcast Download 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
remain above the new message TIP

Assign the address and communication settings for each display before any
messages are downloaded. These options are found under Message File and
Message.

The files at the end remain. 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.

2-18 Chapter 2: InView System Connectivity

User’s Manual 0300277-02 Rev. C

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.

NOTE

Only messages of the highest priority are displayed. When using this
option, ensure that all the messages have the same priority.

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

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.

Chapter 4 InView Protocol

Section 4.1 Introduction

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.

Section 4.2 Trigger Message and Update Variables

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.

4.2.1 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 Format shows the format for the Control-T
function and Control-T Frame Description shows the acceptable values.

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 all messages are removed or cleared, the background
message (message # 4095) is displayed.

NOTE

If no background message is programmed, the default message NO
BACKGROUND MESSAGE appears.

4.2.2 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.

4.2.3 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.

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
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:

Section 4.5 Modbus ASCII Protocol to Download and Preview 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.

The Modbus ASCII protocol is incorporated into the InView Industrial Protocol
that allows displays to connect to a Modbus ASCII communications network.
These displays receive applicable Modbus 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.

Section 4.6 Master and Slave Query/Response Cycle

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.

Chapter 4: InView Protocol 4-9

User’s Manual 0300277-02 Rev. D

Section 4.7 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.

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.

The following table shows the format of the 01 Frame used for the downloading
of messages to the displays.

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 (0×ff) 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

4-10 Chapter 4: InView Protocol

User’s Manual 0300277-02 Rev. D

• 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 is 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.

For example, when using priority messaging, messages are sent to holding
register 40103. The register number that is transmitted would be (40103­40001=102) or 102 (0×66) 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 uses 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, Methods of Transportation,
shows the eight methods of using these codes with the product.

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 (0×0d), and the
LF is a line feed (0×0a).

Beginning of Frame Field

Each transmission will start with a colon (:) 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 (0×ff), 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.

NOTE

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
LineFeed field (0×0a).

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.

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.

Chapter 4: InView Protocol 4-13

User’s Manual 0300277-02 Rev. D

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 (0×0d).

Line Feed Field

This is the ready to respond field file (LF) and uses a line feed (0×0a).

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 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

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 (0×64). 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.

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 0×0d
and 0×0a respectively. The beginning of frame (:) represents (03a).

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.

Transmission is as follows:

Preview a Message

Chapter 4: InView Protocol 4-21

User’s Manual 0300277-02 Rev. D

NOTE

A message preview is not recommended for run-time.

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.

NOTE

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 position.

1. Clear the message queue.

This transmission is used to remove all currently running messages on
the display for all displays.

Download Messages

Messages can be downloaded to the display so that they can be triggered (or
activated) at a later time. The download of messages is generally done using the
InView messaging software but can be done from ladder logic using the
instructions below. There are three basic 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-SC), or ladder logic commands.

Download Three Messages Example

This example shows the display downloading three messages (with three
different priority levels). Setting the message size to 200 bytes (0×C8) for each
message.

1. Set the message partition size in the display(s) to 200 bytes.

Read Variables in a Display using a Modbus ASCII 03 frame

This function allows the ability to read variable data stored in a display. A
maximum of 100 registers can be read since there is a maximum of 100 registers
of data. Below is an example of the request for registers 40002 through 40004 in
display address 020.

Transmission as follows:

Response:
The addressed slave responds with its address and the function code, followed by

the information field. The information field contains 2 bytes describing the
quantity of data bytes to be returned. The contents of the registers requested
(DATA) are two bytes each, with the binary content right justified within each
pair of characters. Below shows the response to query for registers 40002
through 40004 having the decimal contents of 44, 63, and 1 respectively.

The normal response to a function 03 query is to echo the address, function code,
starting address and the data for the registers that were requested.

Change the InView Display Address

This function allows the ability to change the serial address in a display. For
example, change display address 001 to address 020. When doing this, you need
to know the address of the display you want to change. This is typically done
using the automation software. The following is an example of changing a
display (with the address of 005) to address 004.

Transmission is as follows:

InView Display Communication Protocol Functions and Descriptions

The InView display communication protocol that is used in conjunction with the
Modbus ASCII protocol is mostly limited due to the number of functions and
features that required by the InView products. This Protocol can be used for
downloading new messages of alpha numeric messages from an Allen-Bradley
controller.

InView Message Format used within Modbus ASCII Protocol

Information that is used within the InView message is formatted differently than
that of the standard protocol. The following table shows the basic message structure
with a brief explanation of each part.

Items in Bold must be used in each transmission. The automation software will
automatically put this information into the message that is transmitted. Some of
these functions are modified from the InView protocol that is used in the
standard product line, for example, message number versus file labels. Below is a
list of the valid values for each of the fields shown above. Each of these are
concatenated together to make up the InView message.
