Introduction

Wire and Safety Guidelines

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.

WARNING

1 Publication 2706-UM016D-EN-P - March 2006

EXPLOSION HAZARD

Do not connect or disconnect equipment unless power has been switched off and area is known to be non-hazardous.

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.

Save the screws for a later step.

Hazardous voltage. Contact with high voltage may cause death or serious injury. Always disconnect power to sign prior to servicing.

Hole plugs, top, removed

Wing nuts for hole plugs

TIP

It is recommended that you install power and serial wires at the bottom of the power supply enclosure to reduce noise from power wires crossing serial wires.

You can install the power or serial wires at the top of the enclosure if necessary.

2. Remove the left or right conduit hole plug from the top of the enclosure by removing its wing nut inside the enclosure.

Save the hole plug for a later step.

3. Insert the power wires through the left conduit hole on either the top or the bottom of the sign.

TIP

Use watertight conduit connectors only. Flexible conduit should be used.

Internal serial wires

Insert the power wires into one of

Internal wiring for power supply

these conduits.

4. Strip the wires back 6.35 mm (1/4 in.). Connect the incoming electrical wires.

TIP

Be sure to place the wires so they are not caught by screws when replacing the power supply cover, and also so they do not interfere with fan operation.

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.

2706-P42, 2706-P43, 2706-P44, 2706-P72, and 2706-P74 Displays

These displays operate at 100 to 240V ac. They have an eight position terminal block that contains an auxiliary +5V dc, RS-232 signals, and RS-485 signals. There is also an RJ-12 port that is in parallel with the RS-232 signals from the terminal block. The RJ-12 port is used primarily for downloading messages to the display via the 2706-PCABLE1 download cable.

2706-P22 Display

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.

Dip Switch Information for the 2706-P9x

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

2706-P9x Dip Switch

Switch 1

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

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.

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.

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.

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 Protocol

Chapter

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

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.

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.

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 .

Return

Publication 2706-UM016D-EN-P - March 2006

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.

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.

ASCII Message Frame Format

Beg of Frame

: 2-char

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, 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 (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

Examples of Modbus ASCII Functions

Transmitted as 70

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.

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.

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 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

Publication 2706-UM016D-EN-P - March 2006

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), 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 (0xC8) for each message.
