Important: When you connect a Data Highway Plus link to a Data Highway II link, you must observe the following limitations:

A computer connected to a Data Highway Plus (through a 1785-KE or

1770-KF2 module) cannot access nodes on a Data Highway II through a 1779-KP5 module.

Nodes on Data Highway II cannot access a computer connected to Data

Highway Plus.

A 1784-T50 on a Data Highway Plus link cannot program devices on

another Data Highway Plus link through the 1779-KP5.

A computer on a Data Highway II, however, can access a PLC on Data Highway Plus through a 1779-KP5.

Chapter 2

Overview of the 1779KP5 Module

You cannot connect nodes to Data Highway Plus links that are part of a bridge configuration. Also, make sure that both 1779-KP5 modules in a bridge configuration assign the same link number to the Data Highway Plus link.

You can also assign a link number to a Data Highway Plus link that is not part of a bridge configuration. This would allow you to address up to 64 nodes on the Data Highway Plus link, instead of the 15 node limitation when you do not assign a link number. If you choose to assign a link number, however, you must also use station-management commands to set communication routes on your network. For more information on addressing, refer to Chapters 4 and 5.

You set the address for a link using switches on the 1779-KP5. For information on how to set the link number on a 1779-KP5, refer to the switch-setting information in Chapter 3.

How the 1779KP5 Routes Messages to Other Data Highway II Links

When you use a 1779-KP5 in a bridge configuration, you must set switches on the module to enable route updates.

When you enable route updates, the 1779-KP5 module sends a route update message onto the network. This update message tells other Series B modules on the network which links are accessible through the 1779-KP5 that sent the message. The route update also specifies the number of “hops” or bridges that a message must travel through to reach each link.

The following example shows a typical bridge configuration example:

Link 10 Link 4 Link 8

1779KP5

Node 20 Node 30

Data Highway Plus

1779KP5

Data Highway IIData Highway II

16486

26

In the previous example, the 1779-KP5 on Link 8 (Node 30) broadcasts a route update to the 1779-KP5 on Link 10 (Node 20). This route update tells Node 20 where to forward all messages bound for Link 8. Node 20 forwards this route update information to any other Series B modules on Link 10. By forwarding the route information, the other Series B modules

Chapter 2

Overview of the 1779KP5 Module

on Link 10 know that in order to reach a device on Link 8, they must route the message through Node 20.

Node 20 also broadcasts its route update message to Node 30. Node 30 broadcasts the message to Series B modules on Link 8. This tells the Series B modules on Link 8 that in order to reach a device on Link 10, they must route the message through Node 30.

Once your system is running, your Series B 1779-KP5 modules (in bridge configuration) will automatically forward route updates to all remote Data Highway II links.

Important: Data Highway II PLC-2 Family interfaces (Cat. Nos. 1779-KP2, -KP2R) and PLC-3 Family Interfaces (Cat. Nos. 1779-KP3, -KP3R) do not currently support communication between Data Highway II links. Data Highway II Asynchronous-Device Interfaces (Cat. Nos. 1779-KFL, -KFLR) and Synchronous-Device Interfaces (Cat. Nos. 1779-KFM, -KFMR) must be Series B, Revision A or later to support communication between Data Highway II links.

1779KP5 Diagnostic Tools

Asynchronous-Device Interfaces and Synchronous-Device Interfaces provide station-management and node-management commands for the network layer. For more information, refer to your 1779-KFM, -KFMR or 1779-KFL, -KFLR documentation.

The 1779-KP5 provides the following types of troubleshooting tools:

LEDs for diagnosing the 1779-KP5. Replaceable circuit boards for testing and repairing the module. Diagnostic counters and status bytes you can access from a computer to

help monitor the performance on your network.

For more information on the 1779-KP5 diagnostic tools, refer to Chapter 6.

Guidelines for Mounting the 1779KP5

This chapter provides procedures for:

Mounting the 1779-KP5 Setting the Data Highway II Node Address for the 1779-KP5 Setting Option Switches on the 1779-KP5 Connecting Communication Cables to the 1779-KP5 Connecting Power and Ground to the 1779-KP5 Powering Up the 1779-KP5

You mount the 1779-KP5 in an enclosure. The temperature of the air at any point directly below the module must not exceed 60 Otherwise, the failure rate of semiconductor devices may increase significantly.

The temperature tends to be higher toward the top of the enclosure. In addition, the following factors affect the temperature in an enclosure:

The Size of the Enclosure (Smaller enclosures heat up faster.) How Much Heat Is Being Dissipated in the Enclosure The Temperature of the Air Surrounding the Enclosure

C (140oF).

Heat dissipation includes not only the heat dissipated through the power supplies for your equipment but also the heat dissipated through input and outputcircuits.

To allow necessary air flow for cooling of components, refer to the example shown in Figure 3.1 and follow these rules:

Provide six inches minimum vertical separation and four inches

horizontalseparationbetweencomponents.

Provide six inches minimum vertical separation between a chassis and

the top or bottom of the enclosure.

Provide four inches minimum horizontal separation between chassis

and to enclosure sides.

If you have excess space in the enclosure, leave it at the top of the

enclosure where the temperature is higher.

Mount wiring ducts, taps, and terminal strips no closer than two inches

from any chassis.

Set these thumbwheels to designate the node address of the 1779-KP5 for both Data Highway II and Data Highway Plus. The top thumbwheel represents the most significant digit (MSD). Set this digit to zero, since the highest address available to a Data Highway Plus node is 077 (octal). The bottom two thumbwheels do not go past the digit seven because the address must be an octal number. Each node on your network must have a unique address.

Important: The 1770-T3 industrial terminal (for the PLC-2) cannot communicate with Addresses 000 through 007 and Addresses 100 through 107 (octal). If you have PLC-2s on your Data Highway II network, you may not want to use these node addresses.

Chapter 3

Installing the 1779KP5 Module

Setting the Option Switches

There are three sets of switches (labeled S-2, S-4, and S-5) on the 1779-KP5 host board. Use the following procedure to access these switches:

CAUTION: Electrostatic discharge can degrade performance or cause permanent damage to the module. To minimize or prevent electrostatic discharge damage, handle the module at a static-safe workstation.

If a static-safe workstation is not available, touch and remain in contact with a grounded object to discharge yourself while handling the module.

1. Make sure that you remove all power to the module. Usually, you

remove power to the 1779-KP5 by locking open the main disconnect switch on your enclosure.

2. Loosen the four fasteners on the front panel of the module. Pull the

removable frame out to the switch-setting position. This exposes the switch assemblies.

You use the set of switches labeled S-5 to set the Data Highway Plus communication rate. You must set both these switches ON (toward the word OPEN) for a communication rate of 57.6 Kbits per second.

Setting the PowerSelection Switch

OPEN

Set both switches ON (toward the word OPEN) for

57.6K baud. Set Switch 1 ON and Switch 2

OFF for 115.2K baud. (This setting can be used only when you are using two modules in bridge mode.)

Before connecting power, make sure the power-selection switch on the power-supply board is set properly by following these steps:

If a static-safe workstation is not available, touch and remain in contact with a grounded object while handling the module.

1. If you are resetting the switch, make sure that you remove all power

to the module. Usually, you remove power to the 1779-KP5 by locking open the main disconnect switch on your enclosure.

2. Loosen the four fasteners on the front panel of the module. Pull the

removable frame out to the switch-setting position. This exposes the power-selection switch on the power-supply board.

3. Set the voltage-selection switch to correspond to the level

(115V/230V) of your AC power source. The module is factory set to 115V AC.

4. Push the removable frame back to the operating position and tighten

the four fasteners on the front of the module. The fasteners must be tight to ensure that AC power is not interrupted by the interlock switch on the power-supply board.

The 1779-KP5 provides a jumper which sets a terminating resistor for Data Highway Plus. If you are using two 1779-KP5 modules in a bridge configuration, set this jumper on each module. The jumper terminates the Data Highway Plus link that runs between the two modules.

Connecting Communication Cables

After you have set the switches and the terminator, you can connect the communication cables necessary for your application.

The following sections provide information for connecting the 1779-KP5 to:

Data Highway II Data Highway Plus 1784-T50 Industrial Terminal

CAUTION: The DHII AUX ACCESS connector on the front panel of the module is for future product enhancement. To help protect this connector from electrostatic discharge, make sure that the conductive cap (shipped with the module) remains on theconnector.

Connecting the Data Highway II and Data Highway Plus

The 1779-KP5 has a connector for the Data Highway II network and a connector for the Data Highway Plus network. You must connect a drop cable from each network to the 1779-KP5 (Figure 3.5).

312

If you have a 1779-KP5R, you must connect a drop cable for each Data Highway II cable system.

The drop cable for Data Highway II is provided with the Data Highway II tap (Cat. No. 1779-XP). For more information on Data Highway II cabling, refer to the Data Highway II Cable Planning and Installation Manual (Publication1779-6.5.7).

Guidelines for Power Distribution A Procedure for Connecting Power and Ground to the Terminal Block

314

PowerDistribution Guidelines

Allen-Bradley power supplies have circuits that suppress electromagnetic interference from other equipment. For installations near particularly bad electrical noise generators, an isolation transformer can provide further suppression of electromagnetic interference from other equipment.

In applications where the AC power source is subject to unusual variations, a constant-voltage transformer can stabilize the AC power source to the interface, thereby minimizing shutdowns.

Chapter 3

Installing the 1779KP5 Module

To provide AC power isolation between the 1779-KP5 and other equipment, connect a separate transformer between the module’s power supply and the AC power source. Connect the:

Transformer primary to the AC source. High side of the transformer secondary to the L1 terminal of the power

supply.

Low side of the transformer secondary to the L2/N terminal of the

power supply.

The 1779-KP5 consumes 50 watts of power. To determine the required rating of the transformer, multiply the power requirements of the Allen-Bradley power supplies by 2.5 and add all other power requirements (input circuits, output circuits). Take into consideration the surge currents of devices controlled by the controller when determining power requirements. The minimum transformer rating requirement for the 1779-KP5 interface is 125 VA.

The 115V AC power supplies on Allen-Bradley modules are designed to shut down whenever the AC line voltage drops below 85V. The power supply allows the interface to resume operation when the line voltage reaches 85V again. The 230V AC power supplies on Allen-Bradley modules shut down at 170V AC.

If the transformer is too small, it clips the peak of the sine wave before the voltage drops below 85 volts. The power supply senses this as a low voltage and shuts down the interface prematurely.

Connecting Power and Ground to the Terminal Strip

1. Make sure that you remove all power to the enclosure. Usually, you

remove power by locking open the main disconnect switch on your enclosure.

WARNING: Do not connect power to the power terminals without first removing power from the enclosure. Otherwise, you may be injured by electrical shock.

The interface is shipped to you with a wire connecting the post to the stationary frame and another wire connecting the post to the GND terminal of the terminal block. When you ground the post on the removable frame, you thereby also ground the stationary frame and the power-supply board.

Follow all applicable codes and standards when you ground the module. Refer to the National Electric Code published by the National Fire Protection Association of Boston for more information. Refer to Article 250 of the code for sizes and types of conductors and methods of safely grounding electrical components.

316

3. Connect the L2/N terminal to the low side of the transformer

supplying the AC power. Then connect the L1 terminal to the high side of the transformer supplying the AC power.

4. Install the terminal cover (supplied with your module) over the

terminal block.

WARNING: Do not leave the terminal block exposed. Otherwise, you may touch these terminals and be injured by an electrical shock.

In this chapter, we provide a description of how to address the following links from a node on Data Highway II:

A Data Highway Plus Link Using Local Link Addressing (Link = 0) Another Data Highway II Link Using Remote Link Addressing

(Link > 0)

A Data Highway Plus Link Using Remote Link Addressing (Link > 0)

The 1779-KP5 does not support Data Highway II time-critical commands because these commands are not supported by Data Highway Plus. The 1779-KP5 rejects time-critical commands and returns an error reply to the initiating node. For more information on error codes, refer to your interface manual and Chapter 6 of this manual.

The 1779-KP5 replies to the following diagnostic commands from a Data Highway II node:

communicating from.

Has a link value of zero.

Important: A computer on Data Highway Plus cannot address a node on a remote link such as Data Highway II.

When you use local addressing to address a Data Highway Plus node, you can only use Addresses 01 through 20 (octal) on the Data Highway Plus link.

When you use local addressing, you use the LINK, NODE, and USER fields to specify the node address.

The LINK value is always zero for local commands.

42

Chapter 4

Addressing from Data Highway II

The NODE value for each Data Highway Plus node is the same as the node address of the 1779-KP5 it is connected to (between 01 and 77 octal). Refer to Chapter 3 for information on setting the node address of a 1779-KP5 using the thumbwheels on the front panel.

For example, if the NODE value of the 1779-KP5 is 50 (octal), the NODE value of each Data Highway Plus node connected to it is also 50.

The USER value is the Data Highway Plus node address. The USER value must be between two and 20 (octal).

The 1779-KP5 reserves USER 01 to identify itself to nodes on Data Highway II. You can still use Data Highway Plus Address 01 (the 1784-T50 default address), but Data Highway II nodes will not be able to communicate to this Data Highway Plus node.

For example, a Data Highway Plus node, Address 15 (octal), connected to the 1779-KP5 at:

LINK

NODE

would have the Data Highway II address:

LINK

NODE

USER

Important: Due to PLC-2 address limitations, the USER value you use when sending a command from a 1779-KP2 does not equal the Data Highway Plus address. For more information, refer to the following section on PLC-2 addressing. If you are using a 1779-KP2 to communicate to Data Highway Plus, make sure that the 1779-KP5 node address is not 00 to 07. The 1770-T3 terminal cannot communicate to these addresses.

The following sections provide guidelines for addressing Data Highway Plus nodes from Data Highway II using local addressing.

43

Chapter 4

Addressing from Data Highway II

Addressing Data Highway Plus from a PLC2

To send a message from a PLC-2 (1779-KP2) on Data Highway II to a Data Highway Plus node, you use the following address format in the communication zone of your ladder-logic program (NNN = Node, UUU = User):

NNN UUU

The 1779-KP2 does not support the network layer. The LINK value is automatically 00 (local link).

The NODE value is the node address of the 1779-KP5 that connects you to the destination Data Highway Plus link (the link that contains the node you want to communicate with).

The PLC-2 USER value is determined differently than for other nodes on Data Highway II. Since a PLC-2 cannot send to Addresses 00 to 07 octal (these addresses are defined by the PLC-2 for processor work area), a PLC-2’s access to other node addresses would be extremely limited (only Stations 10 through 20 octal). To solve this problem, the PLC-2 uses a formula to convert the node addresses. This allows the PLC-2 to access all allowable addresses (02 through 20 octal) on Data Highway Plus.

To determine the PLC-2 USER value of a Data Highway Plus node, add 10 (octal) to the Data Highway Plus address. For example, Data Highway Plus Node 12 (octal) has a PLC-2 USER value of 22:

12 + 10 = 22 (octal)

For more information on addressing a PLC-2 on Data Highway II, refer to the PLC-2 Family Interface (1779-KP2, -KP2R) User’s Manual (Publication 1779-6.5.3).

44

Chapter 4

Addressing from Data Highway II

Addressing Data Highway Plus from a PLC3

To send a message from a PLC-3 (1779-KP3) on Data Highway II to a Data Highway Plus node, you use the following address format in the message instruction of your ladder-logic program (NNN = Node, UUU = User):

:NNN.UUU

The 1779-KP3 does not support the network layer. The LINK value is automatically 00 (local link).

The NODE value is the node address of the 1779-KP5 that connects you to the destination Data Highway Plus link (the link that contains the node you want to communicate with).

The USER value is the Data Highway Plus address of the node you want to communicate with.

For example, a PLC-3 message instruction to read a file from a PLC-5:

with Data Highway Plus Address 012 (octal) connected to the 1779-KP5 with a Data Highway II address of 045

(octal)

would look like this:

MOVE FROM :45.12$E0.10.0.0 TO $N10:0,20

If you are communicating to a PLC-5, you need to send a PLC-5 four-level address instead of a six-level address:

Important: If you use a file value of greater than 15, the value wraps around to zero. For example, a value of 16 specifies File 0, a value of 17 specifies File 1, etc.

You must enter the PLC-5 address in the following address format:

$ E [Major Section] . [File #] . [Element] . [Sub-Element]

If you send a full PLC-3 six-level address to a PLC-5, the PLC-5 will return an error.

Addressing Data Highway Plus from a 1779KFL or 1779KFM Device

To address a Data Highway Plus node from a programmable device connected to a 1779-KFL, -KFLR or 1779-KFM, -KFMR, the device must enter the appropriate LINK, NODE, and USER values in the message packet.

The LINK value is always 00 for local addressing.

The NODE value is the node address of the 1779-KP5 that connects you to the destination Data Highway Plus link (the link that contains the node you want to communicate with).

The USER value is the Data Highway Plus address of the node you want to communicate with.

For example, if you send a message to:

a PLC-5 at Address 13 (octal) on a Data Highway Plus connected to a 1779-KP5 with the Data

Highway II Node Address 16 (octal)

your message packet looks similar to this:

Addressing from Data Highway II

When you send a message from a node on your Data Highway II link to a node on a remote Data Highway II link, you address the node using the LINK, NODE, and USER fields.

Use the LINK field to specify what link the remote node is on. The LINK value of a remote link can be between 1 and 15. You set the link value of a remote link using switches on the remote link’s 1779-KP5 (Chapter 3).

Use the NODE and USER fields the same way as normal Data Highway II addressing. The NODE field specifies the node address on the remote link. The USER field specifies the user on the remote node.

For example, if you want to send a message to:

Addressing a Remote Data Highway Plus Using Remote Addressing

User 1 on a 1779-KFL with Node Address 17 on Remote Link 13

your address fields would like like this:

LINK

NODE

USER

You use remote addressing to communicate with a node on a remote Data Highway Plus link. A remote Data Highway Plus link has a link value greater than zero.

Important: Only Series B Data Highway II modules support communication to a remote Data Highway Plus link. The PLC-2 Family Interface (1779-KP2, -KP2R) and the PLC-3 Family Interface (1779-KP3,

The LINK value is the link value of the remote Data Highway II link to which the Data Highway Plus link is attached. The LINK value of a remote link can be between 1 and 15. You set the link value of a Data Highway II link using switches on the remote link’s 1779-KP5 (Chapter 3).

The NODE value for each Data Highway Plus node is the same as the Data Highway II node address of the 1779-KP5 it is connected to. Refer to Chapter 3 for information on setting the node address of a 1779-KP5 using the thumbwheels on the front panel.

For example, if the NODE value of the 1779-KP5 is 42 (octal), the NODE value of each Data Highway Plus node connected to it is also 42.

The USER value is the Data Highway Plus node address. The USER value must be between 1 and 20 (octal).

The 1779-KP5 reserves USER 01 to identify itself to nodes on Data Highway II. You can still use Data Highway Plus Address 001 (the 1784-T50 default address), but Data Highway II nodes will not be able to communicate to this Data Highway Plus node.

Addressing from Data Highway II

Using a Data Highway Plus Link Number

When you use a Data Highway Plus link number, you can address up to 64 nodes to your Data Highway Plus link.

To use a Data Highway Plus link number to address a Data Highway Plus node, you must:

Not enable the route update messages. This means that your 1779-KP5

can receive route updates, but it cannot send a route update to inform other 1779-KP5 modules on where to find the Data Highway Plus link.

Use station-management commands to send the routes from an

intelligent device on your network to the other 1779-KP5 modules. When your device sends the FIXED ROUTE to all local 1779-KP5 modules, these modules will update the route for all other links on the network. For more information, refer to your 1779-KFL, -KFLR or 1779-KFM, -KFMR documentation.

You use the LINK, NODE, and USER fields to specify the Data Highway Plus node address.

The NODE value of a Data Highway II node is the node address you set on the module using the thumbwheels on the front panel.

The default USER value for all Data Highway II devices is 01. For a 1779-KFL module, the devices will have USER values of 01 and 02.

52

For example, a Data Highway II node, Address 15, connected to a 1779-KFL User 2, would have the address:

Important: The address of the initiating Data Highway Plus node must be between 02 and 20 (octal) so that the reply message can be returned. A computer on Data Highway Plus cannot address a node on a remote link, such as Data Highway II or another Data Highway Plus link.

Chapter 5

Addressing from Data Highway Plus

You can send commands to Data Highway II from Data Highway Plus Addresses 002 through 020 (octal). You may still assign Address 001 (the default address for the 1784-T50) and Addresses 021 through 077 (octal) on your Data Highway Plus network, but these nodes are unable to initiate messages to nodes on your Data Highway II network.

In our examples, we use a 1784-T50 Industrial Terminal and Version 2.2 software to display PLC-5 commands. For more information on how to use Version 2.1 software (or earlier), refer to Appendix B.

When you address a local Data Highway Plus link from another Data Highway Plus link, you are limited to addressing a total of 15 nodes (02 through 20 octal) on a Data Highway Plus link.

The LINK number is always zero for a local link.

The NODE number is the NODE address of the 1779-KP5 that connects the other Data Highway Plus link to Data Highway II.

The USER number is the address of the node on Data Highway Plus.

For example, the following message instruction is an example of communicating from a PLC-5 to a PLC-5 on a remote Data Highway Plus using local addressing. This message instruction reads 1,000 words from a PLC-5, Node 013 on a remote Data Highway Plus link. It reads these

The following sections show these two methods.

Using a Data Highway II Link Number

This method limits you to addressing a total of 15 nodes (02 through 20 octal) on a Data Highway Plus link, but it is also easier to implement.

Important: The address of the initiating Data Highway Plus node must be between 02 and 20 (octal) so that the reply message can be returned. The address of the initiating Data Highway Plus node must be between 02 and 20 (octal) so that the reply message can be returned.

The NODE number is the NODE address of the 1779-KP5 that connects the Data Highway Plus link to Data Highway II.

The USER number is the address of the node on the Data Highway Plus.

For example, the following message instruction is an example of communicating from a PLC-5 to a PLC-5 on a remote Data Highway Plus across a bridge. This message instruction reads 1,000 words from a PLC-5, Node 013 on a remote Data Highway Plus link.

When you use a Data Highway Plus link number, you can address up to 64 nodes to your Data Highway Plus link.

To use a Data Highway Plus link number to address a Data Highway Plus node, you must:

Not enable the route update messages. This means that your 1779-KP5

can receive route updates, but it cannot send a route update to inform other 1779-KP5 modules on where to find the Data Highway Plus link.

Use station-management commands to send the routes from an

1779KP5 Diagnostic Counters

The following sections tell you:

What a Diagnostic Counter Is How to Read Diagnostic Counters What 1779-KP5 Diagnostic Counters Contain

What is a Diagnostic Counter?

A diagnostic counter records an event of interest for debugging the module and for longer term reliability analysis.

Since Data Highway II uses application layer diagnostic counters, the 1779-KP5 does not have diagnostic counters for Data Highway II. However, the 1779-KP5 does have counters for Data Highway Plus.

The diagnostic counters occupy a block of the module’s internal scratch RAM. Most are single byte counters that reset to zero when they overflow.

These counters provide a useful tool for diagnosing problems.

How to Read Diagnostic Counters

To read diagnostic counters, you must issue a Diagnostic Read command. This command can only be sent from a device:

Connected to a Data Highway Plus with an interface module that

supports an asynchronous port.

That can format the diagnostic commands.

Therefore, a PLC user program is unable to initiate a Diagnostic Read command.

Important: The location of the diagnostic counters in a Data Highway Plus module varies:

From module to module. Between revision levels of the same type module.

You must first request the location of these counters by transmitting a Diagnostic Status command to the module. Based on the address returned, you can use the number of the counters which follow as an offset to calculate:

The location of a particular counter. How many counter values you want returned.

67

Chapter 6

1779KP5 Troubleshooting Tools

You can then use this information to format a Diagnostic Read command. The reply from the Diagnostic Read command contains the data stored in the counters.

For more information on the Diagnostic Status and Diagnostic Read commands, refer to the Data Highway/Data Highway Plus Protocol and Command Set Reference Manual (Publication 1770-6.5.16).

1779KP5 Data Highway Plus Diagnostic Counters

The 1779-KP5 stores 28 Data Highway Plus counters in 35 bytes. These counters can only be read from an intelligent device (computer) connected to the same Data Highway Plus as the 1779-KP5. The following table contains a list of 1779-KP5 Data Highway Plus diagnostic counter bytes and what they contain (all two byte counters are read low byte first).

Important: When you manually enter a USER number, the remote station number appears to be incorrectly displayed due to how the 1784-T50 interprets the USER number.

Entering the User Number into the Message Control File

When you use 6200 Series software Version 2.1 (or earlier) to communicate from a node on Data Highway Plus to a:

computer/1779-KFL on Data Highway II node on a remote Data Highway Plus network

you must manually enter the USER number into the message control file.

After you have entered a message instruction, enter the USER number byte into the message control file using the following procedure:

1. Make sure the cursor is not on an instruction, then press [F8] - Data

Monitor.

2. Enter the control block address (for example, N13:0) and press the

ENTER key. The following type of display will appear:

Address N13:0 0000 2728 0064 0407 0064 0000 000B 0002 1000 0400

N13:10 0000

Press a key or enter value. N13:0 = [

The control file is displayed in words, not bytes.

The default radix for the display is in decimal. When you want to change only the single byte for the user number, it is easier to select hex/BCD as the radix of the display.

The USER number always follows the Remote DST address in this file.

4. Use the right cursor [ >] key to move to the word containing the

USER number byte. Enter the USER number (in hex) on the display line, as well as the value for the other byte in the word, and press the [ENTER] key. This changes the value in the specified word to include the USER number.

Important: When you enter the value for the word containing the USER byte, do not change the value of the other byte in the word.

The following screens show the control file during the change and after the change:
