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.

3. After you finish setting switches, 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.

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.
