Allen–Bradley publication SGI–1.1, “Safety Guidelines for the

Application, Installation and Maintenance of Solid State Control”

(available from your local Allen–Bradley office) describes some important

differences between solid–state equipment and electromechanical devices

which should be taken into consideration when applying products such as

those described in this publication.

Reproduction of the contents of this copyrighted publication, in whole or

in part, without written permission of Allen–Bradley Company, Inc. is

WARNING: With any complex communication system you

need to identify potential application–related communication

problems and make provisions in the system design to prevent

hazardous or undesired consequences if a problem occurs.

These problems include, but are not necessarily limited to, the

possibility of:

unexpected loss of communication

erroneous or incomplete data being supplied to the network

and passed on to your application

The 1784-KT2 Communication Interface Module is an IBM PS/2

MicroChannel card that you can insert into any 8- or 16-bit IBM PS/2

expansion slot. The 1784-KT2 provides the following features:

makes your PS/2 computer an active node on Data Highway Plus

provides single cable connection to a PLC-2, PLC- 3, or PLC-5 family

programmable controller

operates with 6200 programming software

is address selectable; you can use with other option boards installed in

your PS/2 computer

when combined with Allen-Bradley 6001-F1E2 software, allows you to

create your own custom interface to Data Highway Plus

The 1784-KT2 has been verified for operation with the following

computers:

Allen-Bradley 6123, 6124

IBM PS/2 7541, 7561, 8550, 8555, 8560, 8570, 8580

The 1784-KT2 allows you to communicate with PLC-2s, PLC-3s, and Data

Highway Plus nodes. The 1784-KT2 conducts the data communication,

management, and local Data Highway Plus diagnostics. The interface to

the personal computer is through board-resident shared memory that passes

preformatted Data Highway Plus packets. Upon powering up the computer

and downloading module code, diagnostics are run automatically to verify

the 1784-KT2’s operation. Allen-Bradley’s 6001-F1E2 software manages

the transmission and reception of data through board-resident shared

memory.

To prepare the IBM PS/2 Reference diskette for 1784-KT2 configuration

capability, you must:

create a backup copy of the IBM PS/2 Reference diskette and the

1784-KT2 Options and Diagnostics diskette

copy the 1784-KT2 Adapter Description file to the backup copy of the

IBM PS/2 Reference diskette

create a backup copy of your PS/2 computer’s current configuration

The following sections provide information on the above procedures.

Creating Backup Diskettes

Before installing or configuring your 1784-KT2, make a backup of the

1784-KT2 Options and Diagnostics diskette that was shipped with your

1784-KT2. Follow IBM instructions for completing this process.

Also make a backup of your most recent version of the IBM PS/2

Reference diskette. In this document, we refer to this backup copy as the

“current” IBM PS/2 Reference diskette. Follow IBM instructions for

completing this process.

After you have created the above backup copies, store the original

diskettes.

Copying the 1784-KT2 Adapter Description File

This section provides information on how to copy the 1784-KT2 Adapter

Description file (60C6.ADF) from the backup 1784-KT2 Options and

Diagnostics diskette to the current IBM PS/2 Reference diskette. You

cannot configure the 1784-KT2 until the Adapter Description file is added

to the current IBM PS/2 Reference diskette.

To copy the Adapter Description file, follow the steps below:

1. Insert the current IBM PS/2 Reference diskette into drive A of your

computer.

This section provides information on installing the 1784-KT2 into an

Allen-Bradley 6123, an Allen-Bradley 6124, or an IBM PS/2 computer.

When installing the 1784-KT2 into a 6123 or 6124, refer to the 6123/6124

User’s Manual (publication 6123-2.1).

Important: Read the IBM PS/2 Model Quick Reference guide before you

install the 1784-KT2. Pay close attention to the section entitled “Installing

Options.”

CAUTION: The 1784-KT2 utilizes CMOS Technology

, which is

highly sensitive to electrostatic dischar

ge (ESD). ESD may be present

whenever you are handling the 1784-KT2. Handling the 1784-KT2

without any ESD protection can cause internal circuit damage that may

not be apparent during installation or initial use. A grounding wrist

strap has been shipped with the 1784-KT2 to be worn during the

installation procedure. Instructions for use of the strap are found on the

back of its package.

The following is a list of precautions to guard against ESD damage:

Before handling the module, be sure to wear the provided static strap

and touch a grounded object to discharge any built-up static charge.

Avoid touching the backplane connector or interface connector pins

located on the 1784-KT2.

If the module is not in use, store the 1784-KT2 in the static bag that the

module was shipped in.

To install the 1784-KT2, follow the steps below:

1. Disconnect the ac power to the computer.

2. Remove the computer’s system-unit cover (according to the

manufacturer’s instructions).

3. Select a vacant 8- or 16-bit expansion slot.

Important: The 1784-KT2 will function in an 8- or a 16-bit

expansion slot only.

4. Remove the rear bracket-slot’s expansion cover by loosening the

screw on the back of the computer.

5. Insert the 1784-KT2 into the edge connector and tighten the

expansion slot screw.

6. Replace the system-unit cover.

7. Connect the ac power to the computer.

You are now ready to configure your 1784-KT2.

Important: We assume you have already made a backup of your IBM

PS/2 Reference diskette and prepared it for 1784-KT2 configuration

capability. If you have not yet done so, refer to the section earlier in this

document.

In the following, [ENTER] indicates when you must press the enter key.

To configure the 1784-KT2, follow the steps below:

1. Insert the current IBM PS/2 Reference diskette into drive A.

Display your selection on the screen. Make sure you select an

interrupt that is not being used by another adapter card in your PS/2

computer.

9. Set the auxiliary communication port by moving the cursor down to

the Auxiliary Communication Port option. This port, one of the

two communication ports available through a single 1784-KT2

connector, is used for communication with a PLC-2 or PLC-3

connected to the 1784-KT2.

The other communication port, the main port, is used for Data

Highway Plus communication when the 1784-KT2 is connected to

the Data Highway Plus network. You do not need to configure the

main port.

The 1784-KT2 supports the following auxiliary port options:

PLC-2/3 Direct Connect Reserved (for future 1784-KT2 auxiliary

port usage)

Use [F5] and [F6] to display “PLC-2/-3 Direct Connect” on your

screen.
