C reated: December 2002
The Allen-Bradley 1784-PKTX card is a PCI version of the KT communication card. This Tech
Note shows you step-by-step how to configure the 1784-PKTX card with the Wonderware®
AB1784KT I/O Server. The current version of the AB1784KT I/O Server (7,5,0,4) supports the
AB1784 PKTX card.
Requirements
Before you begin, make sure you meet the following requirements or have the following items:
- Windows NT 4.0 with Service Pack 6a or Windows 2000.
- 1784-PKTX card.
- Release 7.5.0.4 or greater of the AB1784KT I/O Server.
Note 1: Firmware files may no longer be included with the PKTX Card. Please contact Rockwell
software for a copy of them. If you install RSLinx and configure the AB1784 PKTX/D/DH+
driver, the bin files for the PKTX card should already be installed on your hard drive. Just do a
search for KTX*.bin. Then, point the AB1784 KT I/O Server to that directory. More information
on how to configure this will be provided later in this technote.
Note 2: For upgrades of existing KT/KTX cards, we suggest that you note your current
settings in the topic definitions (that is, PLC/SLC node addresses and topic names) then
uninstall the current AB1784KT I/O server. Then delete any remaining AB1784KT.* files before
proceeding.
Usability Issues
Wonderware has identified usability issues concerning the PKTX card in certain manufactured
personal computers and motherboards. The issue lies in the securing of memory base addresses
required for the I/O Server to operate.
It has been observed that on certain personal computer brands, in particular, DELL OPTIPLEX,
there may be some difficulty configuring the AB1784KT I/O Server. For example, when you
attempt to save the adapter card configuration, the system may reboot and not allow you to
save the server configuration. This is due to a memory conflict between the PCI memory
required by our I/O Server, and the on-board video card.
If you notice any unusual behavior similar to the above while configuring the I/O Server on
certain personal computers, in particular, the DELL OPTIPLEX series, contact Wonderware
Technical Support @ 1-800-WONDER1 for more information on how to proceed.
A. Set up and configure the 1784-PKTX card
1. Set the Base Memory Jumper (JP2) on the card to the 32-bit position as displayed in Figure 1.

Configuring the AB1784KT I/O Server With the PKTX Card
Note: The PKTX User's Guide recommends that you set the jumper setting to the 32-bit
position when using Windows 95, Windows NT, Windows 2000. Wonderware has found this to
be consistent with configuring the current version of the AB1784KT I/O Server, (versions
7,5,0,4). In the below diagram, the jumper is set to the 1-Meg position. Move the jumper to
the 32-bit postion, or verify that it is set correctly.
Figure 1. Diagram of the 1784PKTX Card
Set the Card ID Jumper (JP3) based on the number of cards available in the system. In our
example, JP3 is set to a single card with ID #0.
Step 2: Install the bin files from your KTXDIAGS disk that comes with the PKTX card (if they
were included with the PKTX card). If the disk is no longer supplied with the PKTX card, then
contact Rockwell Automation to get a copy. If you have Rockwell's RSLinx installed, try to
locate them on your hdd by doing a search for KTX*.bin. The following example shows the files
needed to configure the AB1784KTX I/O Server.

B. Set up and configure the AB1784KT I/O Server
Part I: W indows 2000 Professional
When you install the PKTX card on a Windows 2000 computer for the first time, the OS will
recognize the PKTX card as "New Hardware" when you log on.
The following dialog boxes open:

3. Click Next.
See below:
4. Leave the first radio button selected as Disable the device. The Add/Remove Hardware
Wizard in the Control Panel can be used to complete the driver installation.
5. Click Finish.
Note: Although the new hardware was not associated with any specific device, you have
established two things:
• You will no longer be prompted for new hardware, and;
• Windows 2000 does recognize this device with no specific label. However, it is available for
applications to use.

Note: for Windows NT, you can continue to configure the AB1784KT I/O Server.
At this point, you are ready to configure the AB1784KT I/O Server.
Part II: C onfiguring the AB1784KT I/O Serv er
1. Start up the AB1784KT I/O Server and select Configure/Adapter Card Settings, then click
New.
The AB1784KT Adapter Card Settings dialog box opens:
Figure 3. The AB1784KT Adapter Card Settings dialog box
2. Type in a name for the 1784-PKTX card in the Card Name listbox or leave it as the default
name of "Wonder0."
Select Allen-Bradley 1784-KTX as the Type. You will see a dialog box window with some
informational messages when you make this selection. Simply acknowledge the messages by
clicking OK.
3. Choose the appropriate Highway Speed. The default is 57.6 K Baud.
Note: If you choose 230.4 K Baud, make sure that the settings in the PLC have been
configured accordingly and that the PLC can communicate at this speed. You may set this in
the PLC either through a DIP switch, software, or both. See the user manual for the PLC for
more information.
4. Click the configure button for the Firmware Loading.
The AB1784KT - Firmware Configuration dialog box opens:

Confirm that Load Firmware and User Supplied are selected. Type in the path of the PKTX
firmware files that was defined in Step 5,
Section A. Click OK to return to the AB1784KT Adapter Card Settings dialog box.
5. Select Enable Terminating Resistor as displayed in Figure 4. Select this only if the 1784PKTX card and node are at the end of the Data Highway Plus network.
6. Select a unique node address from the Card's Highway Address drop-down list box that
does not conflict with the other nodes on the Data Highway Plus network.
7. Leave the Reply Timeout at the default value of three seconds. The PC Bus Specific
Parameters should be grayed out. Click OK to continue.
8. You should then see a dialog box that prompts you to save the adapter card settings to a
specific location. Use the default location by clicking OK. Click OK again on the Adapter Card
Settings window to complete the process.
9. When prompted, restart the computer. This will initialize the adapter card settings in the
AB1784KT I/O Server.
10. Start up the AB1784KT I/O Server and select Configure/Topic Definition, then click New.
The AB1784KT Topic Definition dialog box opens:

11. Type in a meaningful name in the Topic Name listbox (example, plc520e) or use the default
of ABPLC.
12. Accept the value that should already be entered in the Adapter Card Name listbox, which
was entered in Step 2.
13. Select the appropriate PLC device type to communicate with under the PLC Family section.
14. Choose a Connect Type (Local is the default value). Notice that the Connect Type chosen
will update the configuration diagram displayed under the Network Addressing section.
15. Choose the correct DH+ node address (in octal) for the PLC or device under the Network
Addressing section. Remember that all nodes on the DH+ network must be assigned a unique
address.
16. Enter the appropriate value for the Discrete Read Block Size and Register Read Block

17. Click OK when finished and leave the I/O Server running for the next section in the
procedure.
C. Test the AB1784KT I/O Server With the WWClient Utility
Note: The WWClient utility is used to test the DDE communications to an I/O Server. More
information on using WWClient is described in Tech Notes 48 and 132.
1. Start up WWClient and make sure the AB1784KT I/O Server is running.
2. From WWClient, select Connect and type in the following:
o Node - leave this blank or type in localhost for a local/resident connection; otherwise enter
the remote node location.
o Application - type in AB1784KT.
o Topic - type in a topic name that's configured in the I/O Server. In our example we used
PLC520E.)
o Connection Type - Select DDE or IOT (an acronym for Suitelink).
3. Click Done.
4. Select Item and type in the required data in the Item listbox. For our example, we typed in
S:23, which is the "seconds" item of the PLC5's internal clock, and is defined as an Integer type
in the dropdown list box.
5. Click the AdviseEx button to execute the item request from the PLC. A successful
connection will display the item, its constant incrementing value, a time and date stamp and the
quality of the data in Hex, which should be zero. Figure 6 shows the output for a successful
connection from both the AB1784KT I/O Server and WWClient.
