Introducing the Network Interface Cards

Rockwell Automation 1784-PKTx family PCI cards connect PCs to PLC controllers on Data
Highway Plus (DH+) or SLC processors on DH-485 networks for easy programming and
data acquisition. I/O scanner functionality is also available in the cards so they can be used
with soft-control or embedded-control engines. And, because these cards incorporate the
Universal PCI Card Standard, they are compatible with almost any PC. If general
programming, configuration, and monitoring capabilities via an industrial or desktop PC are
required, these cards are a necessity.

Your 1784-PKTx network interface card (cat. nos. 1784-PKTX and 1784-PKTXD) is a PCI
(Peripheral Component Interconnect) universal card that must be inserted into a PCI bus
slot. A universal card can be placed into a PCI bus slot that is keyed for either 3.3 Volt or 5
Volt signalling. This card may also be placed in a 64-bit slot, although it will not use the
extended 64-bit operation.

How the 1784-PKTx Card Operates

The 1784-PKTX and -PKTXD cards:

• communicate with nodes on Data Highway Plus networks, including PLC-5®,
PLC-5/250, and SLC 5/04 processors, and SLC 5/01,
SLC 5/02, and SLC5/03 processors (only via 1785-KA5)

• communicate with SLC processors on DH-485 networks

• communicate to DH+ and Remote I/O via SoftLogix-5

• communicate to ControlLogix through a 1756-DHRIO module

• act as a remote I/O scanner

The 1784-PKTx performs data transmission, management, and local network diagnostics.
The interface to the host processor is through a board-resident dual-port memory.

Rockwell Automation RSLinx interface software manages data transmission and reception
through dual-port memory.

The PCI BIOS on your computer automatically assigns the PKTx card’s IRQ and base
memory address (one for each channel). If your card has two channels, both channels share
the same IRQ.

Publication 1784-UM527B-EN-P - October 2003

Chapter

Configuring the PKTx Hardware

Introduction

The 1784-PKTx card is a PCI bus card, compliant with the PCI Bus Specification Revision

2.3. This card was developed with Plug and Play functionality, as defined in Revision 1.0A of
the Plug and Play BIOS Specification. Because of this, PKTx cards do not require the use of
switches or jumpers to configure their specific interrupt request levels (IRQ) and base
memory address values. These configurations are automatically assigned to the PKTx card by
the PCI BIOS when the computer is powered-up. The configurations are stored in the PCI
configuration registers. These values may be retrieved by application software used to
communicate with the PKTx card.

Interrupt Request Assignment

The PCI BIOS automatically assigns the PKTx card an IRQ. Because of this, each time you
add or remove cards and restart your computer, the BIOS may assign a different IRQ to each
card. You should check the IRQ assignment each time you start your system. Most
application software will verify this assignment for you. If you’re using RSLinx, its Plug and
Play driver verifies the IRQ.

Base Memory Address Values

Although the assignment of the IRQ and base memory address values is automatic, and does
not require user intervention, there is one jumper on the PKTx card that is used to restrict the
range of values that can be assigned to the base memory address by the PCI BIOS. This
jumper is called the Base Memory Address jumper, and its default position is set to 32 bit.

you are not using Microsoft Windows 95 or later, you may have to set this jumper. See

If
Figure 2.1 on page 2-2.

Publication 1784-UM527B-EN-P - October 2003

Figure 2.1 Overview of the jumpers on the PKTx card

Base Memory
Jumper (JP2)

Card ID Jumper (JP3)

Setting a Base Memory Address Jumper

The host computer and the PKTx card exchange data via a dual-port interface. The dual-port
requires 4 Kbytes of memory. This 4 Kbyte block of memory begins at the base memory
address assigned to the card by the PCI BIOS when the computer is started.

Under MS-DOS, Windows 3.1 and Windows for Workgroups, the base memory address of
PC cards should fall within the range of 0 and 1 Megabyte of PC memory. For the newer
Windows operating systems, this restriction is no longer required, and the base memory
address should be located anywhere in the PC memory space.

The Base Memory Address jumper (JP2) forces the PCI BIOS to assign the base memory
address to one of two address ranges, as shown in the table below. You should select the
jumper position based on the operating system running on your PC.

Using Multiple PKTx Cards

It is possible to have more than one PKTx card within your system. You can have up to four
cards functioning at the same time. There are two jumpers that can be set to establish unique
identification between the PKTx cards. The position and combination of the two jumpers
allow each card to be uniquely recognized by any application software.

The default position, card ID 0, has both jumpers in place.

Publication 1784-UM527B-EN-P - October 2003

2-4 Configuring the PKTx Hardware

Planning Jumper Settings for Multiple Cards

Located on each PKTx card is a set of jumpers with markings that indicate how each jumper
can be set. These jumpers are identified as JP3. It is important to coordinate the setting of
these jumpers so that each card can be recognized by the system.
below show possible combinations of jumper settings that can be used if you have a total of

You must terminate the last physical node of the network with a resistor
of appropriate value.

If all of the devices on your network are capable of operating at 230.4K,
use an 82
resistor.

Connecting the Card via a DH-485 Network

Figure 4.1 shows an example of a network consisting of three SLC family controllers and one
programming station. This configuration requires the 1784-PKTX or -PKTXD card and
three link couplers:

• An SLC family CPU is connected to each of the link couplers (1747-AIC) with a
1747-C11 cable.

• The 1784-PKTX or -PKTXD card is connected to the network at one of the link
couplers, as shown in Figure 4.1.

• The communication cable consists of three segments of cable daisy-chained at each
link coupler.

Connecting the Card to a Single SLC Processor on DH-485

Figure 4.2 on page 4-10 shows an example of a point-to-point link consisting of an SLC
processor and a programming station. This configuration requires the 1784-PKTX or

-PKTXD card and an SLC processor. The SLC CPU is connected directly to the 1784-PKTX
or -PKTXD card with a 1784-CP14 cable, as shown on

page 4-10.

Terminating the Last Node

You must terminate both ends of your DH-485 network. If the PKTx is the last node on
your network, you must set the switch on the CP14 to terminate the link as shown below.

Connecting to Remote I/O Devices

Depending upon your application, you can use the PKTx card to communicate with a single
device or to multiple devices via a remote I/O link.

To connect the PKTx card to remote I/O, use Allen-Bradley 1770-CD or approved cable to
construct a custom cable. See publication ICCG-2.2 for a list of approved cables.

IMPORTANT

For proper operation, terminate both ends of a remote I/O link by
using external resistors. Use either an 82Ω or 150Ω terminator.
See Table 4.1.

Interpreting the Status LEDs

What the LEDs mean depends on which protocol is running. Only the PKTXD uses both
LEDs. The left LED (labeled |) is for the top channel on a PKTXD and the other is for the
second, lower channel. A PKTX has only one channel (but multiple connectors depending on
protocol) so only one LED is used.

Table 4.2 explains the DH+ Status LED. Table 4.3 on page 4-13 explains the DH-485 Status
LED. Table 4.4 on page 4-13 explains the Remote I/O Scanner Mode LED.
