Environment and Enclosure

Preface 3

ATTENTION

This equipment is intended for use in a Pollution Degree 2 industrial
environment, in overvoltage Category II applications (as defined in IEC
publication 60664-1), at altitudes up to 2000 meters without derating.

This equipment is considered Group 1, Class A industrial equipment
according to IEC/CISPR Publication 11. Without appropriate
precautions, there may be potential difficulties ensuring electromagnetic
compatibility in other environments due to conducted as well as radiated
disturbance.

This equipment is supplied as “open type” equipment. It must be
mounted within an enclosure that is suitably designed for those specific
environmental conditions that will be present and appropriately designed
to prevent personal injury resulting from accessibility to live parts. The
interior of the enclosure must be accessible only by the use of a tool.
Subsequent sections of this publication may contain additional
information regarding specific enclosure type ratings that are required to
comply with certain product safety certifications.

NOTE: See NEMA Standards publication 250 and IEC publication
60529, as applicable, for explanations of the degrees of protection
provided by different types of enclosure. Also, see the appropriate
sections in this publication, as well as the Allen-Bradley publication
1770-4.1 (“Industrial Automation Wiring and Grounding Guidelines”),
for additional installation requirements pertaining to this equipment.

Preventing Electrostatic Discharge

ATTENTION

This equipment is sensitive to electrostatic discharge, which can cause
internal damage and affect normal operation. Follow these guidelines
when you handle this equipment:

• Touch a grounded object to discharge potential static.

• Wear an approved grounding wriststrap.

• Do not touch connectors or pins on component boards.

• Do not touch circuit components inside the equipment.

• If available, use a static-safe workstation.

• When not in use, store the equipment in appropriate static-safe

packaging.

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.

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.

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.
