Introduction
1
Chapter
This chapter lists what you need to get started and includes a brief
description of the PCMCIA-FBUS card and the NI-FBUS software.
What You Need to Get Started
To install your NI-FBUS software, you need:
❑ PCMCIA-FBUS card
❑ PCMCIA-FBUS cable
❑ Installation disks
❑ Windows NT version 3.51 or 4.0 installed on your computer
Hardware Description
The PCMCIA-FBUS is a Type II PC card that handles communication
between a PCMCIA-compatible computer and one or more
network-configurable devices that comply with the Fieldbus Foundation
H1 specification. The PCMCIA-FBUS uses the Intel 386EX embedded
processor, shared memory, and an interrupt to communicate with its
driver. The PCMCIA-FBUS supports the fieldbus transfer rate of
31.25 kb/s.
The single-port PCMCIA fieldbus interface is called the PCMCIA-FBUS
and the dual-port PCMCIA fieldbus interface is called the
PCMCIA-FBUS/2. In this manual, the term PCMCIA-FBUS refers to
both the single-port PCMCIA-FBUS card and the dual-port
PCMCIA-FBUS/2 card, unless otherwise indicated.

Chapter 1 Introduction
PCMCIA-FBUS for Windows NT 1-2 © National Instruments Corporation
Software Description
Your kit includes either the NI-FBUS software or NI-FBUS Configurator
software. The NI-FBUS software for Windows NT is a high-level API
you can use to interface with the National Instruments FOUNDATION
Fieldbus (FF) communication stack and hardware. NI-FBUS hides the
low-level protocol details of interface boards, Virtual Communication
Relationships (VCRs), connections, addresses, and Object Dictionary
(OD) indices. NI-FBUS interfaces to the Fieldbus Messaging
Specification (FMS) for you so you can use fieldbus communication
protocols with only a general knowledge of the fieldbus architecture. For
a description of the NI-FBUS Configurator, refer to the Optional
Fieldbus Network Tools section later in this chapter.
The NI-FBUS software and NI-FBUS Configurator software include the
following components:
• NI-FBUS process executable file
• Binary image of the Fieldbus Foundation communication stack
• NI-FBUS Configuration utility
• Windows NT kernel mode driver
The NI-FBUS software also includes the following components not
included with the NI-FBUS Configurator software:
• Windows Dynamic Link Libraries (DLLs)
• Static library for linking with the NI-FBUS process
• NI-FBUS Dialog utility
• C language include files
Note: Because of some bug fixes and specification changes, the
communication stack that NI-FBUS uses is not compatible with the
communication stack in a Round Card using a National Instruments
Device Developer Kit Release older than Version 2.0. If you are using
National Instruments Round Card software older than Version 2.0, you
need to upgrade your software to Version 2.0. Contact National
Instruments for ordering information.

generate the schedule for the network, and can configure field devices
and hosts to transmit and receive alarms and trends. If you have not
already ordered the NI-FBUS Configurator, contact National Instruments
for availability information.
BridgeVIEW helps you perform data acquisition and analysis, create a
man-machine interface (MMI), or develop an advanced supervisory
control application in a graphical development environment.
BridgeVIEW includes real-time process monitoring, historical trending,
alarm and event reporting, online configuration, and PLC connectivity.
To order BridgeVIEW, contact National Instruments.
Lookout helps you create graphical representations on a computer screen
of real-world devices such as switches, dial gauges, chart recorders,
pushbuttons, knobs, sliders, and meters. After linking these images to
your field instruments, you can configure Lookout to generate alarms, log
data to disk, animate custom graphics, print reports, automatically adjust
setpoints, historically trend information, warn operators of malfunctions,
and so on. To order Lookout, contact National Instruments.

2
Chapter
This chapter contains instructions on how to install your PCMCIA-FBUS
card.
Warning: Before you remove the card from the package, touch the antistatic plastic
package to a metal part of your system chassis to discharge electrostatic
energy, which can damage several components on your PCMCIA-FBUS
card.
Install the Hardware
To install the PCMCIA-FBUS card, complete the following steps:
1. Power off your system. Windows NT requires that you power off
your system before inserting the PCMCIA card.
2. Insert the card into a free PC Card (PCMCIA) socket. The card has
no jumpers or switches to set. Figure 2-1 shows how to insert the
PCMCIA-FBUS and how to connect the PCMCIA-FBUS cable and
connector to the PCMCIA-FBUS card. However, the
PCMCIA-FBUS/2 card has two connectors. Refer to Appendix B,

Chapter
This chapter contains instructions on how to install and configure your
NI-FBUS software for Windows NT.
Evaluate the Default Settings
After you have installed the hardware, you are ready to install your
NI-FBUS software. However, you must evaluate the default settings for
your NI-FBUS software before you install the software. Table 3-1 shows
the default settings for the NI-FBUS software.
Table 3-1. NI-FBUS Software Default Settings
NI-FBUS Software Setting Default
Memory Base Address (hex) D0000
Interrupt Line (IRQ) 11
The NI-FBUS software default settings are suitable for most PCMCIA
systems. However, if these default settings conflict with another device in
your system, you must locate conflict-free resources.
To select conflict-free resources, you can use the Microsoft utility
Windows NT Diagnostics, which displays a list of the I/O port addresses,
interrupt levels, and DMA channels that are currently being used in your
system. Assign resources this utility does not list to your fieldbus
interface.
If you cannot find a free IRQ line, you can configure the PCMCIA-FBUS
card to operate in polled mode, without an IRQ line. In polled mode,
NI-FBUS polls your board periodically.

Chapter 3 Software Installation and Configuration
PCMCIA-FBUS for Windows NT 3-2 © National Instruments Corporation
Install the Software
Caution: If you reinstall the NI-FBUS software over an existing version, you lose
any existing board and port configuration information. Before you
reinstall the NI-FBUS software, write down your board configuration.
Also, if you changed any port configuration parameters from their
defaults, write down the new parameters.
Complete the following steps to run the software installation program for
either the NI-FBUS or NI-FBUS Configurator software:
1. Log in as Administrator or as a user that has Administrator
privileges.
2. Insert installation disk 1 into an unused drive.
3. In the Run... dialog box, type the following:
x :\setup
where x is the letter of the drive containing the disk (usually aor b).
The interactive setup program takes you through the necessary steps
to install the software.
By default, the installation program installs the software into the
nifbus default directory. You can change this directory if you want
to install the NI-FBUS software into a different directory.
The installation program copies nifb.dll and drvintf.dll into
your Windows directory, and it copies the nifb.sys kernel mode
driver into the drivers directory. The installation program also
adds information to the Windows NT Registry.
After it copies the software components to the appropriate
directories, the installation program starts the NI-FBUS
Configuration utility. Proceed to the next section, Configure the
NI-FBUS Software.

Chapter 3 Software Installation and Configuration
© National Instruments Corporation 3-3 PCMCIA-FBUS for Windows NT
Configure the NI-FBUS Software
When you install the NI-FBUS software, the installation program starts
the NI-FBUS Configuration utility.
Configure the Base Address and IRQ
To add, view, or change your base I/O address or IRQ settings, complete
the following steps:
1. In the NI-FBUS Config window, select the icon of the board you
want to change and click on the Edit button. If you are adding a
board, click on the Add a Board button.
2. Choose PCMCIA as the Bus Type. The NI-FBUS Configuration
utility displays the default base address and IRQ line.
3. Change the default settings if they do not match the settings on your
board. Set the base address and IRQ line to the conflict-free
resources you found for your PCMCIA-FBUS.
If you want to configure your PCMCIA-FBUS to operate in polled
mode (without interrupts), select a valid IRQ line from the IRQ
drop-down list and check the Polled Mode checkbox. You must
enter a valid IRQ for the PCMCIA card in polled mode because of
the behavior of the Microsoft PCMCIA driver for Windows NT.
NI-FBUS does not actually use an interrupt line in polled mode, but
you still have to enter a valid IRQ.
4. Select the number of ports that matches your PCMCIA-FBUS. For
example, select 2 ports for the PCMCIA-FBUS/2.
Configure the Fieldbus Communication Parameters and Interface
Name You must assign a unique address and a unique physical device tag to
each of your fieldbus interfaces. Your interface must be at a fixed address
or a visitor address for you to start using NI-FBUS.
To assign addresses and tags using the NI-FBUS Configuration utility,
click on the port you want to edit, and click on the Edit button. The
NI-FBUS Configuration utility displays the default logical interface name
and some configuration information. Change these settings if necessary.

Chapter 3 Software Installation and Configuration
PCMCIA-FBUS for Windows NT 3-4 © National Instruments Corporation
If you want to assign a fixed address to your fieldbus interface, choose
Fixed Address and enter a value in the range 0x10 to 0xF7. If you want
your interface to be a temporary device that you do not intend to connect
to the fieldbus for an extended time, choose Visitor Address. If you want
a fieldbus network configuration utility to assign an address to your
interface over the fieldbus, choose Default Address.
Enter a unique tag at the Device Tag prompt. You may leave this empty
if you have set the address to Default Address and you want a fieldbus
network configuration utility to assign a tag over the fieldbus.
NI-FBUS assigns default values for other communication parameters.
Click on the Advanced button to view or change these parameters.
You do not have to reenter these configuration parameters every time you
power up your PC because NI-FBUS saves them. NI-FBUS also saves
changes made to these parameters over the fieldbus.
Configure the Link Active Schedule File
If you are using the NI-FBUS Configurator, you should not configure the
Link Active Schedule file; continue to the next section, Using the
NI-FBUS Configuration Utility after Installation. Or if you do not want
to do scheduling or use publishers and subscribers, continue to the next
section. If you want to do scheduling and use publishers and subscribers,
you must configure the Link Active Schedule file. Refer to Appendix A,
Configuring the Link Active Schedule File, in the NI-FBUS User Manual
for Windows NT, and then test the NI-FBUS software installation, as
described in the Test the Installation section later in this chapter.
Using the NI-FBUS Configuration Utility after Installation
You should use the NI-FBUS Configuration utility after installation in the
following cases:
• To add or remove a fieldbus interface
• To change the software settings to match your physical hardware
settings
• To view or change your software configuration settings

Chapter 3 Software Installation and Configuration
