Introduction
1
Chapter
This chapter contains an overview of the NI-FBUS Monitor.
NI-FBUS Monitor Overview
The NI-FBUS Monitor is a Win32 application you can use to monitor,
debug, and analyze fieldbus data packets. The NI-FBUS Monitor detects
communication on the bus, capturing data packets that are passed
between fieldbus devices. These packets are time-stamped and displayed
in real time on the NI-FBUS Monitor’s active packet view. The NI-FBUS
Monitor can display data packets in decoded format or in hexadecimal
format. The NI-FBUS Monitor can filter out unwanted data packets at
three levels: the Fieldbus Data Link layer (FDL), the Fieldbus Messaging
Specification layer (FMS), and by fieldbus addresses.
Windows of the NI-FBUS Monitor
The NI-FBUS Monitor has a Multiple Document Interface (MDI). An
MDI window contains many smaller windows open concurrently that
display data from different sources. These smaller windows are called
filter windows. In the NI-FBUS Monitor, some filter windows might
contain previously-captured data, while other filter windows might
capture new data from different buses or the same bus.
Chapter 3, Windows and Menus, lists and describes the windows of the
NI-FBUS Monitor.

Chapter 1 Introduction
NI-FBUS Monitor User Manual 1-2 © National Instruments Corporation
Recommended Minimum Platform
The NI-FBUS Monitor uses a lot of processor time and memory
resources during data captures. Therefore, the recommended minimum
platform for the NI-FBUS Monitor is a 66 MHz 486 processor with 8 MB
of RAM. If you want to run the NI-FBUS Monitor on a slower platform,
see the Improving Performance section in Chapter 4, How to Use the
NI-FBUS Monitor.

Installation and
Configuration
2
Chapter
This chapter contains instructions for installing and configuring your
NI-FBUS Monitor software and your fieldbus interface.
Install the Software
Complete the following steps to run the software installation program:
1. Insert the NI-FBUS Monitor software distribution disk into an
unused drive.
2. Choose Run... from the File menu in the Program Manager
window and type the following command into the dialog box:
x :\setup
where x is the letter of the drive containing the distribution disk
(usually aor b).
The interactive setup program takes you through the necessary steps
to install the software.
Continue to the next section to install the hardware.
Install the Hardware
Warning: Before you remove the card or board 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 fieldbus interface.

Chapter 2 Installation and Configuration
NI-FBUS Monitor User Manual 2-2 © National Instruments Corporation
Evaluating the Default Settings
Skip this section if you are using a PCMCIA-FBUS card and
Windows 95.
Table 2-1 shows the default settings for the AT-FBUS board and the
default resources the NI-FBUS software uses for PCMCIA-FBUS cards.
Table 2-1. Default Settings
Type of Setting Default
Memory Base Address (hex) D0000 (physical)
Interrupt Line (IRQ) 11
The default settings are suitable for most computer systems. However, if
these default settings conflict with another device in your system, or if
you need to install more than one fieldbus interface, you must change the
default settings before you install the interface.
If you have to change the settings, continue to the following sections to
locate resources for your fieldbus interface. If the default settings will
work in your system, skip to the appropriate section to install the
hardware.
To install your PCMCIA-FBUS card, skip to the Installing the
PCMCIA-FBUS Hardware section. To install your AT-FBUS board, skip
to the Installing the AT-FBUS Hardware section.
Locating Conflict-Free Resources
To locate conflict-free resources in Windows NT, you can use a utility
such as Microsoft Windows NT Diagnostics. This utility lists the I/O port
addresses, interrupt levels, and DMA channels that your system is
currently using. The resources that this utility does not list are
conflict-free; you can use them for your fieldbus interface. To use this
utility, double-click on the Windows NT Diagnostics icon in the
Administrative Tools program group.
To locate conflict-free resources in Windows 95, complete the following
steps:
1. To use the Device Manager, select Start»Settings»Control
Panel»System. Click on the Device Manager tab.

Chapter 2 Installation and Configuration
© National Instruments Corporation 2-3 NI-FBUS Monitor User Manual
2. Select the Computer and click on the Properties button. The
Computer Properties dialog box appears. You can use any
resources that do not appear in this window.
If you cannot find a free IRQ line, you can configure your fieldbus
interface to operate in polled mode, without an IRQ line. In polled mode,
NI-FBUS polls your board periodically. When you reach the Configuring
the Software section, you can configure your fieldbus interface to use
polled mode.
When you find acceptable resources, write them down, so you can
configure the hardware and software settings to match. Skip to the
Configuring the Hardware (Optional) section.
Installing the PCMCIA-FBUS Hardware
To install the PCMCIA-FBUS card, complete the following steps:
1. Shut down your operating system and power off your system.
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.

Installing the AT-FBUS Hardware
Install the AT-FBUS
To install the AT-FBUS board, complete the following steps:
1. Shut down your operating system and power off your computer.
Keep the computer plugged in so that it remains grounded while you
install the AT-FBUS board.
2. Remove the top cover or access port of the I/O channel.
3. Remove the expansion slot cover on the back panel of the computer.
4. As shown in Figure 2-2, insert the AT-FBUS board into any unused
16-bit ISA slot with the fieldbus connector sticking out of the
opening on the back panel. It might be a tight fit, but do not force the
board into place.
Figure 2-2. Installing the AT-FBUS Board

5. Screw the mounting bracket of the AT-FBUS board to the back
panel rail of the computer.
6. Check the installation.
7. Replace the top cover or access port to the I/O channel.
8. Connect the AT-FBUS to the fieldbus network.
If you want to make your own fieldbus cable, make sure that it uses
pins 6 and 7 for the fieldbus signals, as specified in the Fieldbus
Standard for Use in Industrial Control Systems, Part 2,
ISA-S50.02.1992. Refer to Appendix B, Pinout Information, to see
the fieldbus connector pinout of the AT-FBUS.
9. Power on your computer.
Skip to the Configuring the Software section.
Configuring the Hardware (Optional)
Follow the instructions in this section if you need to change the hardware
default settings of the AT-FBUS board. Refer to the Evaluating the
Default Settings section at the beginning of this chapter for reasons to
change the default settings of your AT-FBUS board.
Figure 2-3 shows the location of the switches, jumpers, and connector on
the AT-FBUS board.
