Introduction  
This chapter lists what you need to get started and includes a brief  
description of the HSE Linking Device and the NI-FBUS software.  
What You Need to Get Started  
To install your NI-FBUS software, you need the following items:  
HSE linking device  
Installation disks  
Ethernet adapter installed on your computer  
Windows 2000/NT/XP installed on your computer  
Hardware Description  
Foundation Fieldbus includes both H1 (31.25 kbit/s) and High Speed  
Ethernet (100 Mbit/s) specifications. HSE Linking Device is a high-speed  
Ethernet (HSE) device used to integrate H1 fieldbus segments into the HSE  
backbone from an Ethernet-based network. The HSE Linking Device  
provides standard UDP/TCP access to H1 field devices.  
Software Description  
Your kit includes either the NI-FBUS Communications Manager software  
or the NI-FBUS Configurator software. Depending on the system you  
purchase, you may receive both disks; if this is the case, you should use the  
NI-FBUS Configurator software.  
The NI-FBUS Communications Manager software is used by the interface  
boards or linking device to communicate over the bus. Additionally, it  
provides a high-level API advanced users can use to interface with the  
National Instruments Foundation Fieldbus communication stack and  
hardware.

Introduction  
Most users use the NI-FBUS Configurator. In addition to providing the  
functionality of the NI-FBUS Communications Manager in a graphical  
format, it includes additional functionality to allow you to configure a  
Fieldbus H1 and/or HSE network. It can automatically generate the  
schedule for the network and configure field devices and hosts to transmit  
and receive alarms and trends.  
NI-FBUS Interface Configuration Utility  
The NI-FBUS Interface Configuration Utility lets you view and change  
the hardware configuration parameters for your Fieldbus interfaces. In  
Windows 2000/NT/XP, you also can edit your hardware configuration  
parameters and add and delete interfaces.  
The NI-FBUS Interface Configuration Utility helps you to configure the  
following information:  
Logical name for each port on your Fieldbus board or linking device;  
you can access the port using the interface name  
Device description information  
Base directory for device description files  
Location of the standard text dictionary  
You need to import device descriptions if you use the NI-FBUS  
Communications Manager to communicate with devices that have  
manufacturer-specific blocks or parameters.  
Fieldbus communication parameters for each Fieldbus interface  
Choosing Configuration Software  
Foundation Fieldbus links must be configured. Only with configuration  
software can you do things like set device addresses, clear devices, and  
download (necessary if you are setting up a system for the first time).  
Your configuration software must match the interface board or linking  
device your computer is using to connect to the bus. National Instruments  
offers the NI-FBUS Configurator with a National Instruments Foundation  
Fieldbus interface board or linking device to let you configure your  
Fieldbus links.  
Interface boards, linking devices and configuration software are sold  
separately because multiple interface boards can reside in the same  
computer and multiple HSE linking devices can be accessed through the  
ethernet network. By default, the NI-FBUS Configurator is licensed for use  
on one machine, with up to four Fieldbus links (segments). If you have  
more than four links (ports on the boards or linking devices), you need to  
HSE Linking Device and NI-FBUS Software

Chapter 1  
Introduction  
purchase a link upgrade for each link in excess of four. To do so, download  
the order form from ni.com/fieldbus.  
Note The connection to one interface port on the interface board or linking devices is  
viewed as one link by the NI-FBUS Configurator, regardless of how many links might  
actually be joined by repeaters. This is important for software licensing of the NI-FBUS  
Configurator.  
If you want to use the board or linking device to read and write values only  
(but not configure) and you are a programmer, you can make calls to the  
API in the NI-FBUS Communications Manager and do not need the  
NI-FBUS Configurator. This is possible only if you already have used  
third-party hardware and configuration software to configure the link.

Installation and Configuration  
Your base directory will include a folder for each different manufacturer for  
which you have imported a device description. For example, if you import  
the device description for the National Instruments FP-3000 device, you  
will find a folder called 4e4943. This is the National Instruments  
Foundation Fieldbus device manufacturer ID number.  
The next layer of folders is the device type. For example, the FP-3000 has  
a device type ID number of 4005.  
Underneath this layer of directories you will find the individual device  
description files (.ffo and .sym).

Starting the NIFB Process  
The NIFB process must be running any time you want to use your  
HSE linking devices as the Fieldbus interfaces to communicate between  
the linking device and the bus.  
On successful startup, the NIFB displays a message confirming successful  
process startup, the title bar of the NIFB window changes to  
NI-FBUS (running), and an icon appears on the Windows taskbar. It may  
take a few minutes for NIFB to start up and this message to display.  
Beginning to Use Your NI-FBUS Software  
If you are using the NI-FBUS Communications Manager, refer to the  
NI-FBUS Communication Manager User Manual for information on using  
your software. If you are using the NI-FBUS Configurator, refer to the  
NI-FBUS Configurator User Manual for information on using your  
software.  
If NI-FBUS is unable to connect to and initialize an interface device,  
and you decide to continue NI-FBUS startup, NI-FBUS will not try to  
reconnect to that interface again. This is true of all interface types supported  
by this software.

Troubleshooting and  
Common Questions  
This appendix describes how to troubleshoot common problems that occur  
while getting started with Fieldbus.  
Error Messages

Appendix A  
Troubleshooting and Common Questions  
Select Start»Programs»National Instruments»NI-FBUS»  
Interface Configuration Utility. Make sure your HSE linking  
device appears under the list of interfaces.  
Make sure your HSE linking device is online.  
When a Fieldbus device is connected to the bus, the NIFB process often  
hangs when the title bar reads Waiting for Startup Completion. If I  
disconnect the cables, it starts properly.  
This is probably due to a device address conflict. In the NI-FBUS Interface  
Configuration Utility, make sure that the interface is not at the same address  
as anything else on the link.  
The NIFB process hangs, does not start up, or never shows that it is  
running.  
The Fieldbus network address is not unique. Remove the cable from  
the HSE Linking device. Restart the NIFB process. If it runs  
successfully, there is probably a Fieldbus network address conflict.  
If you have FP-3000 network modules on the bank, powering them off  
and then back on will cause them to look on the bus for available  
addresses and change addresses if necessary.  
Check for multiple copies of nifb.dll on the machine. If multiple  
copies are found, NI-FBUS was incorrectly re-installed. Uninstall  
NI-FBUS, search for any remaining copies of nifb.dll, delete them,  
then reinstall the software.  
Check how many interface boards are showing up in the Interface  
Configuration Utility. Make sure that this matches the number of  
boards in the system. Also check that the number of ports match the  
physical hardware (one port versus two port boards).  
Interface Configuration Problems  
When using the NI-FBUS Interface Configuration Utility on a  
Windows 2000/NT machine, the error message utility could not  
access or locate the registryappears.  
Make sure you are logged in to Windows with Administrator  
privileges.  
Your registry entries for NI-FBUS may have been deleted or corrupted.  
Uninstall the NI-FBUS software, then reinstall the software as  
described in the Installing the Software section of Chapter 2,  
Installation and Configuration.

Appendix A  
Troubleshooting and Common Questions  
In the Interface Configuration Utility, I see more boards than what  
physically exist in the machine.  
Select Edit for the extra board. In the next window, select Delete.  
Caution You should not attempt to make unguided changes in the Windows Registry.  
Doing so can cause a number of problems with your system.  
Problems Using Manufacturer-Defined Features  
NI-FBUS uses identifying information in the actual device to locate the  
device description for the device. The identifying information includes  
four resource block parameters: MANUFAC_ID, DEV_TYPE, DEV_REV, and  
DD_REV. If the identifying information is incorrect, NI-FBUS will not be  
able to locate the device description for the device. When it has located  
the device description, NI-FBUS matches the block types in the device  
description with the actual blocks in the device by using the Item ID of  
the block characteristics record.  
If the blocks in the device do not match the blocks in the description, or  
if there is no appropriate device description for the manufacturer, device  
type, device revision, and device description revision being returned by  
the device, then there is a device description mismatch. In either case,  
NI-FBUS uses only the standard dictionary (nifb.dct) and you will  
be unable to use any manufacturer-supplied functionality.  
These parameters can be read from the device resource block.  
The following procedure will help you troubleshoot a  
DD_SIZE_MISMATCH_ERROR by finding out if there is a device description  
available on your computer that matches what your device expects.  
Complete the following steps to use the NI-FBUS Dialog utility to check  
device description files.  
1. Start the NIFB process. Wait until the process has finished initializing.  
2. Select Start»Programs»National Instruments»NI-FBUS»  
NI-FBUS Dialog.  
3. Right-click Open Descriptors and choose Expand All.  
4. After the expansion is complete, click Cancel to close the Expand All  
window.  
5. Right-click the resource block for your device. It should be under  
Open Descriptors»Session»Interface Name»Device Name»  
VFD Name»Resource Block Name. Select Read Object.

11. In the Interface Configuration Utility, click DD Info. Write down the  
base directory specified for device descriptions. Close the Interface  
Configuration Utility.  
12. Use Windows Explorer to view the contents of the base directory  
specified in the Interface Configuration Utility. The Fieldbus  
specification defines the directory hierarchy for storing device  
descriptions. There is a different subdirectory for each device  
manufacturer. Under the base directory, you should see a directory  
with the number from step 6 for the first device.  
13. Under the appropriate manufacturer directory, there is a directory for  
each device type that you have from that manufacturer. Check to make  
sure that you see a directory with the number from step 7.  
14. Under the appropriate device type directory, there are individual device  
descriptions. The device description file name is a combination of the  
device revision (the number from step 8) and the device description  
revision (the number from step 9). The device revision is the first two  
digits, and the device description revision is the second two digits. For  
example, if your number from step 8 was 2 and from step 9 was 1, you  
should see files called 0201.ffo and 0201.sym. Device descriptions  
are backward compatible. This means that instead of seeing 0201, you  
might see 0202. This is allowed by the Fieldbus specification. Also,  
having additional files in this directory is not a problem. The NI-FBUS

Troubleshooting and Common Questions  
Configurator will use the most recent device description revision for  
a given device revision. If you do not have the appropriate .ffo  
and .sym files, you must obtain them from the device manufacturer.  
Be sure to import them properly by clicking DD Info and using the  
Import DD button in the Interface Configuration Utility.  
15. Repeat steps 12 through 14 for each device.  
The second cause for this problem is when the contents of the file do  
not accurately describe the device characteristics, even if the device  
identification information matches the file identification information.  
This problem is caused when a device manufacturer makes a change  
to the firmware of the device without incrementing the device revision,  
in violation of the Foundation Fieldbus recommendation. If this is the  
case, you must contact your device manufacturer for a resolution.  
Uninstalling the Software  
To uninstall your NI-FBUS software, select Start»Settings»Control  
Panel»Add/Remove Programs.  
If you are only using the Communications Manager, select NI-FBUS  
Communications Manager to uninstall. If you are using the NI-FBUS  
Configurator, select NI-FBUS Configurator.  
The uninstall utility does not remove the NI-FBUS directory itself or any  
files in the \Data\Nvm directory. To completely uninstall the software,  
manually remove the files in the \Data\Nvm directory and the NI-FBUS  
directory structure.
