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 the 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 backwards 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 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 properly import them by clicking
on DD Info and using the Import DD button in the Interface
Configuration utility.
15. Repeat steps 12–14 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 F
O U N D A TIO N Fieldbus recommendation. If this is the case,
you must contact your device manufacturer for a resolution.
