6. Select the Read by Name radio button and enter MANUFAC_ID as
the name. Click Read. Write down the hexidecimal number found
in parenthesis (0xnumber) in TableA-1.
7. Repeat step 6 for the name DEV_TYPE.
8. Repeat step 6 for the name DEV_REV.
9. Repeat step 6 for the name DD_REV.
10. Repeat steps 5 through 9 for each device, then close the NI-FBUS
Dialog utility.
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
