Make sure that
NI-FBUS

Usage
, unless you will be
using the board in conjunction with the NI-FMON software.
If you are using this interface as a bus monitor, the other interface
(if this is a two-port board) cannot be used for NI-FBUS. This means
that you must have another link master on the link—either another
AT-FBUS board or a device with link master capabilities. Refer to the
Optional Fieldbus Network Tools
for more information.
NI-FBUS assigns default values for other network communication
parameters.
Caution
Do
not
modify the
Advanced
parameters without good reason. If you must
modify parameters for certain devices, the device manufacturer will recommend settings.
Modifying these parameters can have an adverse affect on data throughput rates. If settings
are incorrectly modified, some devices might disappear off the bus.
