possible solutions.

Table F-1. Fieldbus Communication Problems

Problem

Solutions

FP-3000 is not visible on the
Fieldbus from host configuration
software.

Is the power LED on? If not, check your power supply and
DC power wiring to the FP-3000.

Is the Fieldbus network LED on? If not, your Fieldbus
wiring could be bad.

Check the switches on the back of the FP-3000. Make sure
the Reset switch is not On. Refer to Appendix A,

Configuring the FP-3000

, to view a diagram of the

configuration switches.

Is your host configuration software probing the Fieldbus
network address of the FP-3000? If not, the FP-3000 will
not be able to get on the network. Check your host
configuration software documentation for how to make the
host probe more or all network addresses. For NI-FBUS,
one way to do this is to use the Interface Config program,
select Advanced settings for the interface port, and set
Num of unpolled nodes to 0, then restart NI-FBUS. Refer
to the NI-FBUS Configurator User Manual for other
options and a discussion of the ramifications of setting
Num of Unpolled Nodes to 0.

FP-3000 NETWORK LED is
red (steady or flashing).

Check your Fieldbus wiring for short circuits or other electrical
problems.

FP-3000 is visible on the
Fieldbus from a host, but no
blocks show up.

If you are running NI-FBUS Configurator, and this is your first
startup of FP-3000, wait a couple of minutes for the NI-FBUS
Configurator to complete setting the device and address tag of
the FP-3000. When the process is complete, the resource block
will show up and you can instantiate (create) other blocks
either using the autoconfiguration function or manually.

Otherwise, the FP-3000 might be stuck at a default Fieldbus
network address with no tag. Consult your host configuration
software documentation on how to set the address and device
tag.
