possible solutions.

Table B-1. Fieldbus Communication Problems

Problem Solutions

FP-3000 is not visible on the

Fieldbus from a host configurator • Is the power LED on? If not, check your power supply and

DC power wiring to the FP-3000.

• Is the Fieldbus network light on? If not, your Fieldbus

wiring is probably 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 Fieldbus host probing the network address of the

FP-3000? If not, the FP-3000 will not be able to get on the

network. Check your host documentation for how to make

the host probe all network addresses. For NI-FBUS, use the

Interface Config program, select Advanced settings for

the interface port, and set Num of unpolled nodes to 0,

then restart NI-FBUS.

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

Configurator to complete setting the address and device tag of

the FP-3000. When the process is complete, the blocks will

show up.

Otherwise, FP-3000 might be stuck at a default network

address with no tag. Consult your host documentation on how

to set the address and device tag.

All the blocks and configuration

information are lost on a power

cycle

Make sure the Reset switch at the back of the FP-3000 is set

correctly. Refer to AppendixA, Configuring the FP-3000, for

details.

FP-3000 does not execute the

communication schedule when it

becomes LAS

You must download a schedule to the FP-3000. If you are using

NI-FBUS Configurator, make sure FP-3000 is in the list of

devices to receive a schedule.
