Presumed Cause
Wiring is incorrect.
The power is off or the power
supply voltage is less than 9 V.
The address detection range is
not correctly set.
The fieldbus is experiencing a
large amount of noise.
Missing terminators on the bus,
incorrect terminator placement
or extra terminators. Refer to
FOUNDATION Fieldbus specifi-
cations for a full discussion of
terminator requirements.
The node address of the SVI FF is
left in the default (0xF8-0xFB).
Remedy
Correct wiring.
Supply proper voltage.
Correct address detection
range.
Using an oscilloscope,
check the waveform on the
fieldbus.
Change the device to an
operable address. See the
descriptions for address
settings.
