Field device can't execute
command: FBM on-line
No
The Type STT terminal cannot
change any transmitter
parameters while field bus is
active.
Transmitter must be brought off-line.
This can be done from the MFC/MFP
module by tuning the function code.
NOTE: To bring transmitter offline, the
FBM can be unplugged from the rack.
Be aware that by doing this, communi-
cation is lost for all other transmitters
on the bus. When FMB is unplugged,
there is a two minute time-out period
until the Type STT terminal will be
allowed to change parameters. After
the two minute period, the transmitter
allows the Type STT terminal access.
Field device can't execute
command: Invalid com-
mand
No
Incorrect syntax.
Wrong transmitter type selected in
configuration.
Excessive line noise.
Check line noise. Use oscilloscope to
determine if line noise is excessive.
Type STT terminal failure.

engaged
No
Unable to configure or cali-
brate.
Hardware lock active. Refer to
Field device can't exe-
cute: Data out of range
Yes
Transmitter sent data that is

Press VIEW key on Type STT terminal
to verify parameters of configuration
and consult appropriate device instruc-
tion for correct parameters.
Field device configuration
does not match STT's
No
Configuration of transmitter
does not exactly match corre-
sponding configuration in
Type STT terminal.
Rerange was executed without updat-
ing Type STT terminal configuration.
Perform GET CONFIG (
).
Field device main elec-
tronics EEPROM failure
Yes
Memory problem.
Remove power from transmitter and
reapply. If error still exists after reset,
replace amplifier assembly (
).
Field device input over
range
No
Input exceeds cell
specification.
Correct process input.
