Recovery
For the NX bus of CPU Units
When Fail-soft Operation Is Set to Stop
Restart the NX Unit and then reset the error in the NX Bus Function
Module.

Restart the NX Unit and then reset the error in the NX Unit.
For Communications Coupler Units
When Fail-soft Operation Is Set to Stop
If the errors are detected in the Con
t
roller, restart the NX Unit and
then reset all of the errors in the Controller.
If the errors are not detected in the Controller, restart the NX Unit
and then reset the error in the Communications Coupler Unit.

Cause and
correction
Assumed cause Correction Prevention
For the NX bus of CPU Units
The power supply to the CPU
Unit
was turned OFF while writ-
ing the Unit operation settings
wa
s in
progress. Or there is an
error in the area of the non-vola-
tile memory in the CPU Unit in
wh
ich th
e Unit operation set-
tings for the relevant NX Unit
ar
e sav
ed.
Download the Unit operation
settings of
the
NX Unit again. If
the error persists even after you
make the above correction,
replace the CPU Unit.
Do not turn OFF the power sup-
ply to the CPU Unit while transfer
of the
Un
it operation settings for
the NX Unit or save of NX Unit
parameters by a message is in
progress.
For Communications Coupler Units
The power supply to the Com-
munications Coupler Unit was
turne
d
OFF while writing the
Unit operation settings was in
progress. Or there is an error in
the area of the non-volatile
memory in the Communications
Coupler Unit in which the Unit
operation settings for the rele-
vant NX Unit are saved.
Download the Unit operation
settings of
the
NX Unit again. If
the error occurs again even
after you make the above cor-
rection, replace the Communi-
cations Coupler Unit.
Do not turn OFF the power sup-
ply to the CPU Unit while transfer
of the
Un
it operation settings for
the NX Unit by the Support Soft-
ware or save of NX Unit parame-
ters by a message is in progress.
