Cause and It was not possible to write the backup
correction parameters to the EtherCAT slave.
Incorrect backup data was detected.
The EtherCAT network configuration
in the backup data does not agree
with the physical network configura-
tion.
An error occurred at an OMRON
Communications Coupler Unit.
The following causes are possible.
• Reading a backup file failed at the
Communications Coupler Unit
(when attached information 4 is 1).
• Communications with the Commu-
nications Coupler Unit or NX Unit
failed (when attached information 4
is 2).
• The Unit Configuration of the NX
Units in the Communications Cou-
pler Unit when data was backed up
did not agree with the actual config-
uration of NX Units (when attached
information 4 is 3).

The ESI file may be incorrect. Ask the
manufacturer of the slave if you can
write all of the parameters that are set
as backup parameters. If all of the
backup parameters can be written,
the slave is faulty. Replace the slave.
Format the SD Memory Card with the
Sysmac Studio and then place the
backup file on it.
Make sure that the EtherCAT network
configuration in the backup data
agrees with the physical network con-
figuration.
• Try backing up the data again
(when attached information 4 is 1).
• Connect the cable securely.
• Mount the NX Unit securely.
• Implement noise countermeasures
if there is excessive ambient noise.
• If the problem still exists, replace
the Communications Coupler Unit
or the NX Unit (when attached infor-
mation 4 is 2).
• Make the Unit Configuration of the
NX Units in the Communications
Coupler Unit when data was
backed up agree with the actual
configuration of NX Units (when
attached information 4 is 2 or 3).
• Correct the hardware switches on
the Communications Coupler Unit
so that they are the same as when
the data was backed up (when
attached information 4 is 3).

None
Do not remove the SD Memory Card
or turn OFF the power supply while
the SD BUSY indicator is lit. Or,
replace the SD Memory Card periodi-
cally according to the write life of the
SD Memory Card.
Make sure that the EtherCAT network
configuration in the backup data
agrees with the physical network con-
figuration before you try to restore the
data.
• Format an SD Memory Card with
the Sysmac Studio and then place
the backup file on it.
• Also, do not remove the SD Mem-
ory Card or turn OFF the power
supply while the SD BUSY indicator
is lit (when attached information 4 is
1).
• Connect the cable securely.
• Mount the NX Unit securely.
• Implement noise countermeasures
if there is excessive ambient noise
(when attached information 4 is 2).
• Restore the data while the Unit
Configuration of the NX Units in the
Communications Coupler Unit
agrees with the actual configuration
of NX Units (when attached infor-
mation 4 is 2 or 3).
• Restore the data while the hard-
ware switches on the Communica-
tions Coupler Unit are the same as
when the data was backed up
(when attached information 4 is 3).
