Cause and Assumed cause
correction
There is no connection between the
EtherCAT master and the slave (Link
OFF).
An error caused an incorrect Ether-
CAT master status.
The EtherCAT network configuration
information does not agree with the
physical network configuration.
The request to the EtherCAT slave
failed.
The EtherCAT master was temporar-
ily unable to perform the processing
because it was executing other pro-
cessing.
Initialization of the EtherCAT slave
failed.
It was not possible to read the backup
parameters from the EtherCAT slave.

Correction
Wire the EtherCAT master and slave
securely.
Use the Sysmac Studio or the Trou-
bleshooter of an HMI to check for
errors and eliminate any EtherCAT
errors.
Make sure that network configuration
information agrees with the physical
network configuration.
Connect the cable securely. Imple-
ment noise countermeasures if there
is excessive ambient noise. If the situ-
ation does not improve, replace the
EtherCAT slave.
Try backing up the data again.
Connect any slaves that are discon-
nected. Use the Sysmac Studio or the
Troubleshooter of an HMI to check for
the following errors: Slave Initializa-
tion Error, Slave Application Error,
and Process Data Communications
Error. Eliminate any errors that you
find.
The ESI file may be incorrect. Ask the
manufacturer of the slave if you can
read all of the parameters that are set
as backup parameters. If all of the
backup parameters can be read, the
EtherCAT slave is faulty. Replace the
EtherCAT slave.

Prevention
Wire the EtherCAT master and slave
securely and make sure that a con-
nection is established before you
attempt to back up the data.
Back up the data when there are no
EtherCAT errors.
Back up the data only when the net-
work configuration information agrees
with the physical network configura-
tion.
Connect the cable securely. Imple-
ment noise countermeasures if there
is excessive ambient noise.
None
Back up the data when the EtherCAT
slave is participating in the network
and there are no slaves that are dis-
connected from the network. Also,
back up the data when there is no
Process Data Communications Error.
None
