Sysmac Library User’s Manual for EtherCAT N-Smart Series Library (W549)
• For information on the characters that can be used in DirName , refer to Specifications of Supported
SD Memory Cards, Folders, and Files in the software user’s manual.
• Do not cycle the power supply to the E3NW Unit after completion of the restore processing.
• In backup or restore processing, the value of
SdoBusy is TRUE when data objects are being sent.
The value of SdoBusy is FALSE when data objects are not being sent due to the internal processing
of the function block.
• Execution of this function block will be continued until processing is ended even if the value of Exe-
cute changes to FALSE or the execution time exceeds the task period. The value of Done changes to
TRUE when processing is ended. Use this to confirm normal ending of processing.
• This function block executes one EC_CoESDOWrite instruction or one EC_CoESDORead instruc-
tion within the part. Refer to the EC_CoESDOWrite instruction in the instructions reference manual
for the maximum number of instructions that can be executed at the same time.
• An error will occur in the following cases. Error will change to TRUE.
a) The EtherCAT master is not in a state that allows message communications.
b) The slave specified with
NodeAdr does not exist.
c) The slave specified with NodeAdr is not in a state that allows communications.
d) The model specified in the backup file differs from the model of the restore destination device
and NoProductChk is FALSE.
e) The slave is not in a state that allows writing of parameters.
f) The EC_CoESDOWrite instruction exceeded the maximum number of instructions that can be
executed at the same time.
g) SD Memory Card access failed (no SD Memory Card inserted, a file is being accessed, etc.).
Precautions for Correct Use
• Do not execute the same instance while an instance is being executed.
• Do not execute backup for slaves to which parameters are being restored.
• Do not attempt to turn OFF the power supply to the Controller and EtherCAT slaves or stop
the EtherCAT communications until the processing for this function block ends normally or
ends in an error.
• During a restore, do not use the measurement data for the E3NW to control machine opera-
tion.
