Sysmac Library User’s Manual for EtherCAT N-Smart Series Library (W549)
 Timing Chart for Error End
• An object list is binary data that stores, by the revision number of EtherCAT slaves, SDO parameter
information (Index, Subindex, and Complete Access) for the backup target parameters.
• 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.
• 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_CoESDORead instruction within the part. Refer to the
EC_CoESDORead 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) No object list file exists.
b) The EtherCAT master is not in a state that allows message communications.
c) The slave specified with
NodeAdr does not exist.
d) The slave specified with NodeAdr is not in a state that allows communications.
e) The slave is not in a state that allows reading of parameters.
f) The EC_CoESDORead 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, write protection enabled, etc.).
Precautions for Correct Use
• Do not execute the same instance while an instance is being executed.
• Do not execute restore for slaves from which parameters are being backed up.
• Do not change the names and the contents of any object list.
• 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.
