Restoring the delivery state

To restore the delivery state (factory settings) of CoE objects for EtherCAT devices ("slaves"), the CoE object
Restore default parameters, SubIndex 001 can be used via EtherCAT master (e.g. TwinCAT) (see Fig.
Selecting the Restore default parameters PDO).
Fig. 175: Selecting the Restore default parameters PDO
Fig. 176: Entering a restore value in the Set Value dialog
Double-click on SubIndex 001 to enter the Set Value dialog. Enter the reset value 1684107116 in field Dec
or the value 0x64616F6C in field Hex (ASCII: "load") and confirm with OK (Fig. Entering a restore value in
the Set Value dialog).
• All changeable entries in the slave are reset to the default values.
• The values can only be successfully restored if the reset is directly applied to the online CoE, i.e. to the
slave. No values can be changed in the offline CoE.
• TwinCAT must be in the RUN or CONFIG/Freerun state for this; that means EtherCAT data exchange
takes place. Ensure error-free EtherCAT transmission.
• No separate confirmation takes place due to the reset. A changeable object can be manipulated
beforehand for the purposes of checking.
• This reset procedure can also be adopted as the first entry in the startup list of the slave, e.g. in the
state transition PREOP->SAFEOP or, as in Fig. CoE reset as a startup entry, in SAFEOP->OP.
All backup objects are reset to the delivery state.
