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).

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.

Alternative restore value In some older terminals (FW creation approx. before 2007) the backup objects can be switched with an alternative restore value: Decimal value: 1819238756, Hexadecimal value: 0x6C6F6164. An incorrect entry for the restore value has no effect.
