storage
If this object is used, no StartUp SDOs may be transmit-
ted in the PREOP state, since the Backup Parameter
Storage contains the complete StartUp SDOs (see Con-
figuration of the EL6731 with Backup Parameter Storage
[}136]). The EL6731 is rebooted 5s after the flashing of
the Backup Parameter Storage (switches to INIT with AL
status code = 0x60). The data have the following mean-
ing:
