10F2:0 Backup parameter
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 EL6731-0010 with Backup Parameter
Storage). The EL6731-0010 is rebooted 5s after the
flashing of the Backup Parameter Storage (switches to
INIT with AL status code = 0x60). The data have the fol-
lowing meaning:

Index 1600 DPS RxPDO-Map Slave
Index (hex) Name Meaning Data type Flags Default
1600:0 DPS RxPDO-Map
Slave
This RxPDO contains the DP input data of the DP slave,
which are sent to the DP master. There is an entry in the
RxPDO mapping object 0x1600 for each DP module with
DP input data configured in object 0x8002 [}170]. If the
DP slave does not contain any DP input data, then the
PDO mapping object 0x1600 does not exist. This PDO is
mandatory and must always be contained in the PDO As-
sign object 0x1C12 [}167] . SubIndex 0 contains the
number of DP modules with DP input data of the DP
slave.
