EL6731
Meaning
Information for identifying the slave
Vendor ID of the EtherCAT slave
Product code of the EtherCAT slave
Revision number of the EtherCAT slave; the low word (bit
0-15) indicates the special terminal number, the high
word (bit 16-31) refers to the device description
Serial number of the EtherCAT slave; the low byte (bit
0-7) of the low word contains the year of production, the
high byte (bit 8-15) of the low word contains the week of
production, the high word (bit 16-31) is 0
Meaning
Information for standardized loading and saving of
backup entries
Checksum of the Backup Parameter Storage (object
0x10F2 [} 143], word 2-3)
Meaning
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:
Word-Offset Description
0 Command: with 0xC0DE, the received data
are stored in the flash memory
1 Length of the data from word offset 4 in
bytes
2-3 Checksum, which is calculated locally
4 Index of the object of the 1
5 len1: Length of the object of the 1
SDO as CompleteAccess (from SubIndex
0) in bytes
6-n1 Data of the object of the 1
CompleteAccess (n1 = 2*((len1+1)/2)+5)
n1+1 Index of the object of the 2
n1+2 len2: Length of the object of the 2
SDO as CompleteAccess (from SubIndex
0) in bytes
(n1+3)-n2 Data of the object of the 2
as CompleteAccess (n2 =
2*((len2+1)/2)+n1+2)
...
m Index of the object of the 3
m+1 len3: Length of the object of the 3
SDO as CompleteAccess (from SubIndex
0) in bytes
(m+2)-n3 Data of the object of the 3
as CompleteAccess (n3 = 2*((len3+1)/2)+m
