Store Parameters
Store Parameters controls when and if the changes made to a parameter (by SDO Write) are backed
up (stored) into EEPROM. An SDO read of Save All Parameters sub-index 01h will return the present
EEPROM Store Parameters functionality (see Read data column). An SDO write to sub-index 01h
will change the EEPROM Store Parameters functionality (see Write Data column).
Note that when you write to Store Parameters, the data value is always saved in EEPROM (even
NO_SAVE). is allows the eXm to power up in the desired mode.
Store
Parameters Function
Write Data Read Data Description
NO_SAVE 0 0
Device will not save parameter changes to EEPROM.
SAVE_ON_COMMAND 1 1
Device will save changes to EEPROM on command.
AUTO_SAVE 2 2
Device will save each change to EEPROM automatically.
BOTH_SAVE 3 3 Device will save each change to EEPROM automatically
and all parameters on a “save” command.
SAVE_COMMAND “save”
65766173h
N/A Text string that commands all parameters to be saved
from working RAM to Normal runtime EEPROM.
BACKUP_COMMAND “bkup”
70756B62h
N/A Text string that commands all parameters to be
saved from working RAM to the Backup EEPROM.
For increased security, a text string is required for SAVE_COMMAND and BACKUP_COMMAND.
At rst glance, the ASCII looks “backward.” is is because CANopen denes that the LSB goes rst
and MSB is sent last. erefore “save” (which is data bytes 5, 6, 7 and 8) is written as “evas” when
converting it to hex (data bytes in proper descending order). e ASCII hex values for each character
are 65h (“e”), 76h (“v”), 61h (“a”), and 73h (“s”), which results in hex 65766173h.
e “save” string will cause the eXm to write all RW parameters from the working RAM locations
into the normal runtime EEPROM locations. e Normal EEPROM block is accessed during
SDO write requests. e “bkup” string will write into the secondary Backup EEPROM block. is
block can not be written to by normal SDO write requests and can only be written to in bulk by
the “bkup” command.
