Detailed Description of the Module Buffer Memory Details: CANopen Mode
3 – 16 MITSUBISHI ELECTRIC
3.5.3 Save/Restore Configuration (Un\G22)
This buffer memory specifies two bits that allow to restore the factory default configuration in the buf-
fer memory and to store the buffer memory configuration into the Flash ROM. To execute the request,
please set Y(n+1)F to ON (refer to section 3.3.2).
Both bits will be reset automatically if the restore or save procedure is completed, and X(n+1)F will
turn ON.
3.5.4 Baud Rate (Un\G24)
In Un\G24 the baud rate is set. The current baud rate can be found in Un\G37.
Bit Description
0 Bit = 1: Save configuration to Flash ROM
1
Bit = 1: Restore factory default configuration (not saved to Flash ROM)
2–15 Reserved
Tab. 3-9: Assignment of the bits in buffer memory address Un\G22
NOTES
If both bit 0 and bit 1 are set simultaneously the buffer memory and Flash ROM will be reset to the
factory defaults.
If only bit 1 is set, factory default values are written to the configuration buffer memory but not
stored in the Flash ROM. In order to store changes made to the configuration buffer memory, set
Un\G22 bit 0 after changing the configuration.

NOTES The baud rate must be equal for all nodes in the network.
The new value needs to be stored by Un\G22. Then Y(n+1)F has to be turned ON and the module
has to be restarted to make the new setting effective.
At low baud rates a too fast data exchange and/or high bus load can result in a transmission data
queue overflow error (bit 8 in Un\G29, refer to section 3.5.7).
