No.
Designate the EEPROM function in the EEPROM function designation area (
When registering the current buffer memory values as the default values, designate "0". To
1)
return the values to the default values, designate "4".
When writing with the buffer memory automatic update function, refer to section 5.6.
When writing with the transmission/reception buffer, refer to section 5.7.4.
2) The EEPROM function request signal (RYn7) turns ON.
After the EEPROM function execution is completed, the EEPROM function normal/error complete

shown below.
Name
Designate the EEPROM function.
When using the buffer memory setting value registration function,
designate whether to register or initialize the buffer memory setting
values.
0 : Buffer memory setting value registration
4 : Buffer memory setting value initialization
The status of the buffer memory when the R2 is started up is stored.
0 : R2 default values (default value)
1 : Default values registered in EEPROM
