CANOpen Save PDO Settings to EEPROM

I am using the SBLM1360T and able to map the TPDO/RPDOs but cannot save to EEPROM. Meaning they have to be reset on a power cycle. 

I am sending the following commands after setting the TPDO/RPDO

ID BYTE0 -> BYTE&
0x00 0x80 0x01 #Using node 1 setting the node to pre-operational.
0x601 0x23 0x10 0x10 0x01 0x65 0x75 0x61 0x73 #Try and save all (also tried subindex 02 and 03 to just save the communication profile.

Repose on 0x581 shows invalid request. 

Thanks.
