What is the name of the program? When the PLC loses its memory it reverts to the default name of "HHP".

some body lift the CPU wile it was turn on will be erased the program

If someone removed the CPU module from the base plate for more than a few minutes that would cause the RAM memory to be lost because the battery backup for the RAM memory is located on the power supply module.

there is other way to recover the program . unfortunately no Backup program

For that CPU model (CPU331) without an EEPROM, once the program is gone from RAM there is no way to recover it.

Thank you Steve Now it is clear we need to Redo the Code
