Probably lost the program, but also watch out for faulty PSU AND lost program.  If it was a black tab on memory module that would be a eeprom module but as it is a red one it will drop it's program.

Morning,

You have lost the program for sure. There's a battery inside the RAM cartridge  memory and if it has never been replaced the program vanish each time you power off the plc.
