Mitsibishi q series

I have a mitsubishi q series plc. I have logic programed that counts parts cycle times etc. If power is cycled to the cell all data is lost. Is there a way I can prevent this from happening, can it store the values and reload them upon power restore?

Thanks

hi.
Which series PLC do you use?
You can setting in parameter. In task "device" you can setting range by latch start to latch end per each device you want to store.
