Click Plus C2-03CPU Retentive Data Memory Registers is SRAM or NVM
Click Plus C2-03CPU
I'm wondering if Retentive Data Memory Registers is stored in SRAM that is battery/capacitor powered or is it a type EEPROM and will be stored indefinity?
Thanks,

Hi @ambermoon59 (Customer)
With power off, the Click PLUS PLC will store the SRAM data for 1 hour using the supercapacitor. Once the supercapacitor is discharged, all data in the SRAM is cleared.
To prevent the loss of SRAM memory during power down, the Click PLCs have a battery backup feature that will retain data in the SRAM for three years.
D0-MC-BAT (CR2032) is the battery for the Click PLUS PLC.
