Dear Friends,

Am using a s7-400 hot redundancy system.
in the Power supply we are having two batteries.
can you pls tell me if the program inside the RAM will be lost if i switch off the power supply module.

regards

IF
power is switched on OR the batteries are good​
THEN
the program in RAM will remain​
ELSE
the program in RAM will be gone​
ENDIF

Or you can look at it the other way around:

IF
power is switched off AND the batteries are bad​
THEN
the program in RAM will be gone​
ELSE
the program in RAM will remain​
ENDIF

Kind regards,
