Type Update With Interface Change In Run - Siemens SIMATIC CPU 410 System Manual

Without a backup battery, the following data is not buffered:
● Diagnostic buffer
● Security event buffer
● Date and time
● Process image
● Data blocks that were not backed up to the load memory with CFC
● Data blocks created by the program (CREATE_DB instruction)
● Operating hours counter
● Bit memory
● Timers
● Counters
Caution when replacing a CPU
If you reuse a CPU that has previously been used at a different location, ensure that the
contents backed up in the load memory cannot pose a hazard at the new point of use.
Reset the CPU to factory settings if its previous use is unknown.
Buffering with a battery
If you are using one or two backup batteries in the power supply module and the power
supply module is switched off or the supply voltage in the CPU and configurable modules
fails, the set parameters and the memory content (RAM) will be buffered via the backplane
bus as long as there is still battery capacity.
