QUESTION:
How long is data memorized in SIMOCODE-DP 3UF5 after a power failure?
Data were apparently lost during a power failure.


ANSWER:
SIMOCODE-DP 3UF5 parameter data is retained in an EEPROM and safe against loss for an unlimited amount of time.

The following however can happen:
If the parameterization of ''Block DP Parameter'' has been forgotten, at CPU restart the set of parameters of the master gets transferred to SIMOCODE. If no parameters were created there however all data in SIMOCODE get overwritten with ''0''. It appears as if all data was lost during the power failure.
