If a compatible SIMOTION P Kernel is installed on an already commissioned
SIMOTION P320‑4, the user data backed up in the SRAM is retained.
However, the current software version of the SIMOTION PP320-4 must be identical to the
software version with which the backed-up user data of the SRAM was created.
Now SIMOTION P320-4 is immediately ready to run again.
Note
If you do not want the backed up user data to be used again, you will have to recommission
the SIMOTION P320-4.
