After new installation / update of the SIMOTION P Kernel
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.
Note
Restart of SIMOTION P320-4 required
After a new installation or update of the SIMOTION P Kernel, a restart of the SIMOTION P320-4
is generally required.
If the device is not restarted, the new SIMOTION P Kernel is not activated and you continue
to work with the old firmware.
