Special power-up situations

10.4.1

Special startup situations overview

The special power-up situations are described in the following:
● Non-volatile data and SRAM handling (Page 123)
● After new installation / update of the SIMOTION P Kernel (Page 125)
● After importing a backup copy (Page 125)
● After a power failure/POWER FAIL (Page 125)
Requirements
You are familiar with the user storage concept of the non-volatile data on the
SIMOTION P320‑4.
10.4.2

Non-volatile data and SRAM handling

Non-volatile data, also called retain data, is retained when SIMOTION P320‑4 suffers a power
failure. The data is buffered with the battery in the static memory area (SRAM) on the
SIMOTION P320‑4.
SRAM handling
If the serial number of the SIMOTION P320‑4 is known:
The serial number of the SIMOTION P320‑4 corresponds to the one that was last saved on
the SIMOTION P320‑4.
SRAM image (storage medium) or SRAM backup (storage medium) is OK, if:
● The SIMOTION software release of the SRAM image/backup matches the installed
software release.
● Windows has been shut down properly (the POWER FAIL mechanism of SIMOTION P
does not suffice here).
● The checksum test on the SRAM image/backup was successful.
● The battery status was good when the SRAM image was backed up.
