All data or files on the PLCE partition are automatically encrypted and are
therefore protected from unauthorized access. The only exception is the
active machine parameter file. If the active MP file is stored in the PLCE
partition, it can nevertheless be edited when you switch to the Machine
Parameter Programming mode of operation.
The control operator does not need to know the password to back up or
restore the PLCE data. The encrypted content remains protected. When
restoring a backup on a control, you must make sure that the password on the
control (in the SIK or OEM.SYS) is identical to the password that was used for
creating the PLCE.BIN file or the PLCE partition.
To enable automatic updating of the PLCE partition through a restore process
or software update, you must manually separate the PLCE partition before the
restore process by using Unmount.
You must keep the following in mind to ensure that the PLCE partition is
successfully overwritten with the PLC:\PLCE.BIN file during a restore process
or a software update:
The password for the PLCE partition is stored in the SIK or OEM.SYS in the

control.
The password in the control matches the password in PLCE.BIN.

The PLCE partition has been separated (Unmount).

The PLCE partition offers sufficient storage space for the new data.

A software update can contain either the PLC:\PLCE.BIN file or the
PLC:\_mpupdate\plce.zip file.
If the software update contains a PLC:\PLCE.BIN file, the requirements
described above under "Backup/Restore and PLCE" apply as well.
If the software update contains a PLC:\_mpupdate\plce.zip file, the following
requirements apply:
The .zip file must be encrypted with the same password as the PLCE: drive.
When the control is started up the next time, this file is unpacked and the
corresponding files are copied to PLCE:. This .zip file can be created using
PLCdesignNT with version 2.5 or later.
Danger
Please note that the encryption algorithm of this .zip file is less secure than
encrypting the PLCE partition on the hard disk of the control.
