Commissioning (software)
10.8 Data storage concept
Storage medium image
With a storage medium image, the entire storage medium can be backed up and restored.
This allows series commissioning to be performed (requirement: identical hardware!).
A storage medium image must be created both for the internal storage medium (Drive C) and
for the external CFast card (Drive D). When creating the image with the SIMATIC IPC Image
Creator, an image can be created jointly for one internal and one external storage medium.
When loading an image, be aware that the images for the internal and external storage media
must be loaded separately and that the wizard must therefore be run twice. It is not possible
to load the image onto both drives in a single process.
The restore DVD contains a storage medium image of the plant with which the delivery state
of the SIMOTION P320-4 can be restored.
Various mechanisms are available for backing up and restoring data for the SIMOTION
P320-4.
These mechanisms are described in the following sections, starting with the largest possible
scope of a backup to the backing up of variables.
Although the backup/restore of data in many cases is initiated by the user, it is sometimes also
performed automatically or started by the user program.
In addition to restoring defined states and updating/reloading a project in the target device,
data backups are also needed to prevent data loss resulting from a hardware defect or failure
of the backup battery.
Project update
The Project update (Page 160) section describes options for updating/retransferring or backing
up a SIMOTION project.
Application
● Transfer of a project to the newly installed SIMOTION P320-4
● Series commissioning
Advantage
Series commissioning is also possible without a programming device or using remote
maintenance.
Disadvantages
The SIMOTION version on the target device must exactly match the version of the device on
which the backup was created.
Single backups
The Single backups (Page 165) section describes the options for backing up and restoring
retain variables, retain TOs, unit variables, and global device variables.
