you can restore the plant to an earlier state. Before you download a changed configuration to the CPU, first use the option "Backup from online device" to create a complete backup of the current device state. |
| You may make changes in the operation of your plant. For example, you may add new devices, |

Snapshot of the actual values
To allow you to restore the actual values at a later date, back up the actual values of the
data blocks using the option "Snapshot of the actual values".The following example shows how to carry out a complete backup of the current device state
of the CPUs in STEP 7. The R/H redundant system is in the RUN-Solo system
state.
1. Right-click to select the R/H system in the project tree.
2. Select the "Backup from online device" command from the shortcut menu.
The "Upload preview" dialog window sets out the key information on the backup process to
be run:The preview shows that the backup target is H-System_1.
For a backup, the redundant system R/H must be in the STOP system state.
In the "Action" column, select the "Stop module" command from the drop-down menu.Different categories of texts are created when you configure a CPU, for example
● Object names (names of blocks, modules, tags, etc.)
● Comments (for blocks, networks, watch tables, etc.)
● Messages and diagnostic texts
Texts are provided by the system, for example texts in the diagnostics buffer, or they are
created during configuration, for example, messages.
Texts exist in the project in one language or, after a translation process, in multiple
languages. You can maintain project texts in all languages available to you in the project tree
(Languages & resources > Project texts). The texts created during configuration can be
downloaded to the CPU.
The following texts containing the project data are downloaded to the CPU in the chosen
languages and are also used by the CPU display:
● Diagnostics buffer texts (not editable)
● Status texts for the module status (cannot be changed)
● Message texts with associated text lists
● Tag comments and step comments for PLC Code Viewer
● Comments in watch tables
The following texts containing the project languages are also downloaded to the CPU in the
chosen languages, but are not used by the CPU display:
● Comments in tag tables (for tags and constants)
● Comments in global data blocks
● Comments of elements in block interfaces of FBs, FCs, DBs and UDTs
● Network titles in blocks written in LAD, FBD or STL
● Block comments
● Network comments
● Comments of LAD and FBD elements
The R/H CPUs support archiving of multilingual project texts in up to three different
project languages. If the project texts for a project language nevertheless exceed the
memory space reserved for them on the SIMATIC memory card, the project cannot be
downloaded to the CPU. The download is aborted with a notice that not enough memory
space is available. In such a case, take measures to reduce the required storage space, for
example by shortening comments.
