6.2 Configuring the CPU
Upload blocks from the CPU to a project
You use this option to load blocks from the CPU back to the offline project.
The following requirements must be met before you start to backup the blocks:
● The project associated with the user program is open.
● The CPU has been set up in the project.
● The CPU is connected to the programming device/PC via the PROFINET interface.
Interfaces of CMs/CPs are also supported.
● The CPU is online.
● The blocks that are to be loaded must be compatible with STEP 7.
● The CPU is in STOP or RUN mode.
To upload all blocks from the CPU to a project, select the "Program blocks" folder in the
project tree. In the "Online" menu, select the "Upload from device (software)" command.
To upload an individual block, select the required block in the "Program blocks" folder. In the
"Online" menu, select the "Upload from device (software)" command.
When a block is uploaded, the start values from the load memory of the CPU is transferred
as start value in the offline version of the project.
A block is only uploaded from the CPU to a project if the online version of the block differs
from the offline version of the block in the project.
After you have completed the backup of blocks from the CPU, you can perform the required
changes offline and transfer the block to the CPU again. To do so, proceed as described in
the following section.
