19.3 Uploading from the Programmable Controller to the PG/PC
Programming with STEP 7
Manual, 05/2010, A5E02789666-01 435
Two Distinct Cases
When uploading blocks from the CPU to the programming device, remember that there are two
distinct situations:
1. The user program to which the blocks belong is located on the programming device.
2. The user program to which the blocks belong is not on the programming device.
This means that the program sections listed below, that cannot be downloaded to the CPU, are not
available. These components are:
• The symbol table with the symbolic names of the addresses and the comments
• Network comments of a Ladder Logic or Function Block Diagram program
• Line comments of a Statement List program
• User-defined data types
19.3.3.1 Editing Uploaded Blocks if the User Program is on the PG/PC
To edit blocks from the CPU, proceed as follows:
1. Open the online window of the project in the SIMATIC Manager.
2. Select a "Blocks" folder in the online window. The list of loaded blocks is displayed.
3. Now select the blocks, open and edit them.
4. Select the menu command File > Save to save the change offline on the programming device.
5. Select the menu command PLC > Download to download the changed blocks to the
programmable controller.
19.3.3.2 Editing Uploaded Blocks if the User Program is Not on the PG/PC
To edit blocks from the CPU, proceed as follows:
1. In the SIMATIC Manager, click the "Accessible Nodes" toolbar button or select the menu
command PLC > Display Accessible Nodes.
2. Select the node ("MPI=..." object) from the list displayed and open the "Blocks" folder to display
the blocks.
3. You can now open blocks and edit, monitor, or copy them as required.
4. Select the menu command File > Save As and enter the path for the programming device
where you want to store the blocks in the dialog box.
5. Select the menu command PLC > Download to download the changed blocks to the
programmable controller.
