Downloading and Uploading
19.3 Uploading from the Programmable Controller to the PG/PC
Programming with STEP 7
Manual, 05/2010, A5E02789666-01 433
19.3.1 Uploading a Station
Using the menu command PLC > Upload Station you can upload the current configuration and all
blocks from the programmable controller of your choice to the programming device.
To do this, STEP 7 creates a new station in the current project under which the configuration will be
saved. You can change the preset name of the new station (for example, "SIMATIC
300-Station(1)"). The inserted station is displayed both in the online view and in the offline view.
The menu command can be selected when a project is open. Selecting an object in the project
window or the view (online or offline) has no effect on the menu command.
You can use this function to make configuring easier.
• For S7-300 programmable controllers, the configuration for the actual hardware configuration is
uploaded including the expansion racks, but without the distributed I/O (DP).
• For S7-400 programmable controllers, the rack configuration is uploaded without the expansion
racks and without the distributed I/O.
With S7-300 systems without distributed I/O, all you have to do is specify the modules in more
detail (order number) and assign them parameters.
Restrictions when Uploading Stations
The following restrictions apply to the data uploaded to the programming device:
• Blocks do not contain any symbolic names for parameters, variables, and labels
• Block do not contain any comments
• The entire program is uploaded with all the system data, whereby not all the data can be
processed further
• The data for global data communication (GD), configuring symbol-related messages, and
configuring networks cannot be processed further
• Force jobs cannot be uploaded to the programming device and then loaded back to the
programmable controller.
