Restrictions when Uploading from the Programmable Controller
The following restrictions apply to the data uploaded from the programmable controller to the
programming device:
• Blocks do not contain any symbolic names for parameters, variables, and labels
• Blocks do not contain any comments
• The entire program is uploaded with all the system data, whereby the system can only continue
to process the system data belonging to the "Configuring Hardware" application
• The data for global data communication (GD) and configuring symbol-related messages cannot
be processed further
• Force jobs are not uploaded to the programming device with the other data. They must be
saved separately as a variable table (VAT)
• Comments in the module dialog boxes are not uploaded
• The names of the modules are only displayed if this option has been selected during
configuration (HW Config: the option "Save object names in the programmable logic controller"
in the dialog box under Options > Customize).
