19.2 Compiling and Downloading Several Objects from the PG
19.2.1 Requirements for and Notes on Downloading
Downloading Block Folders
For block folders, only logic blocks can be downloaded. Other objects in the block folder, such as
system data (SDBs), etc. cannot be downloaded here. SDBs are downloaded through the
"Hardware" object.
Note
For PCS 7 projects, blocks cannot be downloaded using the dialog "Compile and Download Objects"- just as they
cannot be downloaded from the SIMATIC Manager. For PCS 7 projects, the following applies: PLCs must only be
downloaded to by means of CFCs in order to ensure correct sequencing during the download. This must be done
to prevent the CPU from going into STOP mode.
To determine whether the given project is a PCS 7 project, check the project properties.
Downloading the F-Shares of Failsafe Controllers
For security reasons, a password must be entered before modified F-shares can be downloaded.
For this reason, with the "Compile and Download Objects" function, the download procedure will be
aborted with an error message. In this case, load the appropriate parts of the program along with
the optional package to the PLC.
Downloading the Hardware Configuration
Downloading the hardware configuration (i.e. downloading the offline SDBs) by means of the
"Compile and Download Objects" function will only run without interruption for all selected objects if
no error messages or prompts are triggered. The following section provides information on how to
avoid such messages or prompts.
