19.2.2 Compiling and Downloading Objects
In the "Compile and download objects" dialog you prepare the objects that can be selected in your
project or multiproject for transfer to the PLC and their subsequent download (if desired). This
dialog can be used for objects in a station, a project or a multiproject.
Depending on the object selected, certain information may not be displayed. In addition, not all the
functions described below may be available for these objects. In particular, these restrictions may
apply to objects that were created with optional software packages.
For blocks in a block folder "compile" means that the consistency of the blocks is checked. In the
following, for simplicity, the consistency check for blocks will be referred to as compilation.
Procedure:
1. In SIMATIC Manager, select the object that you want to compile, or compile and download.
The following objects can be selected in the SIMATIC Manager:
- Multiproject
- Project
- Station
- S7 program without station assignment
2. In the SIMATIC Manager, select menu command PLC > Compile And Download Objects.
3. Select "Only compile" if you want to perform a check of the blocks without downloading them to
the PLC. Select this option if you do not want to download any of these objects to the PLC.
Note: Stations with missing HSPs are not compiled and loaded (the check boxes are not
visisble).
4. To prevent incomplete downloads to stations due to compilation errors, select the check box
"No download on compilation error". If this check box is selected, nothing will be downloaded. If
the check box is not selected, then all objects compiled without error are downloaded. Objects
that caused an error during compilation are not downloaded.
5. If you want to compile and download connections, select the corresponding check box for the
"Connections" object.
A multiproject is particularly suited for use as a starting point, since all connection partners for
cross-project connections can also be downloaded from this object.
6. In the "Compile" and "Download" columns, select the objects that you want to compile or
download. You selections will be indicated by checkmarks. If you selected "Compile only" in
Step 3, the "Download" column will be grayed out and unavailable.
7. Click on "Start" to begin the compilation.
8. Follow the instructions on the screen.
After the compilation or download is complete, a full log is displayed. You can open the full log or
single-object log at any time:
• Click on the "All" button to view the full log of the complete action.
• Click on "Single object" button to view only the log of the object you have selected in the object
table.
