19.2 Compiling and Downloading Several Objects from the PG
Programming with STEP 7

Special considerations when compiling and downloading connections
If, in a module, you select the "Connections" object as the one to be compiled, then STEP 7
automatically selects the corresponding "Connections" object in the connection partner. By doing
this, STEP 7 always creates consistent configuration data (system data blocks). The automatically
selected objects cannot be directly deselected manually. However, the selection is automatically
removed if the originally selected "Connections" object is also deselected.
If, in a module, you select the "Connections" object as the one to be downloaded, then STEP 7
automatically selects the "Compile" check box. In addition, STEP 7 also selects the "Compile" and
"Download" check boxes for all connection partners. If only objects of the "Connections" type were
selected, you can also download the connections when the CPU is in RUN-P operating mode.
You can use NetPro to download individual connections.
Compiling and downloading hardware: effects on connections
If you select the "Hardware" object as the one to be compiled or downloaded, all "Connections"
objects below the hardware selected are also automatically selected to be compiled or
downloaded. In this case, however, the connection objects at the connections partners are not
automatically selected as well!
