If the hardware catalog supplied with STEP 7 is too large or too difficult for you to
use, you can create your “own” catalog. In this way different catalog profiles are
produced. The basis for each new catalog profile is the modules/components
catalog with which you are already familiar. The profile of this catalog is known as
“standard;” you are free to assign names of your own choice to the catalog profiles
you create.

To create a new catalog profile, proceed as follows:

1. Select the menu command Options 

 Edit Catalog Profiles.

The application is opened with two catalog profiles: the “Standard” profile and
an “empty” profile containing no components.

2. Drag the required folders and modules from the standard profile window and

drop them in the “empty” profile window. You can also adapt the structure to
meet your requirements using the menu command Insert 

 New Folder.

3. Save the new catalog profile using the menu command File 

 Save As; choose

a suitable name for the new profile.

The name of the new profile then appears in the “Profile” list box in the
“Hardware Catalog” window and can be selected.

To prevent the “Hardware Catalog” window from obscuring the contents of the
station window, you can “dock” it on one side of the application window. Simply
double-click on the area above the “Profile” list box in the “Hardware Catalog”
window. To release the “docked” window, double-click on this area again.

You can change the size of the “Hardware Catalog” window when it is in the
“undocked” state.

If you select the function PLC 

 Download and follow the dialog boxes, you can

execute the following actions with a programming device:

Switch the CPU to STOP mode

(if the mode selector is set to RUN-P)

Compress memory

(if insufficient contiguous free memory is available)

Set the CPU to RUN
