Create Blocks From External Sources - Siemens SINUMERIK 840D sl Configuration Manual

Programming the PLC

3.9 Create blocks from external sources

For example, this function is useful in the following situations:
● Creation of a dedicated group for the blocks of the basic program and of the user
program.
This allows you to display individually the editable blocks of the user program.
● Organize specific related program blocks (e.g. axis DBs).
● Organize specific program blocks in a group in order to save them quickly and easily in a
reload archive (Page 41).
To maximize the overview window, select the "program blocks" folder and click the
"Maximize/minimize the view" icon in the project navigation toolbar.
Information about the overview window can be found in the information system of the TIA
Portal, keyword "overview window".
3.9 Create blocks from external sources
You do not manage external source files (e.g. *.STL or *.SCL) in TIA Portal in the "Program
blocks" folder, but in the "External sources" folder, e.g. under "CNC_1 > PLC_1 > External
sources". You can then generate blocks from the sources maintained there. These are saved
in the "Program blocks" folder.
You do not edit the files in the "External sources" folder using a TIA Portal editor, but with
any external editor, which you define under Windows.
Requirement
An external source is available in STL or SCL format.
Procedure
1. In the project tree, select the "Add new external file" command in the "CNC_1 > PLC_1 >
External sources" folder.
2. Select the external file (*.STL or *.SCL) that you want to add in the "Open" dialog.
The external file is copied to the "External sources" folder in the project tree.
Note
Displaying external sources (e.g. STL files) using an external editor
The internal editor of the TIA Portal does not display external sources.
If you add and open an external source in the TIA Portal, the file will be opened with the
application linked with the associated file type (e.g. STL) in Windows (e.g. Microsoft
Editor).
