13.2.5 Rules for Setting Block Properties in STL Source Files
You can more easily identify the blocks you created if you use block properties and you can also
protect these blocks from unauthorized changes.
The block properties can be checked or changed in incremental input mode using the menu
command File > Properties under the "General - Part 1" and "General - Part 2" tabs.
The other block properties can only be entered in the source file.
The following applies in source files:
• Block properties precede the variable declaration section.
• Each block property has a line of its own.
• The line ends with a semicolon.
• The block properties are specified using keywords.
• If you enter block properties, they must appear in the sequence shown in the Table of Block
Properties.
• The block properties valid for each block type are listed in the Assignment: Block Property to
Block Type.
Note
The block properties are also displayed in the SIMATIC Manager in the object properties for a block.
The properties AUTHOR, FAMILY, NAME, and VERSION can also be edited there.
