Table 4-10 Example procedure for creating and loading PLC symbols
Step Description

"Rename" from the shortcut menu.
● You can change symbols of the individual elements in the block editor.

4 Importing PLC symbols in SINUMERIK Operate (Page 89)
4.10.2 Exporting PLC symbols
Note
Deleting unwanted blocks before exporting PLC symbols
If you have saved unwanted blocks in your project, this lengthens the time required for
exporting and importing PLC symbols.
Consequently, delete unwanted blocks that you copied previously from the basic program
library prior to the export.
