S7 Symbol Import

The symbol import is needed for the S7 200 / 300 / 400 / 1200 only.

The S7 1500 uses the symbols directly. No symbol import is necessary.

Projects from Step7 and from TIA Portal can be imported.

The import of S7-1500 is not necessary because the symbols are present in the PLC and are read out online.

In the dialog box, you can import a symbol from an existing PLC program.
