PLC Address Space Configuration by .SDFI File
The symbolic names of the SIMATIC S7 data need to be provided via an .SDFI
file. You can generate the .SDFI file using the Softing dataFEED Exporter
tool. This tool uses the STEP 7 or TIA Portal project files as input and allows
to select one SIMATIC S7 device to generate the .SDFI file containing the
symbol definition.
Proceed as follows to convert and import symbol files:
- Download dataFEED Exporter
to that PC where the PLC configuration software (STEP 7 or TIA Portal)
is installed
- Execute the installation file and follow the instructions of the
installation wizard
- Run dataFEED Exporter
- Follow the dataFEED Exporter instructions to load and convert your
STEP 7 or TIA Portal symbol files
- Save the converted .SDFI file to your PC
- Upload the .SDFI file to the
Siemens SINUMERIK 840D connection configuration.
