7. Configure the transfer areas. The transfer areas are found in the area navigation section
"I-device communication".
– Click in the first field of the "Transfer area" column. STEP 7 assigns a default name
which you can change.
– Select the type of communication relation: you can currently only select CD or F-CD
for "Controller-device communication relation".
– Addresses are automatically preset; you can correct addresses if necessary, and
determine the length of the transfer area which is to be consistently transferred.

8. A separate entry is created in the area navigation for each transfer area. If you select one
of these entries, you can adjust the details of the transfer area, or correct them and
comment on them.
Configuring an I-device with a GSD file
If you use an I-device in another project, or if the I-device is used in another engineering
system, then configure the higher-level IO controller and the I-device as described above.
However, click on the "Export" button after configuring the transfer areas so a new GSD file
is created from the I-device. This GSD file represents the configured I-device in other
projects.
The "Export" button is found in the "I-device communication" section of the Inspector
window.
The hardware configuration is compiled and the export dialog opened.
Assign a name for the I-device proxy as well as a description in the fields provided. Click the
"Export" button to complete your process.
Finally, import the GSD file, for example, in another project.
