Introduction
This entry shows you how to configure an S7-1200, a PC station and an S7
connection in the TIA Portal so that you can exchange data between the stations
over Industrial Ethernet.
Note
In the TIA Portal you need STEP 7 Professional, because with STEP 7 Basic you
cannot configure a PC station, but only the SIMATIC S7-1200.
