Procedure
To assign IO devices to an IO controller, proceed as follows:
1. Place the pointer of the mouse over the interface of the IO device.
2. Press and hold down the left mouse button.
3. Move the pointer.
The pointer now uses the networking symbol to indicate "Networking" mode. At the same
time, you see the lock symbol on the pointer. The lock symbol disappears only when the
pointer is over a valid target position.
4. Now move the pointer onto the interface of the IO controller. You can keep the left mouse
button pressed or release it when performing this action.
5. Now release the left mouse button or press it again (depending on your previous action).

Result
You have assigned an IO device to an IO controller.
Checking the assignment
You can find an overview of the communication relationships in the "IO communication" tab
in the tabular area of the network view. This table is context-sensitive for selection in the
graphic area:
● Selection of the interface shows the I/O communication of the respective interface.
● Selection of the CPU shows all I/O communication of the CPU (including PROFIBUS).
● Selection of the station (as in the above figure) interface shows the I/O communication of
the complete station.
