S7 connection partners of the current project as well as the option
"unspecified". An unspecified partner represents a communication partner
which is not currently in the STEP 7 project (for example, a third party device
communication partner).

Checkbox to select Local CPU as the active connection
One-way Checkbox to specify a one-way or two-way connection; read-only
Note: In a PROFINET GET/PUT connection, both the local and partner
devices can act as a server or a client. This allows a two-way connection, and
the "One-way" checkbox is unchecked.
In a PROFIBUS GET/PUT connection, in some cases, the Partner device can
only act as a server (for example, an S7-300), and the "One-way" checkbox is
checked.
