Setting up a connection

Automatic connection
STEP 7 sets up a connection automatically (for example PG or HMI connection) if you have
connected the PG/PC interface to an interface of the CPU physically and have made the
interface assignment in STEP 7 in the "Go online" dialog.
Setting up a programmed connection
You set up the programmed connection in the program editor of STEP 7 in the context of a
CPU by assigning instructions for communication, for example TSEND_C.
When specifying the connection parameters (in the Inspector window, in the properties of the
instruction), you are supported by the easy-to-use user interface.
