Online path: Establishing a connection to the CP

Requirements
First, establish a physical connection between the PG and the SIMATIC S7 station. You can
make this connection via one of the following:
● MPI
● PROFIBUS
● Industrial Ethernet (ISO protocol)
● Industrial Ethernet TCP/IP (IP protocol)
Establishing a connection to the CP
If you call special diagnostics for a specific module within a project, STEP 7 attempts to
establish a connection to the CP directly based on the project data. The path is set
automatically according to the current attachment in STEP 7.
If the connection cannot be established due to missing parameters, set the interface and
address parameters for access to the CP according to the descriptions below.
