Representation of PROFINET Interfaces in the Topology Overview in STEP 7
You can find the PROFINET interface in the topology overview in STEP 7. The PROFINET
interface for an IO controller and an IO device is represented as follows in STEP 7:
PROFINET interface of an IO controller in STEP 7
PROFINET interface of an IO device in STEP 7
These lines represent the PROFINET interface.
These lines represent the "ports" of a PROFINET interface.
