PROFINET™ is the open industrial Ethernet standard of PROFIBUS & PROFINET International (PI) for automation. PROFINET™ uses TCP/IP and IT standards, and is, in effect, real-time Ethernet, as such the port must be configured with IP address. Two parameters that need to be configured on device are CPU Slot & Station Name .

PROFINET™ uses string in Path column instead of numerical value in Address column for tag data address. Fill in the Path entry with the device actual tag I/O addressing format. The path string must match with the tag name at Siemens S7-1200 Tags, in TIA Portal for instance.

As we can see from example screenshot above, the tag data type must be matched with the PLC according to the following table.
