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.

Configured I/O in TIA Portal

Configuring PROFINET tags in IntegraXor

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

Note

Turn Input tag attribute to True for Read-Only input tag.
