Profinet to Modbus TCP Gateway


I am looking for gateway between Siemens 315 CPU over profinet and modbus TCP slave. In dropdown menu to select anybus x gateway network interface 1. I see profinet IO device/slave and profinet Irt device/slave, but I am not sure what is the difference between two. Any help on answering this question is much appreciated.

IRT stands for Isochronous Real-Time Communication, see:

If you don’t need it, you can just get the Profinet I/O version.
