Configuration and Application of the PROFINET I-Device Function
https://support.industry.siemens.com/cs/document/109478798/

An I-device is a CPU/CP, which is used as an intelligent IO device. With this function, PROFINET enables communication with lower-level devices as well as IO communication with other higher-level or central controllers as IO device.

I-device enables very easy and fast communication between two PROFINET IO controllers.
I-device enables accessing the IO address via the PROFINET IO protocol without using PN/PN couplers.
These configuration instructions show the application in a standard environment. The following scenarios are described:
S7-CPU as I-device
SIMATIC-NET CP as I-device
SIMOTION as I-device

Safety-related IO controller-I-device communication
These configuration instructions show the application in a fail-safe environment. The following scenarios are described here:
F-CPU as I-device within a project
F-CPU as I-device in two separate projects
Data record communication via I-device
The application example shows the data set communication using an I-device.
