PROFINET 智能设备功能的组态与应用：

With the I-Device function, various tasks can be realized. These functions are explained in the configuration and application examples.

Mainly in mechanical engineering, it is often necessary to realize a simple deterministic communication between modules or machines without the need to fall back on "additional" connection-oriented communication paths.

The following requirements have to be considered here:

• Efficient engineering, even for fail-safe applications
• Sustained reduction of engineering costs and commissioning time
• Reduction of the required network and system components
• Simplification of communication within machines and plants
• Simple communication between heterogeneous systems

Solution
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.

Advantages
The I-device function has the following advantages:

• Leaner and more flexible topology
• Simple interconnection of controllers from several projects
• Integration of Siemens controllers with controllers of other manufacturers in a network (via GSD files)
• Saving PN/PN couplers
• Integrated communication with all devices in the network without additional router mechanism
