1 Task and Solution
Advantages
The solution presented here offers you the following advantages:

Lower costs through the reduction of additional IO devices and modules.

Real time capture in several CPUs.

Lower space requirements through the reduction of additional IO devices and
modules.

Lower communications burden through the suspension of CPU-CPU
communication.

No additional programming work for CPU-CPU communication.
Prerequisite
The following prerequisites must be met in order to use the "Shared Device"
function:

STEP 7 V12 SP 1 or higher

CPU as of FW 1.1 or higher as IO controller

IO device supports the "Shared Device" function
IO controllers that use the "Shared Device" function, are created in different
Note
projects.
In every project, you must ensure that the "Shared Device" is configured the
same at every station.
Characteristics with I-Device
If you use "I-Device" and the "Shared Device" function in parallel, please bear the
following conditions in mind:

A S7-1500-CPU configured as I-Device supports the "Shared Device" function
from firmware V1.5 or higher. The I-Device needs to be integrated into the IO
controller's IO system via a GSD import.

A S7-300-CPU or a S7-400-CPU configured as I-Device supports the "Shared
Device" function. You need to export the PROFINET-GSD file for the I-Device
from STEP 7 (from V5.5 or higher) and then import it in STEP 7 (TIA Portal).

A ET 200SP-CPU configured as I-Device supports the "Shared Device"
function from firmware V1.6 or higher. The I-Device needs to be integrated into
the IO controller's IO system via a GSD import.
