Shared device
IO device which makes its data available to multiple IO controllers.
The interface module supports shared device at submodule level.
If there is no validity check of the shared device projects by the Engineering System, note
the following:
●
Make sure the configurations are consistent. In particular, modules or submodules may
only be assigned to one controller. Multiple assignment will result in an error; the module
or submodule will only be available in the first controller.
●
If you reconfigure the shared device configurations without the validity check mentioned
above, you must commission the ET 200SP once again. This means that you have to
reload the projects of all involved IO controllers to the specific CPU after reconfiguration
and, if necessary, switch the interface module POWER OFF/POWER ON.
You can find more information on this topic in the STEP 7 online help and:

Note
In the case of a shared device application, make sure that all controllers work with the same
send clock. If controllers do not have the same send clock, the differing send clock can result
in communication relationships that are not set up.
If you set up all controllers in one project, the same send clock is ensured. Set the same
send clock for engineering in separate projects.
Submodules
The IM 155-6 PN ST interface module supports the division of I/O modules into up to 4
submodules. This allows parts of an I/O module to be separately configured and
parameterized.
It is possible to assign each of these submodules to different IO controllers.
The functions:
●
Firmware update
●
Write I&M data
●
Calibration
●
PROFIenergy
can only be executed if you have configured submodule 1 during configuration.
