2.2 Functions
Media redundancy with planned duplication (MRPD)
If media redundancy is to be achieved in the case of short update times (together with IRT),
you must use the MRP extension "Media redundancy with planned duplication (MRPD)".

Shared Device
IO device that makes its data available to up to four IO controllers.
The interface module supports Shared Device operation at the submodule level. A
prerequisite for using this function is that the I/O modules also support this.
Please note the following if the Engineering System does not perform a validity check of the
Shared Device projects:
● Make sure that the configurations are consistent. In particular, the modules or
submodules may only be assigned to one controller. Multiple assignment will result in an
error; the module will only be available in the first controller.
● If you reconfigure Shared Device configurations without the validity check mentioned
above, you have to commission the ET 200MP 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.

Module-internal Shared Input/Shared Output (MSI/MSO)
The module-internal Shared Input function allows an input module to make its input data
available to up to four IO controllers. Each controller has read access to the same channels.
The module-internal Shared Output function allows an output module to make its output data
available to up to four IO controllers. One IO controller has write access. Up to three
additional IO controllers can have read access to the same channels.
The combination of isochronous mode and Shared Device is not supported.
