88 Function Description
7.7.2.2

Process Data Handling

The handling concerning the PROFINET IO process data is the same for physical
and virtual option modules:
•
The input data of the represented I/O module provided to the IO controller is
set to zero.
•
The output data provided to the represented I/O module by the IO controller
is filtered by the fieldbus coupler.
The PROFINET IO provider or consumer states (IOXS) are controlled depended
to the K-Bus state and the access right of the AR to the particular I/O module.
This corresponds to the behavior of non-option modules.
7.7.2.3

Identification

PROFINET IO offers the opportunity to request the real configuration of an
IO device independent to an established IOxAR.
In general, option modules are represented by the ModuleIdentNumber
0x00008404. The distinction between physical and virtual option modules is done
by the SubmoduleIdentNumber
If there is no IOxAR established after restart of the station, the data set
„RealIdentificationData" delivers the ModuleIdentNumber 0x00008404 and the
SubmoduleIdentNumber 0x01000000 for slots mounted with physical option
modules. There are no virtual option modules available in this operating state.
Is an IOxAR already established to the station the data set
„RealIdentificationData" delivers the ModuleIdentNumber and the
SubmoduleIdentNumber of the represented I/O module for an option module slot.
For option modules which are not owned by the established IOxAR, the
ModuleIdentNumber 0x00008404 and the appropriate SubmoduleIdentNumber is
registered within data set.
The table below shows the delivered ModuleIdentNumber or
SubmoduleIdentNumber for option modules in dependence to the current
operating state of the station.
