Allocation of the Input and Output Data
The process data is exchanged via the PROFINET IO using the higher-level
controller (IO controller).
The output data including all process data qualifiers (IOPS and IOCS) is
transferred cyclically from the IO controller to the fieldbus coupler. The fieldbus
coupler sends the input data including all process data qualifiers (IOPS and IOCS)
cyclically to the IO controller.
When configuring the fieldbus node, the individual I/O modules are configured in
accordance with their physical arrangement (slot-oriented).
These can be found as part of the configuration based on individual requirements
in the hardware catalog of the configuration software. All specific information on
the relevant I/O modules is contained in the associated GSD file.
Information
More Information on module-type allocation of the I/O modules!
Allocation of the I/O modules for the different module types and selectable
submodule types is listed in the appendix. A tabular listing contains the
chapter "Module and submodule Types of the I/O Modules".
Figure 39: Allocation of the Input and Output Data
In productive data exchange, one or two byte IOXS process data qualifiers are
available for each configured module providing information on the validity of the
submodule data. The process data qualifiers are an integral part of the maximum
length of the telegram with the provider and consumer data and must therefore be
considered when installing the modules.
