Appendix
The structure instance x corresponds to the DDL participant
address (1-14). Input and output process data (PDIN and
PDOUT), as well as diagnostic data (DIAGIN), are defined as
needed.
You can find the structure and diagnostic length in the DDL
participant description.
Combination modules and the EP pressure regulator consist of
two function groups with the same structure instance for the
input and output sides, respectively. The parameters are always
assigned to the output side and the diagnostic data to the input
side.
The following table provides an example configuration with the
respective IDNs for the process data:

13.4 DDL participant parameters
The parameter descriptions of the individual DDL participants
can be found in the respective operating instructions.
The parameters of the individual DDL participants can be
transferred in the CP2 with the corresponding structure
elements.
In this way, for example, the parameters of a valve unit are
written to the IDN/S-0-1502.x.20, where the structure instance
x stands for the corresponding DDL address.
