Related Object/Configuration File Number:
• Data-Set Prototypes Object File Number
• Data-Set Descriptors Object File Number
To generate a Data-Set Object from the DNP3 Subsystem in the controller,
configure Data-Set Prototypes/Descriptors Object File Number in the DNP3
Slave Application Layer Configuration file and also the Maximum Number of
Data-Set Prototypes/Descriptors Files.
Each Data-Set Prototypes Object file (N data file) can have up to 10 elements of
Data-Set Prototypes, and each Data-Set Descriptors Object file (N data file) can
have up to 10 elements of Data-Set Descriptors.
As an example, with Data-Set Prototypes files, if you configure Data-Set
Prototypes Object File Numbers to 50 and Maximum Number of Data-Set
Prototypes Files to 9, N Data files 50…58 are reserved to store the structure of
the Data-Set Prototypes configuration.
As an example, with Data-Set Descriptors files, if you configure Data-Set
Descriptors Object File Number to 60 and Maximum Number of Data-Set
Descriptors File to 9, N Data files 60…68 are reserved to store the structure of
the Data-Set Descriptors configuration.
