As an example, a Binary Input Config File shown below has 10 elements. B30:0/
0 and B30:0/1 can be configured for Class Level 0, 1, 2, or 3 for DNP3 Index 0…15
of the Binary Input Object File. B30:1/0 and B30:1/1 can be configured for Class
Level for DNP3 Index 16…31 of the Binary Input Object File. Default Class Level
is 0. Any other bits are reserved.
Class Level of Index 0…15 is 1(B30:0/0 and B30:0/1), Class Level of Index 16…31
is 2(B30:1/0 and B30:1/1), Class Level of Index 32…47 is 3(B30:2/0 and B30:2/1),
and Class Level of other Indexes are 0.
DNP3 Binary Output Object
The supported object group and variations are listed in this section. The
controller responds with the default group and variation when the DNP3
Master requests to read the object with Any Variation.
Binary Output Static Objects:
• g10v0 – Binary Output – All Variations
• g10v2 – Binary Output – Output status with flags (default)
Binary Output Command Objects:
• g12v1 – Binary Command – Control relay output block (CROB)
Related Object File Number:
• Binary Output Object File Number
Related Configuration File Number:
• Binary Output Config File Number
To generate a Binary Output Object from the DNP3 Subsystem in the
controller, you should configure Binary Output Object File Number in the
DNP3 Slave Application Layer Configuration file.
When the Binary Output Object File is configured, Index number starts from
0. 1 bit is used for 1 Index.
