DNP3 Data Files
Basically, the index number of DNP objects of each type is evaluated by the
firmware automatically per the number of elements. For example, if a Binary
Input object file was configured as an element, the highest index number of the
Binary Input object is 15. The index number can only be increased by 16. If a
Double-Bit Binary Input object file was configured as an element, the highest
index number of the Double-Bit Binary Input object is 7. The index number can
only be increased by 8.
As another example, if a 16-bit Analog Input object file was configured as an
element, the highest index number is 1. Except for Binary and Double-Bit Binary
type objects, the index number can be increased by 1.
