As an example, an Analog Input Config File is shown below. These files have 10
elements each.
B36:0/0 and B36:0/1 can be configured for Class Level 0, 1, 2 or 3 for DNP3
Index 0 of the 16 bits Analog Input Object File.
B36:1/0 and B36:1/1 can be configured for Class Level for DNP3 Index 1 of the
Analog Input Object File. Default Class Level is 0. Any other bits are reserved.
In the example below, for 16-bit Analog Input Config File, Class Level of Index
0 is 1(B36:0/0 and B36:0/1), Class Level of Index 1 is 2(B36:1/0 and B36:1/1), Class
Level of Index 2 is 3(B36:2/0 and B36:2/1), and Class Level of other Indexes
are 0.
For a 32-bit Analog Input Config File, Class Level of Index 10 is 1(B37:0/0 and
B37:0/1), Class Level of Index 11 is 2(B37:1/0 and B37:1/1), Class Level of Index 12
is 3(B37:2/0 and B37:2/1), and Class Level of other Indexes are 0.
For Short Floating Point Analog Input Config File, Class Level of Index 20 is
1(B38:0/0 and B38:0/1), Class Level of Index 21 is 2(B38:1/0 and B38:1/1), Class
Level of Index 22 is 3(B38:2/0 and B38:2/1), and Class Level of other Indexes
are 0.
