7-22
The meter has an 8-byte Binary Counter Value while DNPcan only give a 4-byte value. By
using this scaling, the user can get the proper range of data. The scaling value represents the
power of 10.
•Delta Values: 4-byte unsigned integer
If the Current Binary Counter value is different from the Previous value more than Delta values,
the Counter Change Event value will be generated if it is assigned to a Class.
•Class assignments (Currently bits 5,4,3,2,1 and 0 are used): 8-bit bitmap
When bit 5 is set, the Counter Change Event value will not be generated.
When bit 5 is clear, bit 4 and bit 3 will assign the Counter Change Event value to a Class.
When bit 2 is set, the Frozen Counter Event value will not be generated.
When bit 2 is clear, bit 1 and bit 0 will assign the Frozen Counter Event value to a Class.
•Reserved: 7 bytes. Reserved for future use.
