POINT NAME/DESCRIPTION COUNTERS
The following details lists both Binary Counters (Object 20) and Frozen Counters (Object 21).
When a freeze function is performed on a Binary Counter point, the frozen value is
available in the corresponding Frozen Counter point. 869 Digital Counter values are
represented as 16 or 32-bit integers. The DNP 3.0 protocol defines counters to be unsigned
integers. Care should be taken when interpreting negative counter values.
