F.2.3 COUNTERS
The following table lists both Binary Counters (Object 20) and Frozen Counters (Object 21). When a freeze function is per-
formed on a Binary Counter point, the frozen value is available in the corresponding Frozen Counter point.
A counter freeze command has no meaning for counters 8 and 9. T60 Digital Counter values are represented as 32-bit inte-
gers. The DNP 3.0 protocol defines counters to be unsigned integers. Care should be taken when interpreting negative
counter values.
