5.3.4 Counters
The following table 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. The
default Binary Counter and Frozen Counter event buffer sizes are set to 30.
The “Default Deadband,” and the “Default Change Event Assigned Class” columns are used to represent the absolute
amount by which the point must change before a Counter change event will be generated, and once generated in
which class poll (1, 2, 3, or none) will the change event be reported.
