The Userint1 attribute is used in requests to freeze or freeze/clear Binary Counters (Object 20). The freezing of this object is specified by setting the Location5 attribute to a value 20. The value of the Location2 attribute must be set to the starting index of the Counter(s) that is to be frozen. The value of the Userint1 attribute is used to set the stopping index of the Counter(s) that are to be frozen. If all Counters are to be frozen, then the Userint1 value must be set to a value of -1. If the point is being used as an input point, then Userint2 must also be defined. If the freeze request comes from an output PI Point, refer to the Counters.
Freezing/Clearing Counters section for the DNP3 function code associated with the output value of this PI Point. The following table demonstrates how the value of Userint1 is interpreted.
