Counter freeze request point

The Userint2 attribute is also necessary when using input defined PI points to request freezing of 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) 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. The following table lists the value that the Userint2 attribute must be set to when using an input point to freeze binary counters.
