1 These types are considered to be equal. For example, a counter event (object 22) for point number 3 will be saved to a Counter ( Location5 = 20 ) PI point with point number 3 ( Location2 = 3 ).
2 This generic type is associated with DNP output objects. This type also needs specific InstrumentTag and Userint2 values.
3 This generic type is associated with DNP object 20 when requesting to freeze counter values. This type also needs specific Location2 and Userint1 values. If the point is used as an input point, then Userint2 will also be needed.
4 This type is associated with DNP Octet String and requires the use of the InstrumentTag attribute.
5 Object 40 can acquire the value (40) or status (-40) from the Remote Terminal Unit (RTU).
