CHAPTER 5: DNP COMMUNICATIONS DNP IMPLEMENTATION
750/760 FEEDER MANAGEMENT RELAY – COMMUNICATIONS GUIDE 5 - 3
Note 1: The data link layer confirmation mode, confirmation time-out, and number of
retries are all configurable. Refer to the DNP Configuration section in Chapter 5 of
the instruction manual for more details.
DNP Implementation
The table below gives a list of all objects recognized and returned by the relay. Additional
information is provided on the following pages including a list of the default variations
returned for each object and lists of defined point numbers for each object.
Implementation Table Notes:
1. For this object, the quantity specified in the request must be exactly 1 as there is only
one instance of this object defined in the relay.
2. All static input data known to the relay is returned in response to a request for Class 0.
This includes all objects of type 1 (Binary Input), type 10 (Binary Output) and type 30
(Analog Input).
3. The point tables for Binary Input and Analog Input objects contain a field which
defines to which event class the corresponding static data has been assigned.
4. For this object, the qualifier code must specify an index of 7 only.
