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) and type 30 (Analog Input).
3. The point tables for Binary Input and Analog Input objects contain a field which
defines which event class the corresponding static data has been assigned to.
4. For this object, the qualifier code must specify an index of 7 only.
5. Warm Restart (function code 14) is supported although it is not required by the DNP
level 2 specification.
6. Object 1 Variation 1 always indicates ON LINE for all points.
