Default Variations; Internal Indication Bits - GE Power Quality Meter Series Instruction Manual

8.1 DNP 3.0 PROTOCOL
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.
The following table specifies the default variation for all objects returned by the relay. These are the variations
that will be returned for the object in a response when no specific variation is specified in a request.

BIT DESCRIPTION
POSITION
7 Device Restart -- set when PQM powers up, cleared by writing zero to object 80
4 Need Time -- set whenever the PQM has a "CLOCK NOT SET" alarm, cleared by
setting the clock
1 Class 1 -- indicates that class 1 events are available
2 Class 2 -- indicates that class 2 events are available
3 Class 3 -- indicates that class 2 events are available
3 Buffer Overflow -- generally indicates that the host has not picked up the event
data often enough
