• No class can be assigned to this Object.
Indication
Bit Location
Description
All Stations
1
Occurs when previous message was a broadcast message.
Class 1 data
2
Occurs when data configured as Class 1 is available (ready to be
sent). Master station should request this class data from the meter
when this bit is set in a response. Additionally, the data can be set
by an unsolicited message when configured for that.
Class 2 data
3
Same as above, but for Class 2.
Class 3 data
4
Same as above, but for Class 3.
Need Time
5
Occurs when the "Time Sync Renewal Interval" has elapsed or at
power up, informing the user that the meter needs time synchroni-
zation. The Master of the DNP network should synchronize the time
by writing Object 50 into the meter. When time is written, the indi-
cation is cleared.
This indication is also cleared when the Master explicitly writes a 0
into this bit of Object 80.
Local
6
Set when some, or all, of the digital output points in the meter are
in the Local state, meaning the Master cannot control the outputs
because the meter is already using them for limits, alarms, or Elec-
troLogic.
Device Trouble
7
Set when an abnormal condition exists in the Meter (configuration is
bad or another error prevents proper functioning).
Device Restart
8
Set when the device starts up - is an indication that the device has
restarted. Master station should send a clear to this Indication, so if
in the future it appears again, it will be known that the meter
restarted, again. It is also set after a Cold-Restart command.
Bad Function
9
Occurs if the function code in a User Data request is not supported.
Object Unknown2
10
Occurs if an unsupported object is specified for accessing.
Out of Range
11
Occurs for most other errors in a request, such as requesting points
that don't exist or direct operate requests in unsupported formats.
Buffer Overflow
12
Occurs if any buffer of the DNP3 meter application has overflowed.
For example, the event buffer (for classes), or the transmission buf-
fer due to a lengthy reply.
Already Executing
13
Request understood and already in operation.
