670 series 2.2 ANSI
Communication protocol manual
IINx.b - where x is a 1 for the first octet and x is a 2 for the second. b identifies the bit
number.
Thus, IIN2.0 refers to the first bit in the second octet.
See the DNP3 Specification Volume 3 Application Layer (Section 5 Detailed IIN Bit
Descriptions) for more detailed descriptions of IIN bits.

Bit index
Descriptions and conditions
IIN1.0
All stations – set after a broadcast message (any message using a
destination address of 0xfff0 or above) has been received. Does not
indicate an error condition
IIN1.1
Class 1 event data available. Can be set at any time and does not
indicate an error condition.
IIN1.2
Class 2 event data available. Can be set at any time and does not
indicate an error condition
IIN1.3
Class 3 event data available. Can be set at any time and does not
indicate an error condition
IIN1.4
Time synchronization required from master. Can be set at any time and
does not indicate an error condition. This bit is set according to the PST
setting "tSyncTimeout" when time synchronization is via DNP3.
IIN1.5
Local mode. Set if some points are uncontrollable via DNP3.
IIN1.6
Device trouble. Set if the IED has detected device problems. This bit is
set when the IED's "Internal Fail" flag is set.
IIN1.7
Device restart. Set only under specific conditions. Does not indicate an
error condition
IIN2.0
Function unknown. Generally means that the function code (octet 2 of the
request header) cannot be processed.
IIN2.1
Object unknown. Generally means that the function code could be
processed but the object group / variation could not be processed
IIN2.2
Parameter error. Generally indicates that both function code and object
group / variation could be processed but that the qualifier / range field is
in error.
IIN2.3
Buffer overflow. Indicates that an event buffer has overflowed, and that
change events, of at least one type, have been lost. Binary event buffer
size is 1000. Counter event buffer size is 1000. Frozen event counter
event are not supported. Analog event buffer size is 1000.
IIN2.4
Requested operation is already executing.
IIN2.5
Configuration corrupted.
IIN2.6
Reserved. Always 0.
IIN2.7
Reserved. Always 0.
