Address |
Plant SCADA Type |
DNP3 Type |
Description |
|---|---|---|---|
|
BI<n>.Val |
DIGITAL |
Binary Input Value Object 01 Variations 1,2 Object 02 Variations 1,2,3 |
R/O. Current state of Binary Input (This is Bit 7 of Status byte) |
|
BI<n>.Val.TS |
LONG |
Binary Input Time Stamp (seconds since 1970) |
UTC time when value last changed or when the value was acquired from the initial integrity poll |
|

Binary Input Quality |
OPC quality of point converted from value of flags. |
where:
-
n = Point index number (range from 0 to 2048)
-
R/O = read only
-
W/O = write only
-
R/W = read or write
