The DNP3 specification allows for different RTU status conditions to be reported with point s. These status parameters are reported as a 7, 6, or 5 bit integers with each bit representing a different state. Instead of having a PI point for each status bit, the PI DNP3 interface has just one point to keep track of the status. This status point can be an integer or even a float point , but a status of "36" does not tell the user as much about the state of the point , but "36" translated to OffLine_CommLost_OverRange is more meaningful. For this reason, five .csv files are included with the PI DNP3 interface.
-
DigitalSet_DNP_BinaryStatus.csv
-
DigitalSet_DNP_CounterStatus.csv
-
DigitalSet_DNP_DoubleBit.csv
-
DigitalSet_DNP_FreezeCodes.csv
-
DigitalSet_DNP_AnalogStatus.csv
To create the digital sets, import the .csv files using the PI SMT. After the sets are created, create or edit the digital status points and set their digitalset attribute to the name of the correct digital state set.
